I'm wanting to change my old radiators but am having problems with the sizes. I have 3 that measure 620mm x 1600mm which is fine but I then have one that measures 620mm x 640mm and 2@ 620mm x 960mm. I've looked on loads of websites but can't find these sizes anywhere. Do they exist anymore? If not should I go for the nearest size up or down but will I need to alter the pipes that are already in?
The odd sizes are because they are imperial radiators & not metric. Go for the nearest size down and get radiator valve extenders. These are telescopic radiator valve tails which slide out to take up the short fall. Any good plumbers merchans should have both the radiators & extenders.
