I was having problems with rads staying hot when CH turned off. I have changed the three port motorised valve and (sorry for the non technical bit) the pipe coming from the bit marked B stayed cold whereas the A and AB were both hot. I assume the B is the hot water.
I thought my problems were over, however now if I switch the CH on the timer to on the boiler (Halsted) it fires up ,but as soon as I switch the HW to the same the boiler goes off. I cannot do the reverse as the boiler never fire up if I put the HW on, but I have hot water?
Hope this makes sense!!!
