Radiator heat output


Heat Loss Calculator

If you’re not sure which radiators you need, you can use two methods to calculate the appropriate heat output required to keep a room at a comfortable temperature. 

Choosing the right radiator can help reduce energy bills.

By performing a Heat Loss Calculation, you can calculate Watts required for a particular room. 

This ensures that your rooms will be heated comfortably and efficiently.

Please note: Heat Loss Calculations are only estimated and are based on information you provide. 

Any results provided should not be considered 100% accurate and we accept no liability for any errors resulting from the estimates given.

Method I:

The size of a room and the desired temperature in a room determins the heat requirement for the room. The calculation is as follows:

Calculate the content of the room length x width x height.

For example : 8 meter long, 5 meter wide en 2.60 height 8 x 5 x 2,4 = 96 m3

Determine the desired temperature in the room.

For example: This living room is the needs 153 BTU per m3. The total capacity for this room is: 96 m3 x 153 BTU = 14688 BTU


Method II:

Do you want to replace an existing radiator, according to the type and dimensions of this radiator you can find the capacity in the table below, these BTU values ​​are listed according to EN442 75/65/20.

First, determine the type of radiator.




Then locate the BTU output of the radiator on the basis of the dimensions:
