Buying Guide


How to pick the best energy efficient space heater

When picking a space heater, you need to consider the size of your room. If you have a large room, then you need to opt for a more robust space heater. Measure how large your room is in square feet. Then, you’ll be able to work out how many W your space heater will need.

While we’ve included more specific calculations below, the general rule is every 10W = 1 sq. ft. covered efficiently.

Measure how many sq. ft. your room has, then multiply it by 10 and that’s how many watts you need.

What makes a space heater energy efficient?

There are two main aspects that make space heaters energy efficient. First, the majority of space heaters, and all of those included on our list, contain multiple wattage settings. This will allow you to select a lower wattage and warm your house up slower, while saving energy.

Additionally, due to the range of thermostats and heat regulators that come with space heaters, you can choose a temperature and then maintain it. Instead of blasting out heat, your space heater will carefully maintain the room’s temperature.

Over time, this will save energy and ensure you can cut back on your utility costs.

How should you prepare your room for a space heater?

You’d be surprised to know that, while space heaters are incredibly safe, their misuse can lead to dangerous situations. One way around this is to buy space heaters with safety features. All the heaters on our list are made to resist overheating and will deactivate if their internal core temperature reaches a dangerous level.

However, there are also some general rules to follow if you want to place your heater in the perfect location. First, make sure to place the space heater directly on the floor. This means you don’t want to put it on a rug, on your bed, or on a towel. Put the heater on a smooth, flat floor space and leave it there.

You should also keep your space heater away from water. Don’t place the heater next to your sink or the bathtub, for example. Wet locations could lead to an electrical short circuit, which may damage your space heater and lead to a fire.

Additionally, you’ll want to avoid putting flammable objects within 3-feet of the space heater. Things like curtains, newspapers, cushions, and bedding are all flammable and can catch fire if they become too hot. Try to keep anything that’s flammable as far away from the space heater as possible.

Finally, do not leave the room when the space heater is on. If something were to happen, those initial moments are the difference between managing the situation and having to deal with a severely escalated problem.

How many watts does a space heater need to have for sq. ft. sizes?

The general rule when it comes to space heaters is that every 10 watts of heating power will cover one square foot of your room. Of course, every room is different, and this number will not be 100% accurate.

In general:

  • 750 W – 75 sq. ft.
  • 1000 W – 100 sq. ft.
  • 1500 W – 150 sq. ft.

These measurements are a little on the lower side. While a space heater of 1500 W will quickly heat a room of 150 sq. ft., it can also manage spaces up to 200 sq. ft.
