Hello all,
Trying to get the above running efficiently. Boiler fitted to existing system. Installation docs state
flow temp=75
Return temp=65
Everything I read says the dt should be 20?
So if I try to balance the rads what DT am I working to?
I've managed to work out the rad order using digital thermometers & have managed to get them all roughly the same temp (within 3 degrees) but can't get the rad flow & return pipes to differ much.
All advice greatly appreciated
