How much electricity does a space heater consume?

Most residential space heaters on the market today use a maximum of 1,500 watts per hour. However, many manufacturers have also come up with devices that consume as low as 200 watts.

When buying the unit, ensure to check its wattage on either the user manual or the print. That will allow you to know how much electricity it will consume in an hour.

For example, if you buy a unit that has 1,500 watts, it will consume 1.5 kilowatts of electricity. If you run it for 24 hours, it will use 1.5 x 24 = 36 kilowatts per hour.

Multiply the number by the rate your power company charges for electricity (say 10.48 cents) you get $3.77 per hour.

For a detailed breakdown, check out this space heater electricity consumption guide. It also explains ways to minimize electricity costs when using a space heater.

How to save energy costs when using a space heater

If you are planning to buy a space heater, here is how you can lower your monthly heating costs:

  • Heat for a few hours: Reduce the number of hours you are heating your home. Only use the unit when you need it.
  • Air-tight your home: Start by sealing off any spaces that might bring in cold air from the outside. Close your windows and doors during the day to keep warm air inside.
  • Use a low-wattage unit: Rather than buying a device that consumes 1,500 watts, consider going for a smaller one that only takes in 200 watts.

Also, consider a unit that comes with a thermostat. It will help you to set the heat to a temperature that will only keep your room warm without wasting energy by overheating the whole area.

How long should you leave a space heater running?

The duration to leave your space heater on will depend on various factors. These include the size of your room, the temperature of the house, and your comfort level.

In general, leave the unit running for the number of hours you are using it. If it is not in use, consider switching it off.

Also, if you think the temperature of your house is comfortable for you, then you do not need to use the device.

If you tend to forget switching it off, or you need to find your home at the right temperature, consider purchasing the best smart space heaters for large rooms.

Factors to consider when buying a space heater

If you are on the market for an energy-efficient heater for a large room, here are some things to put into consideration.

  • Remote control: The remote control aims to help you operate the unit from a distance. You will use it to turn the heater off or on while on your couch or bed.
  • Thermostat: It is a feature that allows you to set your heater so that it can turn on when the temperature in your room is below a specific limit. The advantage is it can help you to save energy.
  • Heating capacity: Consider buying a space heater based on the area of a room it can cover. In other words, look at its wattage. These devices use at least ten watts to heat a square foot. If you buy a unit with 700 watts, it will only cover 70 square feet.
  • Noise levels: Since it is an electronic device, a space heater will produce noises when in operation. Consider purchasing one that is not noisy by looking at its decibels level.

Other things to consider in the unit include safety features, warranty, and energy-saving capability.


The best space heaters for large rooms are those that can maintain or adjust room temperature automatically without your input.

Also, consider a unit that has safety features and prevents overheating. As a homeowner, go for an appliance that helps to save energy and comes with two or more heat settings.
