Updated July 29, 2026: Electrical code, utility, permit and rebate requirements can change. The electrical requirements for a heat pump also depend on the exact equipment, existing electrical service, backup-heating design and other household loads. Have the proposed installation evaluated by appropriately qualified professionals before equipment is ordered.
Heat pump electrical requirements in BC are project-specific. Installing a heat pump does not automatically mean a home needs a 200-amp service or a complete electrical-panel replacement. Some homes need only new branch circuits and disconnecting equipment. Others need panel modifications, load management or a full utility service upgrade.
The correct answer comes from the electrical requirements of the selected heat pump and indoor equipment, the home’s existing electrical capacity and other loads such as electric water heating, cooking, EV charging, hot tubs and electric backup heat.
A 100-amp home can sometimes support a heat pump. A 200-amp home can still have capacity or panel-space problems. Panel size alone therefore does not determine whether a project is ready for electrification.
This guide explains panel capacity, service capacity, breakers, dedicated circuits, electric auxiliary heat, load calculations, smart load management, permits and current BC rebate considerations for homeowners planning a heat pump installation.
Does a Heat Pump Require a 200-Amp Electrical Service?
No.
There is no universal rule that every residential heat pump requires a 200-amp service.
A 100-Amp Home May Be Able to Support a Heat Pump When:
- The existing electrical demand leaves enough capacity.
- The selected heat pump has appropriate electrical requirements.
- Large electric resistance backup is not required.
- Other major electric loads are limited or managed.
- The electrical equipment is otherwise suitable.
A 200-Amp Home May Still Need Electrical Work When:
- The panel is already heavily loaded.
- There are no suitable breaker spaces.
- Large electric backup heat is being added.
- An EV charger, electric water heater or other major load is also being installed.
- The panel or service equipment requires replacement for another reason.
Do Not Size the Electrical Service From the Heat Pump Tonnage Alone
A three-ton heat pump does not translate into one universal electrical load.
Electrical requirements vary by:
- Manufacturer
- Model
- Compressor technology
- Indoor equipment
- Electric backup heat
Have the Actual Proposed Equipment Evaluated
The electrician should work from the equipment specifications and applicable electrical rules rather than from generic assumptions such as:
“Heat pump equals 200 amps.”
What Should Be Checked Before Heat Pump Equipment Is Ordered?
Electrical planning should happen during system design, not after the outdoor unit arrives.
Review the Existing Electrical Service
Important information includes:
- Service rating
- Main breaker or switch
- Panel condition
- Available breaker spaces
- Existing large loads
- Previous electrical modifications
Review the Proposed HVAC Equipment
Obtain electrical information for:
- Outdoor heat pump
- Air handler
- Ductless indoor equipment where applicable
- Electric backup heater
- Hydronic module
- Circulation pumps
Review Other Planned Electrification
Tell the electrician if you are also planning:
- EV charger
- Heat pump water heater
- Electric range
- Induction cooking
- Hot tub
- Suite
- Home addition
Plan the Whole Home Once
Designing today’s heat pump without mentioning next month’s EV charger is an efficient way to pay for electrical planning twice.
1. Electrical Panel Size and Service Capacity Are Not the Same Thing
Homeowners often use the words panel and service interchangeably.
They describe related but different parts of the electrical system.
Electrical Service
The service is the electrical supply available to the property from the utility and the associated service equipment.
Electrical Panel
The panel distributes electricity to individual branch circuits through breakers.
Why the Difference Matters
A panel replacement does not automatically increase the amount of electrical capacity available from the utility.
Similarly, adding a sub-panel may provide more physical circuit spaces without increasing total service capacity.
Three Separate Questions
Before heat pump installation, ask:
- Is there enough electrical service capacity?
- Is the existing panel suitable?
- Is there enough physical and electrical capacity for the required circuits?
Those questions can have different answers.
2. A 100-Amp Service May Be Enough for a Heat Pump
A 100-amp service should not be rejected automatically.
BC Hydro Recommends a Load Assessment
BC Hydro advises homeowners considering new electric loads such as heat pumps or EV chargers to have electrical capacity professionally evaluated before unnecessarily increasing the service size.
Review the official BC Hydro home electrical capacity guidance.
Why Some 100-Amp Homes Can Work
The home may already have:
- Gas water heating
- Gas cooking
- No EV charger
- Limited electric resistance heating
and therefore have enough available electrical capacity for the proposed heat pump.
Existing Electric Homes Can Also Be Interesting
A home with electric resistance heating may already have electrical capacity dedicated to space heating.
Replacing much of that resistance heating with a heat pump can change the overall demand calculation significantly.
Do Not Assume 100 Amps Is Always Enough Either
Every home has a different combination of loads.
3. A 200-Amp Panel Does Not Guarantee Spare Capacity
Seeing “200A” on the main breaker does not end the analysis.
A 200-Amp Home May Already Have:
- EV charger
- Electric water heater
- Electric range
- Electric dryer
- Hot tub
- Electric baseboards
- Secondary suite
- Workshop loads
Service Capacity and Physical Panel Space Are Both Relevant
There may be:
- Enough total capacity but no appropriate breaker spaces
- Plenty of breaker spaces but insufficient service capacity
- Both problems
- Neither problem
Measure and Calculate
BC Hydro specifically recommends professional load calculations and cautions against unnecessarily oversizing service upgrades.
4. Heat Pump Circuits Must Match the Actual Equipment
Do not choose the breaker first and the heat pump later.
The Equipment Nameplate and Installation Instructions Matter
Relevant electrical information can include:
- Supply voltage
- Phase
- Minimum circuit ampacity
- Maximum overcurrent protection
- Manufacturer wiring requirements
Equipment of Similar Heating Capacity Can Have Different Electrical Requirements
Differences can result from:
- Compressor design
- Inverter electronics
- Outdoor fan motor
- Indoor equipment
- Approved matched-system configuration
Do Not Copy the Breaker From the Old Air Conditioner
The old AC circuit may or may not meet the requirements of the new heat pump.
The proposed circuit should be evaluated for:
- Conductor size
- Breaker or fuse
- Disconnect
- Existing wiring condition
- New equipment requirements
5. Outdoor and Indoor Equipment May Need Different Electrical Circuits
A central heat pump installation can involve more than the outdoor compressor circuit.
Outdoor Unit
Requires the electrical supply specified for the selected equipment.
Indoor Air Handler
A full-electric air handler may require its own electrical supply.
Gas Furnace
A dual-fuel system retains the furnace’s electrical requirements for:
- Controls
- Ignition
- Inducer
- Blower
Ductless Systems
Depending on manufacturer design, power may be supplied:
- To the outdoor unit with interconnection to indoor units
- Through another approved electrical arrangement
Follow the selected equipment instructions rather than assuming every mini-split is wired identically.
Air-to-Water Systems
Additional electrical loads can include:
- Hydronic module
- Circulation pumps
- Backup heater
- Fan coils
- Domestic hot-water components
6. Electric Backup Heat Can Create a Large Additional Electrical Load
The compressor is not always the largest electrical planning issue.
Electric resistance backup can be much more demanding.
Central Full-Electric Systems May Include:
- Electric auxiliary heat
- Emergency heat
- Electric resistance stages
Why Backup Heat Matters
Resistance heating needs approximately one unit of electrical input for each equivalent unit of direct resistance heat delivered.
A heat pump operating at a COP well above 1 requires much less electrical input for the same useful heat output.
Backup Size Should Be Designed
It should not automatically equal the entire peak heating load when the project does not require that strategy.
Consider:
- Heat pump low-temperature capacity
- Home heating load
- Other backup heat
- Local climate
- Homeowner redundancy requirements
Oversized Electric Backup Can Trigger Electrical Upgrades
BC Hydro’s current contractor guidance warns that large resistance-heater packages can add substantial panel load and may contribute to the need for electrical upgrades.
HVAC and Electrical Design Need to Talk to Each Other
Choosing auxiliary heat without considering electrical capacity is a surprisingly efficient method for expanding the project scope after the quote is signed.
7. Dual-Fuel Heat Pumps Have a Different Electrical Profile
A dual-fuel system normally uses a heat pump with a gas furnace.
The Heat Pump Still Needs Electrical Power
This includes:
- Outdoor compressor
- Outdoor fan
- Controls
The Gas Furnace Also Needs Electricity
Modern furnaces typically use electrical power for:
- Control board
- Ignition
- Inducer
- Blower
But Large Electric Resistance Backup May Not Be Required
The gas furnace can provide the alternate heating source according to the hybrid control strategy.
This can produce a different electrical-load profile from an all-electric central system with large resistance heat strips.
Dual Fuel Does Not Mean No Electrical Planning
The heat pump circuit, furnace power and controls still need to be evaluated and permitted as applicable.
8. Existing Electric Heating Changes the Electrical Calculation
Heat pump installation does not always represent a completely new electrical heating load.
Electric-Baseboard Home
The property may already have substantial electric resistance heating circuits.
Electric-Furnace Home
The existing furnace may already have significant electrical capacity dedicated to heating.
Replacing Resistance Heating With a Heat Pump Can Reduce Heating Demand
The heat pump can deliver the required space heat using considerably less electricity than pure resistance heating under normal compressor operation.
But Do Not Disconnect Existing Heat Before the Design Is Complete
Determine:
- Which electric heaters remain
- Which are decommissioned
- Which provide backup
- How current rebate requirements treat the existing equipment
Existing Circuits Are Not Automatically Reusable
A baseboard circuit does not automatically become a compliant heat pump circuit simply because both use electricity.
9. Panel Space and Electrical Capacity Are Separate Problems
A common site visit reveals a panel with sufficient overall service capacity but no convenient space for the required new breakers.
Possible Solutions May Include:
- Approved panel reconfiguration
- Sub-panel
- Panel replacement
- Other compliant electrical work
A Sub-Panel Does Not Create More Utility Capacity
It expands circuit distribution.
The total electrical load still needs to fit within the available service and applicable calculation.
Do Not Use Unapproved Breaker Arrangements
Breaker type, tandem use and panel configuration must be compatible with the listed electrical equipment and applicable requirements.
The Electrical Contractor Should Determine the Solution
This is not a homeowner puzzle involving whichever breaker physically fits into the remaining hole.
10. Load Management May Avoid Some Electrical Service Upgrades
Sometimes the problem is not total daily electricity use.
It is the possibility that several large loads operate at the same time.
Load Management Can Coordinate Loads Such As:
- EV charging
- Water heating
- Heat pump backup heat
- Other controllable electrical loads
Example Concept
A control system may prevent or reduce one flexible load while another high-priority load is operating.
BC Hydro Guidance
BC Hydro recommends exploring home energy management and other load-management options before unnecessarily oversizing electrical service.
Current BC Hydro heat pump contractor guidance also identifies load-share devices and smart electrical panels as possible tools in projects where calculated loads would otherwise exceed available panel capacity.
Load Management Is Not a Universal Substitute for a Service Upgrade
It needs to be:
- Suitable for the loads
- Approved for the application
- Designed by qualified professionals
- Installed in compliance with applicable electrical requirements
11. Future EV and Water-Heating Loads Should Be Considered
A heat pump may be only the first major electrification project.
Future Loads Can Include:
- EV charger
- Heat pump water heater
- Electric range
- Induction cooktop
- Electric dryer
- Hot tub
- Secondary suite
Tell the Electrician About Planned Projects
The load calculation can then consider near-term changes rather than optimizing the service for one piece of equipment today.
Do Not Automatically Oversize for Every Imaginary Future Appliance
BC Hydro advises avoiding unnecessarily oversized service upgrades because they can increase installation and equipment costs.
Good Planning Finds the Middle Ground
Provide enough flexibility for realistic plans while using accurate load information and management strategies where appropriate.
12. Old or Unsuitable Electrical Equipment May Still Need Work
Available amperage is not the only concern.
The Electrical Inspection May Identify:
- Damaged equipment
- Improper previous modifications
- Unsuitable panel configuration
- Corrosion or moisture damage
- Insufficient circuit capacity
- Service equipment needing modification
A Heat Pump Does Not Cause Pre-Existing Electrical Problems
Installation can simply be the project that finally requires them to be addressed.
Do Not Ignore Heat Damage or Repeated Breaker Trips
Signs such as:
- Burning smell
- Melted insulation
- Hot electrical equipment
- Arcing
- Repeated breaker trips
require professional electrical attention.
Never Install a Larger Breaker to Stop Nuisance Trips
Overcurrent protection must match the circuit and equipment requirements.
13. Heat Pump Electrical Work Is Regulated in British Columbia
Technical Safety BC identifies residential heat pumps as regulated equipment under BC electrical safety requirements.
Electrical Permit
Technical Safety BC states that, in most cases, installing or upgrading a residential heat pump requires an electrical permit.
Who Can Perform the Electrical Work?
Technical Safety BC states that the person performing regulated heat pump electrical work must hold the required electrical qualification, or be a refrigeration mechanic with the applicable Electrical Refrigeration FSR qualification, and work under the required licensed contractor or permit-holder structure.
Licensed Contractor
When a licensed contractor performs the installation, the contractor normally obtains the permit for its regulated work.
Natural Gas Equipment
If the project modifies or removes a natural gas furnace or boiler, gas permitting and qualified gas work must also be addressed.
Review the current Technical Safety BC heat pump permit guidance.
Municipal Jurisdiction
Depending on location, the Authority Having Jurisdiction may be Technical Safety BC or a municipality.
Confirm the applicable permit process for the specific property.
14. Current BC Electrical Service Upgrade Rebates Have Specific Rules
Do not assume that every panel upgrade performed during heat pump installation qualifies for a rebate.
Current Energy Savings Program
For invoices dated on or after July 6, 2026, the CleanBC Better Homes Energy Savings Program currently includes an electrical service upgrade rebate for eligible households converting from fossil-fuel primary space and/or water heating to a heat pump through the program.
The Utility Service Must Actually Be Upgraded
Current requirements state that the electrical utility must upgrade the service connection to:
- 100 amps
- 200 amps
- 400 amps
as applicable to the approved project.
Panel-Only Work Is Not Enough for This Specific Rebate
Under current program rules, a panel or sub-panel upgrade without a utility electrical service upgrade does not qualify for the electrical service upgrade rebate.
Current Maximum Rebate Levels
| Energy Savings Program Income Level | Maximum Electrical Service Upgrade Rebate |
|---|---|
| Income Level 1 | Up to $5,000 |
| Income Level 2 | Up to $3,500 |
| Income Level 3 | Up to $1,500 |
The rebate is subject to eligible costs, income qualification, contractor requirements, deadlines and all other current program conditions.
Timing Matters
Current program rules require the qualifying electrical service upgrade to be installed within six months of the heat pump installation.
Check Before Starting Electrical Work
Review the current Better Homes BC Energy Savings Program requirements rather than assuming ordinary panel work will qualify.
Panel Upgrade vs Electrical Service Upgrade
These phrases describe different scopes of work.
| Term | What It Usually Means |
|---|---|
| New heat pump circuit | A new branch circuit is added for specific equipment without necessarily replacing the panel or utility service. |
| Sub-panel | Additional circuit-distribution space is added, but total service capacity does not automatically increase. |
| Panel replacement | The electrical distribution panel is replaced, possibly while retaining the same overall service rating. |
| Service upgrade | The property’s electrical service capacity and associated utility/service equipment are increased as required. |
Why Homeowners Should Ask for Specific Language
“Electrical upgrade included” is too vague.
The quote should state whether it includes:
- Branch circuit
- Breaker
- Disconnect
- Sub-panel
- Panel replacement
- Utility service upgrade
- Permit
These Costs Can Be Very Different
The electrical scope should therefore be resolved before comparing heat pump proposals.
What Do MCA and MOCP Mean on a Heat Pump?
Heat pump documentation commonly includes electrical values such as minimum circuit ampacity and maximum overcurrent protection.
MCA
Minimum Circuit Ampacity is used in determining the minimum ampacity required for the circuit conductors supplying the equipment.
MOCP
Maximum Overcurrent Protection identifies the maximum permitted overcurrent protective device rating specified for the equipment under its listing and design.
Why Homeowners Should Care
These numbers demonstrate why:
- Compressor running amperage alone does not determine wire size.
- The old AC breaker should not automatically be reused.
- A breaker should not be enlarged casually.
Leave Circuit Design to the Electrician
The installer or electrician must apply the equipment information together with applicable electrical requirements.
Homeowners do not need to perform conductor and overcurrent calculations themselves.
Does a Heat Pump Need an Outdoor Electrical Disconnect?
Heat pump installations commonly include disconnecting equipment near the outdoor unit as required by the applicable electrical design and equipment installation requirements.
The Disconnect Allows:
- Service personnel to isolate electrical power
- Safe maintenance and repair
- Compliance with applicable electrical requirements
It Is Not the Same as the Breaker
The branch-circuit breaker may be located inside the home’s electrical panel, while the outdoor disconnect provides local isolation near the equipment.
Do Not Operate Damaged Electrical Equipment
If the outdoor disconnect is:
- Broken
- Burned
- Corroded
- Water damaged
have it evaluated by a qualified professional.
What Size Breaker Does a Heat Pump Need?
There is no universal heat pump breaker size.
The Required Circuit Depends on the Exact Model
The equipment information and electrical design determine:
- Conductor requirements
- Overcurrent protection
- Disconnect
Do Not Use Heat Pump Tonnage to Guess Breaker Size
Two systems with similar nominal capacity can have different electrical requirements.
Backup Heat May Have Separate Electrical Requirements
A central system with electric resistance backup can require substantially more electrical capacity than the compressor circuit alone.
Repeated Breaker Trips Are Not a Sizing Tool
If the installed system repeatedly trips its breaker:
- Leave repeated resets alone.
- Do not install a larger breaker yourself.
- Have the equipment and electrical circuit diagnosed.
Ductless Heat Pump Electrical Requirements
A ductless system can have relatively modest electrical requirements compared with some central full-electric systems, but exact requirements vary by equipment.
Single-Zone Mini-Split
A typical installation includes electrical supply for:
- Outdoor unit
- Indoor unit through the manufacturer’s approved arrangement
- Controls and communication
Multi-Zone System
The larger shared outdoor unit may have different electrical requirements from several individual single-zone systems.
Do Not Assume Several Indoor Heads Require Several Utility Services
The electrical architecture depends on the equipment design.
Whole-Home Baseboard Conversion
The electrician should also understand:
- Which existing baseboards remain active
- Which are disconnected
- Whether existing heating demand is being replaced
because those decisions affect the complete electrical picture.
Central Ducted Heat Pump Electrical Requirements
Central systems can range from straightforward heat pump additions to major full-electrification projects.
Heat Pump With Existing Gas Furnace
Electrical work may include:
- Outdoor heat pump circuit
- Disconnect
- Control wiring
- Thermostat upgrades
while the existing gas furnace retains its own electrical supply.
Heat Pump With Electric Air Handler
The project can include:
- Outdoor heat pump circuit
- Air-handler circuit
- Electric backup circuits
- Controls
Large Backup Heaters Can Dominate the Electrical Design
Ask the HVAC contractor:
- How much electric auxiliary capacity is proposed?
- Why is that capacity required?
- At what conditions is it expected to operate?
This discussion should happen before the electrician discovers the answer inside a finalized equipment order.
Full-Electric Heat Pump Electrical Requirements
A full-electric HVAC conversion removes combustion heating from the served space and relies on electric equipment for the heating strategy.
Possible Electrical Loads Include:
- Outdoor heat pump
- Air handler
- Electric auxiliary heat
- Thermostat and controls
Other Electrification May Happen at the Same Time
Removing gas can also lead homeowners to install:
- Heat pump water heater
- Electric or induction cooking
- Electric dryer
Evaluate the Complete Conversion
The HVAC project should not be electrically designed in isolation when several gas appliances are being replaced.
Load Management Can Become More Valuable
Flexible loads such as EV charging or water heating may be managed to reduce simultaneous peak demand where an approved design allows it.
Dual-Fuel Heat Pump Electrical Requirements
Dual fuel combines an electric heat pump with a fuel-fired furnace.
Compared With Some Full-Electric Systems
The installation may avoid the electrical load associated with large resistance backup heating because the furnace supplies alternate heating.
The Project Still Requires:
- Heat pump electrical circuit
- Disconnect
- Furnace electrical supply
- Compatible controls
Do Not Assume the Existing AC Circuit Is Suitable
If a heat pump replaces an old air conditioner, the existing:
- Conductors
- Breaker
- Disconnect
should be checked against the new equipment requirements.
Air-to-Water Heat Pump Electrical Requirements
An air-to-water conversion can shift a large portion of a former boiler heating load onto electricity.
Loads Can Include:
- Outdoor heat pump
- Hydronic module
- Circulation pumps
- Electric backup heat
- Fan coils
- Domestic hot-water equipment
Gas Boiler Conversion
A home previously heated primarily with gas may have relatively little existing electrical capacity dedicated to space heating.
Combi Boiler Conversion
If the old boiler also supplied domestic hot water, the electrical assessment should include the replacement water-heating system.
Do the Load Calculation Early
Electrical constraints can affect:
- Backup-heater selection
- Domestic water-heating design
- Equipment choice
- Project cost
What if the Home Already Has Electric Baseboards?
Existing electric heating can change the retrofit significantly.
The Home May Already Have Substantial Heating Load in the Electrical Calculation
If heat pumps replace much of that resistance heating, the new compressor load is not simply added on top of every existing baseboard forever.
But Some Baseboards May Remain
For example:
- Bathrooms
- Closed bedrooms
- Backup areas
Document the Final Design
The electrical assessment should reflect which heaters:
- Remain connected
- Are decommissioned
- Remain available for backup
Current Rebate Programs Can Have Decommissioning Requirements
Do not disconnect qualifying existing heating before checking the applicable program conditions.
What Changes Electrically When Converting From Gas Heating?
A gas-heated home may have lower existing electrical space-heating demand.
Switching to a Heat Pump Adds Compressor Load
Depending on the design, it may also add:
- Electric air handler
- Resistance backup heat
- Heat pump water heater
Dual Fuel Changes Less
Keeping the furnace as backup can avoid some resistance-heating electrical load.
Full Electrification Changes More
Removing:
- Gas furnace
- Gas boiler
- Gas water heater
can introduce several new electrical loads.
Gas Removal Is a Separate Regulated Scope
Technical Safety BC states that removal or deactivation of regulated gas equipment during a heat pump conversion must be completed safely under applicable gas requirements.
How Is a Home’s Electrical Capacity Evaluated?
This is a job for a qualified professional rather than a homeowner adding breaker labels together.
Information Can Include:
- Electrical service rating
- Existing connected loads
- Applicable demand calculations
- Historical electrical-use data where appropriate
- Proposed new equipment
- Loads being removed
- Future planned loads
BC Hydro Provides Electrical Capacity Data
BC Hydro currently provides homeowners with electrical-capacity information and advises using professional load calculations, including historical meter data where available and appropriate.
See BC Hydro’s home electrical capacity resource.
Do Not Judge Capacity by Monthly kWh Alone
Electrical service planning is concerned with demand and simultaneous loading, not just how many kilowatt-hours a home consumes over an entire month.
Daily Energy and Peak Power Are Different
A home can use relatively little total energy but still have several large appliances capable of operating at the same time.
Can Smart Load Management Avoid a Panel or Service Upgrade?
Sometimes.
Possible Technologies Include:
- Load-share devices
- Energy management systems
- Smart electrical panels
- Managed EV charging
What They Can Do
A suitable system can reduce simultaneous demand by controlling when selected loads operate.
Example
An EV charger is often much more flexible than space heating.
Instead of increasing service capacity solely so the EV charger and every other large load can theoretically operate at full output at the same moment, an approved control strategy may temporarily reduce charging.
Heat Pump Comfort Loads Need Priority
Load management should not casually disable essential heating during winter.
Not Every Project Is Eligible
The electrician should confirm:
- Applicable electrical rules
- Equipment approval
- Utility requirements
- Operating strategy
before relying on load management as the solution.
What Happens During an Electrical Service Upgrade?
A service upgrade can involve considerably more than replacing the breaker panel.
Depending on the Property, Work May Include:
- Utility service connection
- Panel replacement
- Meter base
- Service conductors
- Service mast
- Weather head
- Conduit
- Grounding and bonding work
- Permits and inspections
Utility Coordination May Be Required
Increasing the service can require coordination between:
- Electrical contractor
- Utility
- Authority Having Jurisdiction
- Homeowner
Do Not Assume It Can Be Completed on Heat Pump Installation Day
Scheduling, utility work and inspections can affect the project timeline.
Determine This Before Removing Existing Heating
Particularly during winter, the home should not lose its existing primary heating system while waiting for unresolved electrical service work.
Current BC Rebate for Electrical Service Upgrades
The current CleanBC Better Homes Energy Savings Program has a specific electrical service upgrade rebate.
Who Can Qualify?
Under the current rules, it is for eligible program participants converting from a fossil-fuel primary space and/or water heating system to a heat pump through the Energy Savings Program.
What Upgrade Is Required?
The electrical utility must upgrade the service connection to an eligible:
- 100-amp
- 200-amp
- 400-amp
service as required for the project.
Eligible Costs Can Include:
- Utility connection fees
- Electrical panel or sub-panel upgrade
- Service mast alterations or replacement
- Conduit work
- Meter-base alterations or replacement
- Weather-head work
- Labour
Important Exclusion
A panel or sub-panel upgrade by itself, without an electrical service upgrade by the utility, is not eligible for this specific current rebate.
Current Maximums
- Income Level 1: up to $5,000
- Income Level 2: up to $3,500
- Income Level 3: up to $1,500
Contractor Requirement
Current rules require the upgrade to be purchased, supplied and installed by a Registered Contractor approved for electrical service upgrades under the program.
Six-Month Timing Requirement
The current rules require the utility service upgrade to be installed within six months of the heat pump installation.

Confirm eligibility using the current Energy Savings Program requirements before proceeding.
What Should the Electrical Portion of a Heat Pump Quote Include?
| Item | What Should Be Clear |
|---|---|
| Outdoor heat pump | Exact electrical requirements of the selected model |
| Indoor equipment | Air handler, furnace, hydrobox or other electrical loads |
| Backup heat | Electric heater capacity and circuit requirements where applicable |
| Existing service | Whether available capacity has been evaluated |
| New circuits | Which circuits and breakers are included |
| Disconnect | Outdoor or other required disconnecting equipment |
| Panel work | Reconfiguration, sub-panel or replacement where required |
| Service upgrade | Whether utility service capacity is changing |
| Load management | Any proposed smart panel or load-share equipment |
| Permit | Who obtains the electrical permit and whether the fee is included |
| Utility work | Any utility coordination, connection or service charges |
| Rebate | Which current program is being considered and who handles documentation |
Do Not Accept “Electrical Included” Without Scope
That phrase could mean one new circuit or an entire service upgrade.
Those are not remotely the same project.
Heat Pump Electrical Installation Red Flags
“Every Heat Pump Needs 200 Amps”
Electrical capacity should be evaluated from the actual home and equipment.
“Your 100-Amp Service Can Never Work” Without a Load Calculation
A smaller existing service may be adequate depending on the home’s loads and proposed design.
“You Have 200 Amps, So You’re Fine”
A 200-amp service can still be heavily loaded or have unsuitable panel conditions.
Breaker Size Is Chosen From Tonnage
Use the exact equipment electrical data.
The Old AC Circuit Is Reused Without Evaluation
Existing wiring, overcurrent protection and disconnect equipment should be checked against the new heat pump requirements.
Large Electric Backup Is Added Without Explaining Why
Backup heat can materially affect panel and service requirements.
An EV Charger Is Ignored
Major existing and planned loads belong in the electrical planning discussion.
A Sub-Panel Is Presented as More Electrical Capacity
A sub-panel creates additional distribution space. It does not automatically increase utility service capacity.
Repeated Breaker Trips Are Solved With a Larger Breaker
That is not troubleshooting. It can remove circuit protection without correcting the underlying problem.
No Permit Is Mentioned
Technical Safety BC states that most residential heat pump installations or upgrades require an electrical permit.

Heat Pump Electrical Requirements: Frequently Asked Questions
Does a heat pump require 200-amp service?
No. Some homes can install heat pumps with existing 100-amp service, while other projects require additional electrical capacity. The answer comes from the equipment and home load assessment.
Can I install a heat pump with a 100-amp panel?
Possibly. An electrician should evaluate the existing service, household loads, proposed heat pump and any electric backup heating.
Can a 100-amp house have a ductless heat pump?
Yes in suitable installations. Ductless equipment can have relatively modest electrical requirements, but the whole-home electrical load still needs to be evaluated.
Can a 100-amp house have a central heat pump?
Possibly. Central equipment, indoor air handler and backup heat need to be included in the assessment.
Does a 200-amp service guarantee I can install a heat pump?
No. Existing electrical loads, panel condition, breaker space and the proposed equipment still need to be reviewed.
How do I know whether my electrical service is 100 or 200 amps?
The main service rating may be identified on the main breaker, switch or service equipment. Do not remove panel covers to inspect energized components.
Is my panel rating the same as my available capacity?
No. A panel or service rating describes its rated capacity, while existing electrical demand determines how much additional load can be accommodated.
What is the difference between a panel and electrical service?
The service supplies electrical capacity to the property. The panel distributes that electricity to individual branch circuits.
Does replacing the panel increase electrical service capacity?
Not automatically. A panel can be replaced while retaining the same utility service capacity.
Does adding a sub-panel increase service capacity?
No. It provides additional circuit-distribution space but does not automatically increase the electrical supply available to the home.
Why would a heat pump need a new circuit?
The outdoor and indoor equipment requires an electrical supply designed for the selected equipment and applicable electrical requirements.
Can my heat pump use the old air conditioner circuit?
Possibly, but the existing conductors, breaker, disconnect and circuit condition need to match the new heat pump requirements.
What breaker size does a heat pump need?
There is no universal size. Use the exact equipment electrical specifications and compliant electrical design.
Can I use a larger breaker if the heat pump keeps tripping?
No. Repeated breaker trips require diagnosis. Changing overcurrent protection without confirming conductor and equipment requirements can create a safety hazard.
Why does a compressor not use a breaker matching its normal running amps?
Motor and compressor circuits have specific conductor and overcurrent requirements. Equipment MCA and MOCP values help the electrician design the circuit correctly.
What is MCA?
Minimum Circuit Ampacity is an equipment value used when determining the required ampacity of the electrical supply conductors.
What is MOCP?
Maximum Overcurrent Protection identifies the maximum overcurrent protective-device rating permitted for the equipment under its design and listing.
Is MCA the breaker size?
No. It is one input into circuit design and should not simply be copied as the breaker rating.
Does a heat pump need a disconnect outside?
Heat pump electrical installations commonly require local disconnecting equipment according to the equipment and applicable electrical requirements.
Can I install the disconnect myself?
Electrical work associated with a heat pump is regulated. Use properly qualified electrical professionals and the required permit process.
Does a ductless mini-split need a dedicated circuit?
The required supply arrangement depends on the exact equipment. Follow the manufacturer’s electrical specifications and applicable electrical requirements.
Do all mini-splits run on 240 volts?
No universal voltage applies to all ductless equipment. Verify the selected model.
Does every indoor mini-split head need a breaker?
Not necessarily. Power distribution differs by system and manufacturer.
Does a multi-zone heat pump require more electricity than a single-zone?
It generally serves a larger combined load, but electrical requirements depend on the exact equipment and zones rather than indoor-head count alone.
Does a central heat pump use more electricity than a mini-split?
Not automatically. Capacity, equipment efficiency, building load, airflow and backup heat determine actual use.
What is usually the biggest electrical load in a full-electric central heat pump?
Large electric resistance backup heating can be a major load and sometimes affects panel or service requirements more than the compressor itself.
Does every central heat pump need electric heat strips?
No. Backup strategy depends on heat pump capacity, climate, building load and system design.
Why are heat strips so important to electrical planning?
Resistance heaters can require substantial electrical capacity, particularly when installed in larger stages.
Can smaller backup heat avoid a panel upgrade?
Potentially, when the heating design supports it. Backup capacity should still meet the project’s actual safety and heating requirements.
Can I simply eliminate backup heat?
Not solely to fit an electrical panel. Backup strategy should be based on equipment capacity, building load, climate and homeowner needs.
Does dual fuel need less electrical capacity?
It can require less electric backup capacity because the gas furnace provides alternate heating, but the heat pump and furnace still require electrical power.
Will my gas furnace work during a power outage?
Most modern forced-air gas furnaces require electricity for controls, ignition and the blower, so retaining a furnace does not automatically provide heating during an outage.
Does switching from gas to a heat pump increase electrical load?
Yes, because space heating moves partly or fully onto electricity. The size of the increase depends on the heat pump and backup-heating design.
Does switching from electric baseboards to a heat pump increase electrical load?
Not necessarily. The home already has resistance-heating loads, and a heat pump can require less electricity to provide the same useful space heat under normal operation.
Can baseboard circuits be reused for a heat pump?
Do not assume so. The new equipment circuit must meet its own electrical requirements.
Should I remove old baseboard breakers after installing a heat pump?
Only according to the final heating and electrical design. Some baseboards may remain as supplementary or backup heating.
Does an air-to-water heat pump require more electrical planning?
It can. Pumps, hydronic modules, electric backup and replacement domestic water-heating equipment can all add electrical loads.
Can a heat pump water heater affect whether I need 200 amps?
It is another electrical load that should be included in the complete home assessment, particularly when installed as part of a broader gas-to-electric conversion.
What about an EV charger?
EV charging can be a large flexible electrical load and should be considered when designing heat pump electrification.
Do I need 200 amps for a heat pump and EV charger?
Not automatically. Professional load calculation and approved load-management strategies may allow some homes to use the existing service.
Can EV load management help?
Yes in appropriate installations. Charging can often be reduced or paused during other high electrical demand.
Can a smart electrical panel avoid a service upgrade?
Potentially. BC Hydro currently identifies smart panels and load-management technologies as tools that may help some electrification projects avoid or defer service upgrades.
Does a smart panel create more electrical capacity?
No. It manages how available capacity is used.
What is a load-share device?
It is a control arrangement that coordinates electrical loads to prevent selected equipment from operating simultaneously beyond the designed capacity.
Can load sharing be used with a heat pump?
Possibly, but essential heating operation, equipment requirements and applicable electrical rules need to be respected.
Should my heat pump be switched off when my EV charges?
That would normally be a poor comfort strategy. Flexible loads such as vehicle charging are generally better candidates for management than essential winter heating.
How does an electrician determine whether I have enough capacity?
The electrician evaluates the service, existing loads, applicable demand calculations and the proposed new equipment.
Can BC Hydro usage data help?
Yes. BC Hydro currently provides home electrical-capacity data and says historical meter information may support professional load calculations where appropriate.
Is monthly electricity consumption enough to size the service?
No. Electrical service design also considers peak and simultaneous demand.
Why does simultaneous load matter?
Several large appliances operating at once can create high instantaneous demand even when total monthly electricity consumption is moderate.
Can I calculate the load myself by adding breaker sizes?
No. Adding every breaker rating does not represent the required electrical load calculation.
Can an electrician use my historical peak load?
Historical meter data can be useful in approved assessment methods. The electrician determines which method is applicable.
What happens if the home does need a service upgrade?
The project may involve the utility connection, service conductors, panel, meter base, mast or conduit, permits and inspections depending on the property.
How long does a service upgrade take?
There is no universal timeline. Contractor availability, utility coordination, permit work and site conditions all affect scheduling.
Should the service upgrade happen before the heat pump?
The sequence should be coordinated so required electrical capacity is available when the equipment is commissioned and existing heating is not removed prematurely.
Does BC currently have an electrical service upgrade rebate?
Yes. The CleanBC Better Homes Energy Savings Program currently includes an electrical service upgrade rebate for eligible participants converting qualifying fossil-fuel primary space and/or water heating to a heat pump through the program.
How much is the current electrical service upgrade rebate?
For the current Energy Savings Program requirements effective for invoices dated on or after July 6, 2026, the maximum is up to $5,000 for Income Level 1, $3,500 for Income Level 2 and $1,500 for Income Level 3, subject to eligible project costs and all program requirements.
Does a panel upgrade alone qualify for that rebate?
No. The current electrical service upgrade rebate requires a utility service upgrade. Panel or sub-panel work without the utility service upgrade is not eligible for that specific rebate.
Can an electric-baseboard homeowner get the electrical service upgrade rebate?
The current Energy Savings Program electrical service upgrade rebate is specifically for eligible conversions from fossil-fuel primary space and/or water heating to a heat pump.
Does the utility need to be involved?
Yes for the qualifying current service-upgrade rebate. The utility must upgrade the electrical service connection according to the program requirements.
Does the service upgrade have to happen at the same time as the heat pump?
The current program requires the qualifying service upgrade to be installed within six months of the heat pump installation.
Do I need a Registered Contractor for the current service-upgrade rebate?
Yes. Current Energy Savings Program rules require the work to be purchased, supplied and installed by a Registered Contractor approved for electrical service upgrades under the program.
Does a heat pump need an electrical permit in BC?
Technical Safety BC states that most residential heat pump installations or upgrades require an electrical permit.
Who normally gets the electrical permit?
When you hire a licensed contractor to perform the regulated work, Technical Safety BC states that the contractor applies for the applicable permit on your behalf.
Can a homeowner apply for a permit?
Technical Safety BC has homeowner permit pathways, subject to eligibility conditions. Hiring a contractor does not mean the homeowner should take out the permit for the contractor’s work.
Does gas-furnace removal need another permit?
Yes, applicable gas work and gas-permit requirements apply when regulated natural gas equipment is modified or removed.
Who can perform heat pump electrical work in BC?
The regulated electrical work must be performed under the qualifications and licensed-contractor requirements identified by Technical Safety BC.
Can the HVAC technician do the electrical work?
Only when the individual holds the applicable electrical qualification, or qualifying refrigeration electrical credential, and performs the work under the required licensed contractor or operating-permit structure.
Can a heat pump be installed before the electrical permit is arranged?
The regulated work should follow the applicable permit process. Permit responsibility should be established before installation begins.
What electrical information should appear on the heat pump quote?
The quote should identify new circuits, breakers, disconnects, panel or service work, permits, utility work and whether load management is included.
Should the HVAC quote include electrical service-upgrade cost?
If a service upgrade is required, the proposal should make clear whether that work is included, separately quoted or subject to further electrical assessment.
What is the biggest electrical planning mistake?
Ordering the heat pump and backup heater before checking whether the complete home electrical system can support the design.
Does Bernoulli provide free installation estimates?
Bernoulli Heating and Cooling currently provides free estimates for new heat pump installation projects across Metro Vancouver and Fraser Valley.
How much is diagnosis for an existing heat pump electrical problem?
Bernoulli Heating and Cooling currently charges $135 for a diagnostic appointment on an existing heat pump. Required repair labour, replacement parts, materials, refrigerant and electrical work are separate.
