The cheapest type of heater to run in Canada

Every plug-in electric heater is about 100% efficient

Resistance heating turns essentially all the electricity it draws into heat in your room. A ceramic heater, an oil-filled radiator and a coil fan heater set to the same wattage for the same hour cost exactly the same to run.

So when a listing claims a heater 'uses 90% less energy' than other heaters, treat it with suspicion. Savings come from heating less space for less time — which is a real and large saving, just not a magic element.

Heat pumps are the genuine exception

A heat pump moves heat rather than creating it, delivering two to four units of heat per unit of electricity. Where a cold-climate heat pump is practical and affordable to install, it is the cheapest electric heating in Canada by a wide margin.

It is also a several-thousand-dollar installation, which is not the answer to one cold spare room in November.

Comparing the common options

• Cold-climate heat pump: cheapest to run, expensive to install, whole-home solution
• Natural gas furnace: usually cheap per unit of heat where gas is available, heats everything
• Ceramic PTC plug-in heater: same cost per unit as any electric heater, but heats one room fast — cheapest fix for a single cold room
• Oil-filled radiator: identical cost per unit, slower, so often runs longer
• Electric baseboard: identical cost per unit, no thermostat precision in older units, always-on zones
• Coil fan heater: identical cost per unit but typically no thermostat, so it runs flat out and ends up costing more

The practical answer for most households

Keep the central system at a sensible baseline for the whole house, then add a small thermostat-controlled heater in the one or two rooms you actually occupy. That combination beats both extremes — running the furnace hard, or freezing in one room.

Why no electric heater is more efficient than another

Every electric resistance heater — ceramic, coil, oil-filled, infrared, panel — converts essentially 100% of the electricity it draws into heat in your room. There is nowhere for the energy to go except into the air and the objects around it.

So when one brand claims to be more efficient than another, what is being compared is either the control system or nothing at all. The real variables are the wattage drawn and the number of minutes the element spends powered.

Heat pumps are the genuine exception

A heat pump does not create heat, it moves heat from outside to inside, which is why it can deliver two to three units of heat for every unit of electricity. Per unit of heat it is the cheapest electric option in Canada.

The trade-off is installation cost in the thousands and the fact that it heats the whole home rather than one room. For a single cold bedroom, a $59 plug-in heater used for a few hours a day is the cheaper answer; for replacing your heating system, a heat pump wins comfortably.

Ranking the options honestly

• Heat pump — cheapest per unit of heat, highest install cost, whole home
• Natural gas furnace — cheap per unit of heat in most provinces, heats everything
• Thermostat-controlled plug-in heater — cheapest way to warm one room for a few hours
• Oil-filled radiator — same cost per hour, slower to respond, harder to move
• Coil heater with no thermostat — the most expensive way to stay warm, because nothing switches it off
• Baseboard heating — convenient, but heats whichever room it is installed in whether you are in it or not
