Heating Area

Since we are more concerned with large rooms, the best space heater will warm up a normal-sized room in 15 minutes. Even so, remember that infrared models are usually used for specific zones in the room, only particular models can heat an entire space.

Generally, a space heater uses 10 watts of warming power to heat a single square foot of your room, but this doesn’t apply to all models.


Space heaters, without a doubt, are meant to be hot. Nevertheless, they shouldn’t create a fire hazard or burn you. Find a sensor that switches the heater off if it overheats. Also, taller models are a welcome option if you have kids or pets using the room.

When shopping for the most efficient electric heater for your home, look for a label from a reputable test center such as Intertek, Canadian Standards Association, and Underwriters Laboratory.


A heater with a working thermostat feature can save you money as it will turn the heater off and on as needed and allow you to set the required room temperature. Other special features to look out for include energy saving modes, programmable timers, and low wattage.
