Really stupid question, I know....but I have no thermostatic valves on any rads in our house (7 rads in total). The system needs balancing but I don't know which are the thermo valves and which are the lockshield valves. How can I tell??
Ok thanks for that but all the rads had wheelheads at both ends when we moved in!! I think I've sussed ot out now though, I'm guessing the flow pipe will heat up before the return pipe when the heating is first switched on???
Also, is it possible that the boiler pump needs adjusting so that it has enough power to supply the 3 extra rads that we had installed to the system? If so, is that something I can do myself?
