Updated July 27, 2026: Electricity and natural gas rates change over time. The BC Hydro and FortisBC figures in this guide reflect published rates available in July 2026. Check current utility rates before using them for a long-term heating-cost comparison.
Heat pump operating cost in BC depends on much more than the size of the outdoor unit. Electricity rates, outdoor temperature, home heat loss, heat pump efficiency, equipment sizing, thermostat settings, ductwork and backup heating can all change what a homeowner ultimately pays.
A properly selected heat pump can move several units of heat into a home for each unit of electricity it consumes. That is why heat pumps generally use much less electricity for space heating than electric resistance systems such as baseboards or electric furnaces.
However, there is no responsible universal claim that a heat pump will cost a specific amount per month for every BC home. A small well-insulated townhouse in Burnaby and a large older detached house with significant heat loss may use dramatically different amounts of electricity even with similar equipment.
This guide explains how to estimate heat pump running costs, how current BC Hydro residential rates affect the calculation, when auxiliary heat matters and how to compare a heat pump with electric resistance or natural gas heating.
How Much Does a Heat Pump Cost to Run in BC?
There is no single monthly or annual number that applies to every home.
Heat pump operating cost can change substantially based on:
- Home heating and cooling load
- Outdoor temperature
- Heat pump efficiency
- Low-temperature performance
- Equipment capacity
- Electric backup heat
- Thermostat setpoint
- Duct and airflow losses
- BC Hydro rate plan
The Most Important Number Is Electricity Consumption
A heat pump’s operating cost starts with the amount of electricity it consumes, measured in kilowatt-hours or kWh.
The basic calculation is:
Heat pump electricity use in kWh × applicable electricity rate = energy charge
Actual utility bills can also include:
- Basic charges
- Rate riders
- Taxes
- Other applicable fees
That means a simple kWh calculation estimates the energy portion of the bill rather than every charge on the utility statement.
How Is Heat Pump Operating Cost Calculated?
There are two useful ways to think about operating cost.
Method 1: Use Actual Electricity Consumption
If you already have a heat pump, compare household electricity use before and after installation using BC Hydro consumption history.
For the best comparison, also consider:
- Weather
- Number of billing days
- Thermostat settings
- Occupancy
- Other electrical loads
Method 2: Estimate From Heating Demand and Efficiency
For planning before installation, the heating demand of the home can be combined with estimated seasonal heat pump efficiency.
A simplified relationship is:
Required heat ÷ heat pump efficiency = approximate electrical energy required
For example, if the home needs a given amount of heat and the heat pump operates at an average coefficient of performance of 3 under those conditions, approximately one unit of electricity is required for every three units of heat delivered.
This Is Still an Estimate
Actual seasonal electricity use also includes:
- Defrost
- Indoor and outdoor fans
- Standby power
- Backup heat
- Changing outdoor conditions
- Control strategy
That is why one laboratory COP value should never be converted directly into a guaranteed annual utility bill.
BC Hydro Residential Electricity Rates in 2026
As of April 1, 2026, BC Hydro residential customers can choose between tiered and flat electricity rate structures. Optional Time-of-Day pricing can also be added to either plan.
Tiered Residential Rate
| Charge | 2026 Rate |
|---|---|
| Tier 1 energy | 11.87 cents per kWh |
| Tier 2 energy | 14.08 cents per kWh |
| Tier 1 threshold, typical 30-day billing period | 675 kWh |
| Tier 1 threshold, typical 60-day billing period | 1,350 kWh |
| Basic charge | 23.44 cents per day |
The actual Tier 1 threshold is prorated based on billing days.
Review current information on the official BC Hydro residential tiered rate page.
Residential Flat Rate
BC Hydro’s residential flat rate currently charges:
- 12.70 cents per kWh for electricity use
- 25.00 cents per day as the basic charge
The energy rate does not increase when electricity consumption moves above a tier threshold.
BC Hydro notes that this option may suit households with higher electricity consumption, including detached houses, townhouses and duplexes using electric heating.
Review the official BC Hydro flat rate information.
Which Rate Is Better for a Heat Pump Home?
It depends on the complete household consumption pattern.
A heat pump owner who remains mostly within Tier 1 may benefit differently from a large full-electric home that regularly uses substantial Tier 2 electricity.
BC Hydro provides a rate estimator using the customer’s actual consumption history. That is more useful than assuming every heat pump owner should choose the same rate plan.
Factor 1: Heat Pump COP
Coefficient of Performance, or COP, describes the relationship between heat delivered and electricity consumed under a specific operating condition.
Example
A COP of 3 means that, under the tested condition, the heat pump delivers approximately three units of heat for each unit of electrical energy used by the heat pump.
Natural Resources Canada defines COP as the ratio between the rate of thermal energy transferred by the heat pump and the electrical power required to move that heat.
COP Changes
COP is not fixed throughout the winter.
It can change with:
- Outdoor temperature
- Indoor temperature
- Compressor speed
- Defrost
- Supply-water or air temperature where applicable
- Equipment design
Do Not Compare Heat Pumps From One COP Number
A COP published at one mild outdoor temperature does not show complete winter performance.
Review performance across the temperatures relevant to the home and local climate.
Natural Resources Canada provides detailed information on heat pump efficiency and seasonal performance.
Factor 2: Seasonal Efficiency Matters More Than One Test Point
A homeowner pays for electricity across the entire heating season, not one laboratory hour.
Seasonal Efficiency Accounts for Changing Conditions
Heat pump output and efficiency change as:
- Weather changes
- Home heating load changes
- Compressor capacity changes
- Defrost occurs
- Backup heat operates
HSPF and HSPF2
Seasonal heating performance metrics attempt to represent heat delivered compared with electricity consumed over a heating season.
However, published rating conditions do not perfectly reproduce every BC home or climate.
Low-Temperature Performance Is Important in Canada
When comparing heat pumps for BC, review:
- Heating capacity at lower temperatures
- COP at lower temperatures
- Minimum operating temperature
- Supplementary heat strategy
A model with an attractive headline efficiency number can still have very different winter performance from another system.
Factor 3: Outdoor Temperature Changes Heat Pump Operating Cost
Heating energy demand generally increases as outdoor temperature drops.
Two things happen at the same time:
- The home loses heat faster.
- The heat pump may operate at a different efficiency and capacity.
Mild BC Winter Conditions
During milder weather, the home requires less heating and the heat pump can often operate at reduced capacity.
Cold Weather
During colder conditions:
- Heating load increases
- Heat pump runtime can increase
- Compressor capacity can increase
- Defrost may occur
- Supplementary heating may be required
Climate Within BC Is Not Uniform
A system in Metro Vancouver does not experience the same winter conditions as a system in colder interior or northern BC locations.
Operating-cost estimates should therefore use local climate data rather than a generic Canada-wide number.
Factor 4: The Home’s Heating Load Can Matter More Than the Brand
The heat pump can only respond to the amount of heat the building loses.
Heat Loss Is Affected By:
- Home size
- Insulation
- Air leakage
- Windows
- Doors
- Ceiling height
- Basement conditions
- Building orientation
Two Identical Heat Pumps Can Have Different Bills
Consider two homes using the same equipment.
Home A has:
- Upgraded attic insulation
- Good windows
- Lower air leakage
Home B has:
- Older windows
- Limited insulation
- Significant drafts
Home B needs more heat every winter hour, so the same heat pump must consume more energy to maintain the same indoor temperature.
Start With the Load Calculation
A proper heat pump design should estimate the home’s heating and cooling loads before equipment capacity is selected.
This provides a much better foundation for operating-cost estimates than floor area alone.
Factor 5: Thermostat Settings Affect Operating Cost
A warmer winter setpoint means the home loses heat faster to the outdoors.
A lower summer cooling setpoint increases cooling demand.
Large Setbacks Can Affect Backup Heat
Heat pumps often work efficiently while maintaining a relatively steady indoor temperature.
If the thermostat is reduced significantly overnight and then raised several degrees in the morning, some systems may call for supplementary electric heat to recover more quickly.
ENERGY STAR Heat Pump Guidance
ENERGY STAR recommends choosing a comfortable temperature and keeping it relatively steady rather than using large routine setbacks with heat pumps.
Review the official ENERGY STAR heat pump operating guidance.
Do Not Set the Thermostat Higher to Make Heating Faster
Increasing the setpoint significantly does not make the heat pump magically develop a larger compressor.
It can instead create a longer demand and, on some systems, activate supplementary heating.
Factor 6: Electric Auxiliary Heat Can Change Winter Cost Significantly
This is one of the most important differences between heat pump installations.
Electric resistance auxiliary heat has a different operating efficiency from compressor heat-pump heating.
Heat Pump Compressor Heating
A heat pump moves heat and can deliver multiple units of heat for each unit of electricity consumed.
Electric Resistance Backup
Resistance heaters convert electrical energy directly into heat.
They therefore require substantially more electricity than a heat pump operating at a COP well above 1 to deliver the same amount of heat.
Backup Heat May Operate During:
- Cold outdoor conditions
- Defrost
- Large thermostat recovery
- Heat pump failure
- Peak heating demand
AUX Heat Is Not Automatically Bad
Supplementary heat can be an intended part of the system design.
The concern is whether it runs more often than the design requires.
For Operating-Cost Estimates, Ask:
- What is the heat pump capacity at the local winter design temperature?
- How much backup capacity is installed?
- When is the backup expected to run?
- Is the backup electric or gas?
Ignoring backup heating can make an operating-cost estimate look wonderfully cheap right up until winter arrives and reality sends the invoice.
Factor 7: Ductwork and Airflow Affect the Cost of Delivered Comfort
A heat pump can produce heat efficiently and still waste energy if the distribution system performs poorly.
Duct Problems Can Include:
- Air leakage
- Poor attic insulation
- Restricted return air
- Undersized ducts
- Crushed flexible duct
- Poor balancing
Duct Leakage
If heated air escapes into an attic, crawl space or garage, the heat pump must run longer to replace that lost heat.
High Static Pressure
Restricted ductwork can reduce airflow and make blower and heat pump performance less effective.
ENERGY STAR identifies proper airflow and duct evaluation as important parts of HVAC quality installation.
See the official ENERGY STAR quality installation guidance.
Factor 8: Heat Pump Sizing Affects Operating Cost
Correct sizing is not simply about whether the system can heat the home.
It also affects how the equipment operates throughout the year.
Oversized Heat Pump
A significantly oversized system may:
- Cycle more frequently
- Spend more time in startup and shutdown transitions
- Provide poorer humidity control during cooling
- Operate less effectively during mild weather
Undersized Heat Pump
An undersized system may:
- Run at maximum capacity for long periods
- Fail to maintain temperature during peak conditions
- Use supplementary heat more often
The Objective Is Not the Biggest Heat Pump
The equipment should be selected from:
- Calculated heating load
- Calculated cooling load
- Local climate
- Low-temperature heat pump capacity
- Backup strategy
- Duct airflow
Natural Resources Canada provides a Canadian air-source heat pump sizing and selection toolkit for this process.
Factor 9: Equipment Condition and Maintenance Affect Efficiency
A heat pump that was efficient when installed can gradually operate less effectively if airflow or heat transfer deteriorates.
Common Maintenance-Related Issues Include:
- Dirty filters
- Dirty indoor coil
- Dirty outdoor coil
- Dirty blower wheel
- Blocked outdoor airflow
- Refrigerant problems
Dirty Filters
A restricted filter increases airflow resistance and can contribute to longer operating times or abnormal coil conditions.
Dirty Coils
Coil contamination reduces heat transfer and can increase equipment runtime.
Refrigerant Charge
A sealed heat pump should not routinely need refrigerant added.
A low charge can indicate a leak and reduce system performance.
ENERGY STAR Maintenance Guidance
ENERGY STAR recommends professional HVAC maintenance that includes controls, electrical connections, condensate drainage, coils, refrigerant condition, blower components and filters.
Review the official ENERGY STAR maintenance checklist.
Factor 10: Summer Cooling Adds Electricity Use
A heat pump provides two services: heating and cooling.
This matters when comparing annual energy bills.
Replacing a Furnace
A gas furnace may have provided no summer cooling.
After installing a heat pump, the family may begin maintaining comfortable indoor temperatures throughout the summer.
Annual electricity use can therefore increase because the home is receiving a service it did not previously have.
That Is Not Necessarily Reduced Efficiency
Comparing annual electricity use before and after installation without accounting for new summer cooling can give a misleading result.
Cooling Cost Depends On:
- Summer temperature
- Sun exposure
- Window area
- Thermostat setpoint
- Indoor humidity
- Cooling hours
Factor 11: Your BC Hydro Rate Plan Can Change the Dollar Cost
The same number of heat pump kWh can have a different cost under different residential rate structures.
Tiered Rate
Consumption above the Tier 1 threshold is currently charged at the higher Tier 2 rate.
A larger full-electric house may cross that threshold more frequently than a small condo.
Flat Rate
The flat rate applies the same energy charge to all kWh and may be attractive to some higher-consumption households.
Do Not Choose From the Heat Pump Alone
The rate applies to total household consumption, which can include:
- Heat pump
- Electric water heater
- EV charging
- Cooking
- Laundry
- Lighting
- Other electrical equipment
Use Your Actual Consumption History
BC Hydro provides a rate estimator to compare rate options based on the customer’s historical electricity use.
Review current options on the official BC Hydro residential rates page.
Factor 12: The Heat Pump Is Not the Entire Utility Bill
A common mistake is assigning the complete electricity bill to the heat pump.
Other Major Electric Loads Can Include:
- Electric water heating
- EV charging
- Baseboard heaters
- Portable space heaters
- Hot tub
- Clothes dryer
- Electric range
- Secondary refrigerators or freezers
Baseboards Can Remain Active After Heat Pump Installation
In some retrofit homes, existing baseboards remain installed for backup or individual rooms.
If their thermostats remain set high, they can operate at the same time as the heat pump.
Use Consumption Data
BC Hydro’s online tools can help homeowners compare consumption across days and hours rather than trying to diagnose equipment from the total dollar amount alone.
Heat Pump Operating Cost Example Using BC Electricity Rates
The following example is educational only. It is not an estimate for a specific home.
Assume a home needs 10,000 kWh of useful space heat over a given period.
If Average COP Were 2
Approximate heat pump electricity:
10,000 ÷ 2 = 5,000 kWh
At the current BC Hydro flat energy rate of 12.70 cents per kWh:
Approximate energy charge: $635
If Average COP Were 3
Approximate heat pump electricity:
10,000 ÷ 3 = approximately 3,333 kWh
At 12.70 cents per kWh:
Approximate energy charge: $423
If Average COP Were 4
Approximate heat pump electricity:
10,000 ÷ 4 = 2,500 kWh
At 12.70 cents per kWh:
Approximate energy charge: $317.50
What This Example Does Not Include
- BC Hydro basic charge
- Rate riders
- Taxes
- Backup electric heat
- Fans
- Defrost
- Cooling
- Other household electricity
Why This Example Matters
The same heating load can require very different electricity consumption depending on the heat pump’s seasonal operating efficiency.
It also shows why quoting a monthly heat pump bill without knowing the home load and system performance is mostly fortune-telling with an HVAC logo attached.
Heat Pump vs Electric Baseboard Operating Cost
Electric resistance baseboards convert electricity directly into heat at the point of use.
A heat pump transfers heat and can therefore deliver more useful heat per unit of electricity under normal operating conditions.
NRCan Comparison
Natural Resources Canada states that cold-climate air-source heat pumps can provide space heating up to approximately 2.5 times more efficiently than electric resistance equipment such as baseboards or electric furnaces.
What That Means for a Homeowner
If electric baseboards currently provide most of the home’s heating, a correctly designed heat pump can substantially reduce the electricity required for space heating.
Savings Still Depend On:
- Heat pump efficiency
- Outdoor climate
- Indoor setpoint
- How much of the home the heat pump serves
- Whether baseboards continue operating
Ductless Retrofits
Homes without central ducts often use ductless heat pumps to reduce baseboard use while maintaining existing baseboards as supplementary heating where required.
Heat Pump vs Electric Furnace Operating Cost
An electric furnace uses resistance heating to create heat, while an air-source heat pump moves heat into the building.
The Heating Load Is the Same
The home still needs a certain amount of heat to remain comfortable.
The difference is how much electricity each system needs to supply that heat.
Example Principle
If a heat pump operates at a seasonal efficiency substantially above a COP of 1, it can require much less electricity than pure electric resistance heating for the same useful heat output.
Backup Heat Still Matters
A full-electric central heat pump may include resistance auxiliary heat.
If that backup runs extensively, total electricity use moves closer to electric resistance heating for those hours.
Heat Pump vs Gas Furnace Operating Cost in BC
This comparison is more complicated because electricity and natural gas use different units and rate structures.
Do Not Compare 12.70 Cents per kWh With the Cost-of-Gas Number Alone
A residential FortisBC gas bill includes multiple components.
As of July 1, 2026, Mainland and Vancouver Island residential rates include:
- Basic daily charge
- Delivery charge
- Storage and transport charge
- Cost of gas
The current published rates are:
| FortisBC Residential Charge | Rate Effective July 1, 2026 |
|---|---|
| Basic charge | $0.4216 per day |
| Delivery charge | $8.469 per GJ |
| Storage and transport | $2.472 per GJ |
| Cost of gas | $1.660 per GJ |
Other applicable fees, taxes or program-related amounts can also affect the bill.
Review the latest FortisBC residential natural gas rates before performing a current comparison.
Furnace Efficiency Also Matters
A gas furnace does not deliver every unit of fuel energy into the home as useful space heat.
The actual comparison should consider:
- Gas consumption
- Furnace efficiency
- All variable gas charges
- Fixed gas charges
- Heat pump seasonal efficiency
- Electricity rate
Keeping the Gas Connection Changes the Economics
If the home retains natural gas for:
- Water heating
- Fireplace
- Cooking
- Furnace backup
the fixed gas-account charges remain even if the heat pump reduces furnace runtime.
NRCan Canadian Research
Natural Resources Canada has modelled cold-climate heat pump and hybrid operating costs across multiple Canadian housing types and climates.
The results show why gas-versus-heat-pump cost cannot be reduced to one Canada-wide percentage. Home efficiency, climate, utility rates and whether the gas connection remains all affect the result.
Dual-Fuel Heat Pump Operating Cost
A dual-fuel system uses both a heat pump and gas furnace.
The controls determine which system provides heat under different conditions.
Operating Cost Depends on the Changeover Strategy
The system may prioritize the heat pump during milder outdoor conditions and use the furnace under selected colder conditions.
Possible Changeover Objectives Include:
- Lowest operating cost
- Maintaining heating capacity
- Reducing electrical peak load
- Comfort preference
The Best Changeover Point Is Not Universal
It depends on:
- Heat pump COP at the current outdoor temperature
- Gas furnace efficiency
- Electricity price
- Gas price
- Home heating load
Evaluate Both Utility Bills
A dual-fuel system may increase electricity consumption while reducing natural gas consumption.
Comparing only the electricity bill can therefore make the system appear more expensive even when total space-heating cost has changed differently.
Ductless Heat Pump Operating Cost
Ductless systems avoid central duct losses but their operating cost still depends on how they are used.
A Single-Zone System
A single indoor unit may provide efficient heating and cooling to:
- Living area
- Basement suite
- Addition
- Open-concept floor
Whole-Home Multi-Zone System
Operating cost increases as more of the building’s heating load is served.
This is not necessarily an efficiency problem. The system is simply providing more heating.
Room Setpoints Matter
A homeowner who previously heated bedrooms minimally with baseboards but now keeps every ductless zone at 22°C may gain comfort while using more energy than expected.
Keep Filters and Blowers Clean
Ductless indoor units rely on clean filters, coils and blower wheels for proper airflow.
Central Ducted Heat Pump Operating Cost
A central heat pump conditions the home through a duct system.
Advantages Can Include:
- Whole-home distribution
- Central filtration
- Integration with existing furnace
- Fewer visible indoor units
Operating Cost Is Closely Tied to Duct Performance
The system may use more electricity than expected when:
- Return airflow is restricted
- Supply ducts leak
- Attic ducts are poorly insulated
- Blower settings are incorrect
- Rooms are badly balanced
Do Not Ignore the Existing Furnace Ducts
A new high-efficiency outdoor unit cannot overcome severe duct restrictions.
Central installation planning should include airflow and static-pressure evaluation.
For a local example of this planning approach, see Heat Pump Installation Burnaby.
Full-Electric Heat Pump Operating Cost
A full-electric heat pump system eliminates or substantially reduces dependence on combustion heating for the served space.
Annual Electricity Use Can Increase
This is expected when electricity replaces:
- Natural gas
- Oil
- Propane
The correct question is whether total household energy cost and consumption changed as expected, not whether the electricity bill alone became larger.
Electric Backup Is Important
Full-electric central systems may include electric supplemental heating for:
- Peak conditions
- Defrost
- Emergency operation
The load calculation and equipment selection should minimize unnecessary reliance on backup while still providing the required heating capacity.
Electrical Rate Selection Can Matter More
A full-electric detached home may use enough electricity that comparing BC Hydro’s tiered and flat plans becomes worthwhile.
Does a Heat Pump Running All Day Cost More?
Runtime alone does not tell you how much electricity the heat pump is using.
Variable-Capacity Heat Pumps
Modern inverter heat pumps can:
- Run for long periods
- Reduce compressor speed
- Lower fan speed
- Match output more closely to the building load
A system running for eight hours at low capacity can use less electricity than a system repeatedly operating at much higher output.
Long Runtime Can Be Normal
It is especially common during colder weather when heating demand is continuous.
Long Runtime Needs Investigation When:
- The home cannot maintain temperature
- Electric backup runs continuously
- Fault codes appear
- Heating output has declined
- Outdoor unit is heavily iced
Does a Heat Pump Cost More to Run When It Gets Colder?
Generally, yes.
The building requires more heat as outdoor temperature falls.
Cold Weather Can Increase:
- Compressor runtime
- Compressor output
- Defrost frequency
- Supplementary heating
This Does Not Mean Heat Pumps Stop Working in Cold Weather
Cold-climate equipment is specifically designed for winter operation.
The important questions are:
- What capacity does the model provide at low temperature?
- What is its efficiency at that temperature?
- What is the home’s heat loss?
- When does backup heat operate?
Compare Published Performance, Not Marketing Labels
Two products both described as cold-climate heat pumps may have different:
- Low-temperature capacity
- COP
- Minimum operating temperature
- Backup requirements
Can BC Hydro Time-of-Day Pricing Reduce Heat Pump Cost?
Possibly, but it is not automatically the best plan for every heat pump home.
Current Time-of-Day Structure
BC Hydro currently applies:
- 5 cents per kWh discount from 11 p.m. to 7 a.m.
- 5 cents per kWh surcharge from 4 p.m. to 9 p.m.
- No adjustment during other hours
The option can be added to either the residential tiered or flat rate.
See the current BC Hydro Time-of-Day pricing information.
Space Heating Is Not as Flexible as EV Charging
A homeowner can schedule an EV to charge after 11 p.m.
Space heating cannot always be moved away from 4 p.m. to 9 p.m. because the home may genuinely need heat during those hours.
Large Setbacks Can Backfire
Turning the heat pump down aggressively during higher-priced hours and then forcing a large recovery later can affect comfort and may activate backup heat.
Use the BC Hydro Rate Estimator
The best decision is based on actual household hourly electricity use rather than assuming overnight discounts will automatically reduce heating costs.
How Can You Estimate Your Own Heat Pump Operating Cost?
Before Installation
Ask the contractor for:
- Home heat-load calculation
- Proposed heat pump model
- Low-temperature capacity data
- Expected backup heating strategy
- Ductwork or zoning plan
Review Existing Energy Use
Gather previous:
- BC Hydro bills
- FortisBC bills
- Oil or propane purchases where applicable
Use Comparable Periods
Compare energy use over similar winter conditions rather than comparing a mild November with a cold January.
After Installation
Track:
- Monthly kWh
- Daily kWh
- Outdoor temperature
- AUX heat runtime
- Thermostat settings
For Fuel-Switching Projects
Compare total energy costs:
Before: electricity + gas or other heating fuel
with:
After: electricity + any remaining gas or other fuel
This gives a more useful picture than comparing electricity bills alone.
How Can BC Homeowners Reduce Heat Pump Operating Cost?
Use a Reasonable, Steady Setpoint
Avoid large routine temperature swings that may trigger unnecessary backup heating.
Keep Filters Clean
Restricted airflow can reduce heat pump performance.
Keep the Outdoor Unit Clear
Remove loose leaves, vegetation and snow that interfere with airflow while maintaining manufacturer clearances.
Do Not Block Registers and Returns
Closing many registers can increase duct static pressure and reduce airflow.
Maintain the Equipment
Address:
- Dirty coils
- Airflow problems
- Refrigerant leaks
- Sensor faults
- Excessive defrost
Reduce Building Heat Loss
Improvements such as:
- Air sealing
- Attic insulation
- Improved windows
- Door sealing
can reduce the amount of heat the HVAC system needs to provide.
Review Your BC Hydro Rate Plan
Homes with higher electricity use may benefit from comparing tiered and flat rates using actual utility history.
Check Unexpected AUX Heat Use
If electric resistance backup runs frequently during relatively mild weather, thermostat settings, heat pump operation, equipment capacity and controls may need evaluation.

Heat Pump Operating Cost in BC: Frequently Asked Questions
How much does a heat pump cost to run per month in BC?
There is no universal monthly cost. Home heat loss, outdoor weather, equipment efficiency, backup heat, thermostat settings and electricity rate all affect consumption.
How do I calculate my heat pump running cost?
Multiply the heat pump’s electricity consumption in kWh by the applicable electricity energy rate. Utility basic charges, rate riders, taxes and other household loads should be considered separately.
What is the BC Hydro residential electricity rate in 2026?
As of April 1, 2026, the residential tiered rate charges 11.87 cents per kWh in Tier 1 and 14.08 cents per kWh in Tier 2. The residential flat energy rate is currently 12.70 cents per kWh.
How much electricity can I use before BC Hydro Tier 2?
For a typical 30-day billing period, the Tier 1 threshold is 675 kWh. For a typical 60-day billing period, it is 1,350 kWh. BC Hydro prorates the threshold based on billing days.
Is BC Hydro’s flat rate better for a heat pump?
It may be better for some higher-consumption households, but not all. Use BC Hydro’s rate estimator with your actual consumption history.
Does a heat pump use less electricity than electric baseboards?
Usually yes. Heat pumps move heat rather than producing all heating through electric resistance, allowing them to deliver more heat per unit of electricity under normal operation.
Does a heat pump use less electricity than an electric furnace?
Generally yes for compressor heat-pump heating. Electric furnaces use resistance heating, while heat pumps can operate at a COP substantially above 1.
What is COP?
COP is the ratio of heat delivered by the heat pump to electrical power consumed under a specific operating condition.
Is a COP of 3 good?
A COP of 3 means the heat pump delivers approximately three units of heat for every unit of electricity used under that specific condition. COP changes with outdoor temperature and system operation.
Does COP stay the same all winter?
No. It changes with outdoor temperature, compressor output, indoor conditions and defrost operation.
What is HSPF?
HSPF is a seasonal heating-efficiency metric that compares heating delivered with electricity used over a representative heating season.
Does a heat pump cost more to run when it gets cold?
Usually yes because the home requires more heat, compressor demand increases and supplementary heating may operate.
Does a heat pump become inefficient below freezing?
Efficiency generally changes as temperature falls, but modern cold-climate heat pumps are designed to continue providing heating below freezing. Performance varies by model.
Does a heat pump stop working at 0°C?
No. Air-source heat pumps are designed to operate below 0°C. Exact capacity, efficiency and minimum operating temperature depend on the equipment.
Does defrost increase operating cost?
Defrost uses energy and temporarily redirects heating to the outdoor coil. Some systems also use supplementary heat during defrost.
Does AUX Heat cost more than the heat pump?
When AUX is electric resistance heating, it generally requires more electricity for the same useful heat than compressor heat-pump operation at a COP above 1.
Why is my AUX Heat running?
It may operate during cold conditions, defrost, large temperature recovery or when heat-pump capacity is insufficient.
Is AUX Heat bad?
No. It can be a normal part of the system. Excessive operation outside expected conditions is what should be investigated.
Does Emergency Heat cost more?
If Emergency Heat uses electric resistance heating, extended operation can use substantially more electricity than normal heat-pump compressor heating.
Should I turn my thermostat down at night?
Large setbacks can create a high recovery demand and may activate supplemental heat. Heat pumps often operate efficiently with relatively steady temperature settings.
Does setting my heat pump to 24°C cost more than 20°C?
Generally yes during heating because the larger indoor-to-outdoor temperature difference increases building heat loss.
Does a heat pump running constantly cost a lot?
Runtime alone does not determine electricity use. Variable-capacity systems can operate for long periods at low compressor output.
Is it cheaper for a heat pump to run continuously or cycle?
The system should operate according to its designed controls. Variable-capacity heat pumps often use long low-output cycles efficiently, while unnecessary short cycling can reduce performance.
Can an oversized heat pump cost more to run?
Oversizing can create frequent cycling and poor low-load operation. Equipment should be selected from the home’s calculated load.
Can an undersized heat pump cost more to run?
An undersized system may operate at high output for long periods and use supplementary heating more frequently during peak conditions.
Can bad ductwork increase heat pump operating cost?
Yes. Duct leakage, poor insulation and excessive static pressure can increase runtime and reduce useful heat delivered to occupied rooms.
Can a dirty filter increase operating cost?
Yes. Restricted airflow can make the system work harder and reduce heating or cooling performance.
Can dirty coils increase electricity use?
Yes. Dirt reduces heat transfer and can increase equipment runtime.
Can low refrigerant make a heat pump expensive to run?
Yes. A refrigerant problem can reduce capacity and efficiency, causing longer operation or additional backup heating.
Does a heat pump need refrigerant added every year?
No. Refrigerant circulates in a sealed system. A low charge indicates a leak, commissioning problem or unresolved previous repair.
Is a ductless heat pump cheaper to run than a central heat pump?
There is no universal answer. Ductless systems avoid central duct losses, but cost depends on zone loads, equipment efficiency, temperatures and how many areas are conditioned.
Does adding more mini-split heads increase electricity use?
It can when the additional heads are used to heat or cool more of the home. Greater comfort and greater conditioned area naturally require more energy.
Is a full-electric heat pump expensive to run?
Cost depends on heat pump efficiency, home load, outdoor weather and use of electric supplementary heat. Electricity consumption should be compared with the fuel costs the system replaces.
Why did my electricity bill increase after switching from gas to a heat pump?
The heating load moved partly or entirely from the gas bill to the electricity bill. Compare total energy costs rather than electricity alone.
Is a heat pump cheaper to operate than a gas furnace in BC?
It depends on heat pump efficiency, furnace efficiency, current electricity and gas rates, weather, home load and whether the gas connection remains for other appliances.
Why can’t I compare electricity price directly with the FortisBC cost-of-gas rate?
Electricity and gas use different units, equipment efficiencies and billing structures. FortisBC residential bills also include delivery, storage and transport and basic charges.
What are FortisBC residential gas rates in July 2026?
For Mainland and Vancouver Island, the current published residential charges include a $0.4216 daily basic charge, $8.469 per GJ delivery charge, $2.472 per GJ storage and transport charge and $1.660 per GJ cost of gas, before other applicable fees and taxes.
Does dual-fuel reduce operating cost?
It can under some combinations of weather, utility prices and equipment performance. The changeover strategy should be based on the actual heat pump, furnace and home rather than a universal outdoor temperature.
What is the economic balance point?
It is the operating condition where the cost of heat from one heating source becomes comparable with the alternative source. It depends on equipment efficiencies and current energy prices.
Is the economic balance point the same as the heat pump capacity balance point?
No. The economic balance point concerns operating cost. The capacity balance point concerns whether heat pump output matches the building heating load.
Can BC Hydro Time-of-Day pricing save heat pump owners money?
Possibly. It currently offers a 5-cent-per-kWh overnight discount and a 5-cent-per-kWh surcharge from 4 p.m. to 9 p.m. Actual savings depend on when the whole home uses electricity.
Should I turn the heat pump off from 4 p.m. to 9 p.m. on Time-of-Day pricing?
Not necessarily. Space-heating demand cannot always be shifted, and large temperature recovery afterward may reduce comfort or trigger backup heat.
Is Time-of-Day pricing better for EV owners?
BC Hydro notes that it can be particularly useful when flexible loads such as EV charging can be shifted to the overnight discount period.
How can I see when my home uses electricity?
BC Hydro customers can review consumption through their online account and compare usage patterns with weather and thermostat operation.
Can insulation reduce heat pump running cost?
Yes. Reducing heat loss lowers the amount of heating the heat pump must supply.
Can new windows reduce heat pump operating cost?
They can when they reduce overall building heat loss or air leakage, although the actual savings depend on the existing windows and the rest of the building envelope.
Should I improve insulation before installing a heat pump?
Major planned envelope improvements should be considered during heat-load calculations because they can change the capacity the home needs.
Does heat pump maintenance save electricity?
Maintenance can restore performance affected by filters, coils, airflow, controls and other service issues.
How often should I clean heat pump filters?
Inspect them regularly and clean or replace them according to manufacturer instructions and actual condition.
How do I know whether my heat pump is using too much electricity?
Compare consumption with outdoor weather, thermostat settings, previous energy use, backup heat operation and system performance rather than relying only on the dollar bill.
When should high operating cost be investigated?
Arrange diagnosis when consumption increases unexpectedly without a clear change in weather, occupancy or thermostat settings, especially if there is weak heating, heavy AUX use, fault codes, unusual noise or icing.
How much does Bernoulli charge for heat pump diagnosis?
Bernoulli Heating and Cooling currently charges $135 for a diagnostic appointment on an existing heat pump. Repair labour, refrigerant, replacement parts and additional materials are separate.
Does Bernoulli charge for new heat pump installation estimates?
New heat pump installation estimates are currently free.
