I have removed a radiator and wish to replace using existing pipework and valves. The old radiator itself was 1290mm in width with a total width tail to tail of 1330mm. The pipe to pipe measurement is 1350mm. The height of the old radiator was 430mm however I could go to 500mm with the new one. Guess I’ll need a 1200mm radiator however would be grateful for any advice regarding tails and adaptors (if required) measurements. Many thanks in anticipation.
