Baseboard Heater vs Furnace: Heating Cost, Efficiency and Best Use Cases in Canada

Heating decisions in Canada aren’t just about comfort—they directly affect monthly energy bills, resale value, and long-term living costs. One of the most common comparisons Canadian homeowners and condo residents make is between a baseboard heater vs furnace.

If you live in a condo, apartment, or older townhouse, you’ve likely encountered electric baseboard heaters. If you own a detached or semi-detached home, a gas furnace is probably your primary heating system.

This guide breaks down how baseboard heaters work, how much they cost, how they compare to furnaces, and—most importantly—which option actually makes sense in Canada’s climate.

A baseboard heater is a type of electric resistance heater installed along the base of walls. It heats air by passing electricity through internal heating elements. As the air warms, it rises naturally, pulling cooler air in from below—a process known as convection heating.

Baseboard heaters are commonly found in:

  • Condos & apartments
  • Rental units
  • Older townhomes
  • Small homes without ductwork

Types of Baseboard Heaters in Canada

  • Electric baseboard heaters (most common)
  • Hydronic (liquid-filled) electric baseboards—better heat retention, slightly lower operating cost
  • Low-profile vs standard units (size affects output, not efficiency)

🔍 Important: Almost all baseboard heaters in Canada are 100% electric—meaning they rely entirely on electricity, not gas.


Baseboard heaters are attractive upfront—but expensive to run long-term.

🔧 Installation Cost

ItemTypical Cost (Canada)
Baseboard unit (per room)$150–$400
Electrical wiring (if needed)$300–$800
Thermostat (line-voltage)$50–$150
Total per room$500–$1,200

For a 1,000 sq ft condo, total installation usually ranges from $2,000 to $4,500.

⚡ Monthly Operating Cost (Electric Baseboard Heating)

Electricity is one of the most expensive heating fuels in Canada.

Home TypeMonthly Heating Cost
1-bed condo$120–$200
2-bed condo$180–$300
Small townhouse$250–$400
Detached home$400–$600+

In provinces like Ontario, Alberta, and BC, winter electricity rates can make baseboard heating 2–3× more expensive than gas furnaces.


✅ Pros of Baseboard Heating

  • Low upfront cost
  • No ductwork required
  • Room-by-room temperature control
  • Quiet operation
  • Simple installation

❌ Cons of Baseboard Heating

  • High monthly energy bills
  • Slower heating response
  • Uneven heat distribution
  • No air filtration or humidity control
  • Not ideal for cold Canadian winters
  • Poor resale perception of houses

⚠️ Efficiency Note: While baseboard heaters are technically 100% efficient, electricity itself is far more expensive than natural gas—making furnaces cheaper overall.


💰 10-Year Cost Comparison (1,500 sq ft Home)

Cost CategoryBaseboard HeatingGas Furnace
Installation$3,500$6,500
Annual Energy Cost$3,600$1,600
10-Year Energy Cost$36,000$16,000

10-Year Total$39,500$24,000

📉 Gas furnaces save ~$15,000 over 10 years for a typical Canadian home.


Baseboard heaters do make sense in certain situations.

✅ Good Fit For:

  • Condos where gas is unavailable
  • Apartments with individual room control
  • Small spaces under 800 sq ft
  • Rental properties (short-term ownership)
  • Secondary or seasonal residences
  • Detached or semi-detached homes
  • Families with high winter usage
  • Cold regions (Prairies, Northern Ontario)
  • Homeowners planning long-term ownership

Toronto Condo (900 sq ft)

  • Baseboard heating cost: ~$220/month (winter)
  • Annual heating cost: ~$2,400

Mississauga Detached Home (1,800 sq ft)

  • High-efficiency gas furnace: ~$140/month
  • Annual heating cost: ~$1,600

➡️ Larger home, lower annual heating cost — thanks to a furnace.


If you’re currently using baseboard heaters, switching to a furnace may be worth considering if:

  • You’re converting a condo to a townhouse or house
  • You’re buying a resale home with baseboard heat
  • You plan to live in the home for 10+ years
  • Natural gas access is available

Many Canadian homeowners start with baseboard heating, then upgrade to:

  • Gas furnace
  • Cold-climate heat pump + furnace backup

Furnace TypeInstalled Price
Entry-level furnace$4,500–$5,500
High-efficiency furnace$5,500 – $7,500
Variable-speed premium$7,500–$10,000

Baseboard heaters are simple and affordable upfront—but expensive long-term.
Furnaces cost more initially but deliver lower bills, better comfort, and higher home value.

🏆 Bottom Line

  • Condo or apartment → Baseboard heater may be acceptable
  • House or long-term ownership → Furnace wins every time
