25mm each side was what i was thought for valves so if the rad is 4ft that equates to 1200 rad and 50mm for both valves wich means 1250 you also need to come out 15mm for a single panel and 25mm for a double panel if coming from the floor..

Add 80mm for ordinary rad valves, 90mm if using a TRV, consult manf. brohure for distance from wall
