Hi.
My DIY book tells me that there should be about a 10 degree difference between the flow and the return pipes on a rad.
I have a rad that has no hand valve covers on top so I dont really know which is the lockshield and which is the regulator. My rad thermometers tell me that the difference is just over 20 degrees, the only thing is my instict tells me that the flow pipe is the cooler at the moment.
Anyway, is there an easy way of finding out which is the flow and which is the return?
Brian.
