hi, i have recently pulled down walls, built a new sunroom and have problems with one radiator that nobody seems to be able to fix. I have upgraded my boiler to a Worcester Bosch 30KW, this is a regular gravity fed system. I have put underfloor heating into the sun room.
I have an 1800mm radiator that just does not get hot, the flow is boiling so is the return, i have balanced the system. bled it. If i mess around with bleeding i can get 3 panels of the 5 panel rad warm, as soon as heating goes off and back on it is stone cold. I have also had a replacement rad and it does he same. Nobody can fix this, can anyone help? A new Groudfos pump was also installed.
when electrician installed electrics for this he said my heating was wired wrong and he fixed it. Been in house from new 23 years and no issues previous. I have BG hive and Speedfit underfloor heating.
Thanks in advance
