What size radiator do I need?

What size RadiWarm 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 are a bigger factor!

The below guides show the recommended radiator size 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.

There are also other sized radiators available to those listed here (see product pages). If you’re unsure, call us on 01422 231943 or contact us.
