In terms of how much space can be heated, electric fireplaces are different compared to other types of fireplace such as wood burning fireplaces or stoves because the amount of heat being produced is set at a permanent and constant value.

With wood burning fires the amount of firewood on the fire and its type and condition can significantly affect how much heat is being produced.

With electric fireplaces, as long as there’s an electrical supply, you’ll always get the same amount of heat being produced.

This is because there are typically no variables when it comes to an electric fireplace heater. The heater is either switched on or off.

The only exception is with some electric fireplaces that have high and low heat settings. Our electric fireplace stove has the option of high and low heat settings.

There are two heater switches on our fireplace, one that activates the low heat setting (generating 925W of heat), and one that activates the high heat setting (1850W of heat).

The low heat setting needs to be switched on before the high heat setting switch will work.

With the high heat setting switched on our particular model of electric fireplace is said to be able to heat rooms up to 570sqft (53m2).

We undertook a test to see how much our particular model of electric fireplace could warm a room by (which is around 160sqft in size). We were able to raise the temperature within our living room by 13.5 degrees F (7.5 degrees C) within 4 hours using our 1850W fireplace that has a fan heater.
