What size radiator do I need for my room?

If you are unsure call us on 01422 231943 or email info@radiwarm.com

The RaidWarm comes in many different sizes to fit your room.  What size Pipeless Radiator you need depends on many variables, including wall construction and what type of insulation you have.  Sometimes though, how much wall space you have and the availability of sockets also factor into what size radiator you can install.

The guide below shows the recommended radiator size to heat a room, based on an average UK home with double-glazing.  However, you can buy larger or smaller radiators to fit the space you have – if you buy smaller the space will take longer to heat up.
