Make sure you install the correct radiator with this easy to use package. The software calculates the radiator heating capacity required  and then  generates a report showing the heat loss details. 

Very easy to use:

 
Enter the room details on screen to identify the room use and shape.

Then enter wall, window and door dimensions.

Handy drop down lists make light work of adding the thermal properties of the various building elements. You can also enter your own values.

 The information you have entered is then used to calculate the individual element heat losses.
A contingency is applied and the appropriate radiator size displayed.
