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