kW (kilowatts) output calculator

Follow the three easy steps to find the perfect stove or fireplace for your home: 

1. Enter your room's measurements. 
2. Select the level of insulation.
3. Browse from the recommended products.

Insulation type explained

• Poor: homes typically built before 1950, or if you have draughts and little to no insulation
• Moderate: homes typically built in the 1990s and fitted with double glazing
• Well insulated: homes typically built after 2008 are airtight as this is when compulsory heating standards were introduced

Output calculation explained for what kilowatt stove do I need?

We use the standard calculation used in the UK across the industry to work out the kilowatt output needed. The calculation multiplies the height, width, and length of the room you're looking to heat, and divided by a number between 10-25 depending on the level of insulation or year your home was built. 

Other considerations for the 

• Factors such as the size of your windows and any other areas or stairs attached to the room which isn't fully enclosed will affect your choice. 
• All of the stoves and fireplaces sold by Glowing Flames are measured in kilowatts (kW). The higher the output, the greater the heat generated. 
• You will also see the terms 'nominal heat output' and 'maximum heat output' - nominal is the output where it is efficiently producing the output, and maximum is referring to the highest limit a stove should achieve.
