I'm about to replace an existing radiator with one the same size. I have measured my existing one as 1346mm x 530mm. These are the physical dimensions of the actual radiator, with no valves etc included. When searching for a replacement radiator I can't seem to find matching sizes. I can only find 1400mm x 500mm or 1200mm x 500mm. Obviously I'm not too bothered about the height and I appreciate that it won't be exact, but I thought the length might be closer e.g. 1300mm. Am I measuring the wrong length - should it includes valves?
Thanks for any replies,
Rebecca.
