400mm x 400mm Radiators

Good things come in small packages, and that is especially true with our range of 400mm x 400mm radiators. These pint-sized powerhouses are ideal for small spaces or can work together in groups to keep even large spaces toasty and warm.

Where Would I Need a 400mm x 400mm Radiator?

Small home offices and en-suite bathrooms are the perfect partners for this small sized radiator. Taking up very little space, a single 400mm x 400mm radiator will leave plenty of room for everything else that needs to fit into your small space while maintaining a comfortable temperature.

This size can also provide the perfect solution to attics where the pitch of the roof means a taller option just won't fit. Install a handful of them to keep bigger rooms nice and warm.
