Why This Comparison Matters in BC Right Now
BC's CleanBC plan includes incentives to move homes off natural gas toward electricity, and heat pump manufacturers have invested heavily in consumer marketing. At the same time, FortisBC is promoting high-efficiency gas appliances with its own rebate programs. BC homeowners are caught between conflicting messaging.
This comparison is written by gas boiler specialists — so yes, we have a perspective — but we've tried to give heat pumps a fair hearing. Our goal is to help you make the right decision for your specific home, not to sell you something.
Heating Performance in Vancouver's Climate
Greater Vancouver's relatively mild winters (average January low of 2–4°C) make it one of the best climates in Canada for heat pump performance. Cold-climate air-source heat pumps (the modern variety rated to -25°C) work well in the Lower Mainland — this is not an Alberta situation where heat pump output drops dangerously in -30°C snaps.
Hydronic gas boilers, on the other hand, deliver consistent, radiant heat regardless of outdoor temperature. A boiler pushing 82°C water through in-floor or baseboard hydronic systems delivers exceptional comfort that's hard to replicate with forced-air heat pump systems. If your home has radiant floors or cast-iron radiators, a gas boiler will always outperform a heat pump in comfort terms for that system type.
Upfront Installation Cost
A new high-efficiency gas boiler installation in Metro Vancouver typically runs $5,000–$9,000 installed (including permit, hydronic system work, and commissioning). A properly installed cold-climate heat pump replacing a gas boiler in the same home — including the air handler or duct modifications — typically runs $12,000–$20,000, with additional cost if you're also installing a backup heating system for extreme cold days.
Federal and provincial heat pump incentives (up to $6,500 through CleanBC) narrow the gap, but as of 2025, a gas boiler replacement still has meaningfully lower upfront cost.
Operating Costs: Gas vs Electricity in BC
BC Hydro's rates are among the lowest in North America, which tilts the operating cost comparison toward electricity and heat pumps. A heat pump with a COP (Coefficient of Performance) of 3.0 effectively delivers 3 kWh of heat for every 1 kWh consumed. At BC Hydro's residential rate of approximately $0.12/kWh, that's roughly $0.04 per useful kWh of heat.
FortisBC natural gas at approximately $0.065/GJ (gigajoule) equivalent is competitive, especially in a 95% AFUE condensing boiler. The operating cost difference narrows considerably compared to less hydro-rich provinces. Most BC homeowners comparing the two find the operating cost difference is modest — $200–$400 per year favouring the heat pump in average Metro Vancouver weather.
The carbon story is more complex: BC's electricity grid is 98% renewable, making an electric heat pump essentially carbon-neutral to operate. A gas boiler emits CO₂, even at high efficiency. If environmental impact is your primary driver, the heat pump wins clearly.
When We Recommend Each Option
Choose a gas boiler if: your home has an existing hydronic system (radiant floor, baseboard, radiators); you want lower upfront cost; your primary concern is reliability in cold snaps; or you are not ready for a full HVAC overhaul.
Choose a heat pump if: your home has existing ductwork for forced air; you want to reduce your carbon footprint significantly; you're doing a major renovation anyway; or you qualify for the full CleanBC + federal incentive stack.
Choose both: A dual-fuel system (gas boiler backup + heat pump for mild weather) delivers the best of both worlds — heat pump efficiency during Vancouver's mild shoulder seasons, gas reliability during cold snaps. This is increasingly the recommendation for larger homes in the Lower Mainland.
