Buyer’s Guide

Before purchasing a space heater, look at what type of fuel the model uses, how large of an area it can heat, how efficient it is, and what safety features it has. Here’s a breakdown of these factors.

Fuel Source

Space heaters are powered by gas, oil, or electricity. Gas and oil heaters require a certain type of fossil fuel to run, but you don’t have to worry about plugging them in. Electric heaters are safer to use, but they have to be placed near an outlet. They may also increase your monthly electricity bill.


Each space heater has a maximum number of square feet it’s capable of heating. Measure the area you plan to heat, and buy a heater with a capacity to match that space.


Heaters with fans or a forced-air construction are quicker at emitting heat and better at evenly distributing it. On the other hand, gas and oil models take longer to heat up.

Safety Features

Some space heaters automatically switch off after reaching a certain temperature to prevent overheating. Others have sensors that detect if the unit has tipped over to prevent fires.

Frequently Asked Questions

Can I use a space heater as my only source of heat?

Space heaters likely won’t produce enough heat to warm your entire home, so we recommend turning on your heating system and only using your space heater in smaller areas.

Can you leave a space heater on overnight?

No. We don’t recommend leaving your space heater on if you’re asleep or out of the house because it could start a fire, cause carbon monoxide poisoning, or dry out your skin.

How much electricity do space heaters use?

The average electric space heater uses 1,500 watts per hour. Depending on how much your utility company charges for electricity and how long you use your heater for, a space heater will cost you about $2 to $4 per day to run.
