How Much Energy Does A Space Heater Use

Click calculate to find the energy consumption of a space heater using 1500 watts for 5 hours a day 0 12 per kwh.

How much energy does a space heater use. Your electric heater wattage tells how much electricity is needed to power it. The first step in finding out how much energy your electric space heater uses and what that might cost is to find the wattage. Department of energy points out that operating one is even more expensive than a combustion space heater that runs on kerosene or another kind of fuel.

An electric space heater uses approximately 100 watts on an average an electric space heater is used around 5 hours a day. 1 000 watts equals 1 kilowatt. Space heaters usually range from 750 to 1 500 watts.

This should be printed on the heater itself or in the owner s manual. Actual energy consumption and cost may vary. Secondly your space heater use in hours per day will impact how much energy it uses.

Apply this formula to calculate how much your space heater energy cost to run a 1500 watt heater for 24 hours. Click calculate to find the energy consumption of a space heater using 1500 watts for 5 hours a day 0 10 per kwh. The maximum power rating of the heating element on an oil heater is the same as it is for conventional electric space heaters 1 500 watts.

So if you have a 500w unit that s 1 2 or 0 5 of a kilowatt. Most electric space heaters run at 1 500 watts so we will use that number in our examples for calculating electricity use. In addition most models have a low energy setting of 700 or 800 watts and there may be a third setting between these two.

Space heaters are typically not an efficient means of heating especially compared to a central heat pump geothermal heating or solar energy. That means that your electric heater consumes about 1 5 kilowatts of power. 1 500 x 24 hours 36 000.
