Hi
At my old house I had a CD32 it was a five bed semi, all rads had thermo valves and the system was balanced well as in all heated up together and then the thermo valves shut off accordingly with the main hall radiator having valves (non thermo) open both ends. This was of course where the thermostat was.
New house is a bigger four bed detached and plumber suggested CD37 or 42 but we ended up going for the bigger one due to hot water demand (2 bathrooms and cloakroom) and possible loft conversion later.
Anyway, the whole system needed re-doing as it was run in 15 all the way (purchased the house off a plumber who had lived there for year and done the central heating himslef!). Downstairs was finished first and new boiler fitted. Every time I change a radiator to a new one (the old ones are the non fin type, they're that old) I fitted a thermo valve.
But got the upstairs going and the rads don't seem to get very hot until the thermo's downstairs start shutting off. The only difference with the old place is boiler was upstairs; in the new place it’s downstairs in the cloakroom.
Should I be adjusting the non thermo valve end on each rad downstairs to push the circulating water upstairs? I thought with a pressurised system there was less need to do this?
Any thoughts?
Thanks
