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.

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.

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.
