A guide to heat output

Choosing the right radiator size might feel overwhelming, but our BTU calculator makes it a breeze. Simply enter your room’s dimensions and tell us about your insulation.

The calculator will give you the recommended BTU (British Thermal Units) rating for efficiently heating in your space.

You might need to choose two or more radiators to provide your total BTU requirements. For larger spaces, you might want to look at models with double or triple panels which have a higher output or consider installing multiple radiators - This ensures your room stays warm and cosy, no matter the season.
