Prorad double panel single convector

Great heat output with a double panel radiator

Double panel convector radiators, otherwise known as Type 21, benefit from a single convector that has been sandwiched between two single panels. The convector is only fitted to one of the panels and they are a bit thicker than a standard, single panel radiator but they do provide a much higher heat output. Due to their size their ideal for heating small to medium sized bedrooms.

Line Break
Prorad fitted grills top and sides

Includes pre-fitted side panels and a top grill

You'll easily be able to conceal the internals of the radiator with the factory fitted top grills and side panels. They provide an elegant finish to the radiator but without hindering any of the heat output that you receive from it.

Line Break
Prorad includes mounting brackets

Easy to install fixing brackets

Also included with the radiators are the heavy-duty L shaped fixing brackets which bolt directly to the wall and course the airvent, blind plugs, screws and screw caps.  The brackets fit directly to your wall and the radiators simply hang on them using the holders pre-fitted to the back of them.

    Bought this Rad to replace an old single panel Rad. Finish’s off a newly decorated hallway nicely and giving off a lot of heat - which is probably overkill seeing as it is the same length as the old one. Only problem I faced was not ensuring the tails were super tight before fitting to the wall - one end started to loosen as I tightened the pipework to it (tightening in the opposite direction) - user error!

    I went for this brand as it had a higher heat output than the Screwfix/Toolstation/B&Q equivalent. It is well made with a good finish. All the normal fittings included. I would buy again.

    While we had work done on our house. I ordered one of these radiators as our old one was scratched and old looking. And for the price it's made a huge improvement on the clean look

    I needed to replace all my radiators as they were over 35 years old. These look better and seem to heat up quicker. Great buy.
