What Is Dual Fuel Heating?
A dual fuel heating system blends two heat sources: an electric heat pump and a high-efficiency gas (or propane) furnace. The heat pump handles heat when outdoor temperatures are mild and provides cooling in summer, while the furnace takes over in colder weather. A smart thermostat automatically switches between the two based on temperature conditions, optimizing both comfort and cost-efficiency.
Benefits of Going Dual Fuel in BC
1. Exceptional Efficiency
Heat pumps can achieve efficiencies over 100% by transferring heat rather than generating it. By combining them with a furnace, the overall system can exceed conventional efficiency thresholds.
2. Year-Round Comfort
Enjoy efficient heating during mild periods and reliable furnace backup during cold snaps, plus built-in cooling for hotter months—all automated via thermostat.
3. Greenhouse Gas Emissions Reduction
Dual fuel aligns with BC’s CleanBC goals, helping lower energy use and carbon footprint while ensuring that heating systems meet future efficiency targets.
4. Massive Rebates and Support
FortisBC and other programs offer substantial financial incentives
Other opportunities include dual-fuel programs for non-profits through Pacific Northern Gas offering up to $5,000.
Considerations to Keep in Mind
Upfront Cost
Dual fuel systems typically cost more to install initially, since both a heat pump and a furnace are required. However, rebates and long-term energy savings often offset these costs.
Maintenance Requirements
Combining two technologies may require more nuanced service and diagnostics—suitable HVAC contractors are essential.
Is Dual Fuel Right for You?
Consider the following:
- Location & climate: In areas with frequent sub-zero temperatures (e.g., Northern B.C.), a dual fuel system offers both efficiency and reliability.
- Rebates: Substantial financial incentives can dramatically reduce upfront costs.
- Long-term savings: Energy efficiency translates to lower utility bills over time.
- Maintenance readiness: Ensure you have access to qualified installation and service providers until things like thermostat integration and seasonal check-ups are smooth.
In B.C., dual fuel heating systems are an efficient, comfortable, and increasingly affordable choice—especially with rebate programs and growing industry support. Whether you’re in the milder Lower Mainland or colder interior zones, there’s real potential for energy savings, environmental benefits, and long-term comfort.
