Electric Furnace Buying Guide & Best Brands in Canada
Introduction
Electric furnaces have become an increasingly popular choice among Canadian homeowners—particularly in areas where natural gas service is limited. As highlighted in our Electric Furnace Buying Guide, they’re dependable, operate cleanly, and eliminate the need for fossil fuels.
This comprehensive guide explores how electric furnaces work, their benefits and limitations, leading brands available in Canada, and what you can expect to pay for purchase and installation. You’ll also learn when an electric furnace might make the most sense for your home and what factors to consider before buying one.
What Is an Electric Furnace and How Does It Work?
An electric furnace is a type of heating system that uses electrical resistance elements to produce heat. Instead of burning natural gas or propane like a conventional furnace, it converts electricity directly into thermal energy.
When your home’s temperature drops below the thermostat setting, an electrical signal activates the furnace. Power flows to the heating elements—typically metal coils made from nickel-chromium—which quickly heat up. A blower motor then pulls cool air from the return ducts, forces it over the hot elements, and circulates the warmed air back through the home’s ductwork.
Once the desired temperature is reached, the system shuts off automatically, though the fan may run briefly to distribute any remaining warm air — a feature commonly noted in our Electric Furnace Buying Guide.
According to Government of Canada recommendations, an electric furnace’s input rate should not exceed 65.92 kW (approximately 225,000 BTU/h) for safe and efficient operation.
Heating and Cooling with an Electric Furnace
While electric furnaces are primarily designed for heating, they can also be integrated into a combined heating and cooling setup.
In a split system, the furnace serves as the indoor air handler for both the heating and cooling process. It works in conjunction with an outdoor condenser (the air conditioner) to distribute cooled air in summer and heated air in winter. Although the furnace itself doesn’t cool the air, it plays a vital role in circulating conditioned air efficiently throughout your home.
Electric Furnace Sizes by Climate Zone
Choosing the right furnace size is essential for maintaining comfort and energy efficiency. As emphasized in our Electric Furnace Buying Guide, undersized furnaces struggle to keep up on cold days, while oversized units cycle on and off too often, wasting power.
Here’s a general guide to furnace output requirements across different climate zones in Canada:
| Home Size (sq ft) | Mild Climate (BTU/hr) | Moderate Climate (BTU/hr) | Cold Climate (BTU/hr) |
| 600 sq ft | 18,000 | 27,000 | 36,000 |
| 1,200 sq ft | 36,000 | 54,000 | 72,000 |
| 1,800 sq ft | 54,000 | 81,000 | 108,000 |
| 2,400 sq ft | 72,000 | 108,000 | 144,000 |
| 3,000 sq ft | 90,000 | 135,000 | 180,000 |
General BTU Guidelines:
- Mild climates: ~30 BTUs per sq ft
- Moderate climates: ~45 BTUs per sq ft
- Cold climates: ~60 BTUs per sq ft
These numbers may vary depending on your home’s insulation, window quality, and air leakage levels.

Electric vs. Gas Furnace Operating Costs
Although electric furnaces are 100% efficient at converting electricity into heat, electricity itself is generally more expensive than natural gas in most provinces.
For instance, producing the same heat output with electricity can cost up to 10 times more than with gas, depending on your utility rates. A mid-sized electric furnace operating 9 hours per day at 18,000 watts could add $500 to $1,000 per month to your hydro bill at Canada’s average $0.192 per kWh rate.
However, in provinces like Quebec, Manitoba, and British Columbia, where electricity is largely hydroelectric and competitively priced, operating costs can be much more reasonable.
Tips to Reduce Electric Heating Costs
- Improve insulation: Sealing leaks and adding insulation reduces energy loss.
- Use off-peak electricity: Some utilities offer discounted night rates.
- Install solar panels: Over time, renewable energy can offset higher electricity costs.
- Consider a heat pump: Heat pumps transfer existing heat rather than creating it, achieving efficiencies over 300%.
When Does an Electric Furnace Make Sense?

Actual costs can vary depending on furnace efficiency, brand, and labour rates.
2. Airflow Capacity (CFM Rating)
CFM—short for Cubic Feet per Minute—indicates how much air the blower moves. The higher the CFM, the greater the furnace’s airflow capacity.
| Furnace CFM | Compatible AC Capacity |
| 1,200 CFM | 1.5 – 3 tons |
| 1,600 CFM | 3.5 – 4 tons |
| 2,000 CFM | 4 – 5 tons |
For example, a 4-ton AC requires about 1,600 CFM (400 CFM × 4 tons). Choosing a furnace with the right airflow ensures balanced comfort across heating and cooling seasons.
3. Type of Electric Heating System
Electric heating systems in Canada come in several forms:
- Forced-Air Systems: Use ducts to distribute warm air throughout the home.
- Hydronic (Hot Water) Systems: Rely on water heated by an electric boiler that circulates through radiators or underfloor piping.
- Room Heaters: Compact, standalone units ideal for small spaces.
- Radiant Heating: Provides gentle warmth from floors, walls, or ceilings—excellent for allergy-sensitive households.
- Combination Systems with Plenum Heaters: Add electric heating to an existing furnace system for hybrid operation.
4. Installation Location
Installation costs are influenced by where the furnace and ductwork are placed. Attics and basements are typically easier and cheaper to access than finished living spaces. When ducts must be installed behind drywall or ceilings, expect higher labour and material costs.
