Frequently asked questions
About 15¢ an hour at full power, at an example rate of 10¢ per kWh. The math is simple: 1.5 kW × 1 hour = 1.5 kWh, multiplied by the rate on your bill, which depends on your province and utility. A thermostat cuts the real cost, because the heater switches off once the room is warm. Three hours a day at full power for a month comes to 135 kWh, about $13.50 at that rate, so heaters suit short, targeted use rather than all-day heating.
Only for short spells in one room, because a kWh of electricity usually costs more, often several times more, than the same heat from natural gas. Warming a home office for two hours with a 1.5 kW heater uses 3 kWh, which can still cost less than running a gas furnace for the whole house. Running heaters in several rooms all evening is almost always more expensive. Compare the electricity and natural gas rates on your bills before deciding.
Neither: at the same wattage both turn every kWh of electricity into the same amount of heat. The difference is comfort. A ceramic heater uses a fan to warm a small room fast and suits short bursts, like a bathroom before a shower, but it is noisier. An oil-filled heater warms up more slowly, stays warm after its thermostat clicks off and is silent, which suits bedrooms. Savings come from a good thermostat and timer, not from the heater type.
It's best not to: plug it straight into a wall outlet. A 1,500 W heater draws about 12.5 A at 120 V, close to the limit of a standard 15 A household circuit and more than many extension cords and power bars are rated for. Never use an extension cord reel without fully unwinding it, and never share the outlet or circuit with other high-power appliances. Keep the heater 1 m (3 ft) from curtains and furniture, don't dry clothes on it and choose one with tip-over and overheat protection.
Usually its overheat protection is kicking in because air can't flow freely around it, or the thermostat has simply reached the set temperature. Move it away from walls, curtains and furniture, and dust the grilles. On a soft carpet the tip-over switch may think it has fallen. If a breaker in your electrical panel or a GFCI outlet trips when it switches on, stop using it and have the heater and circuit checked by a licensed electrician.
