New Central Heating System Too Hot in Hall / Too Cold in Lounge

[Rialto]

We've recently had a new central heating system installed with a combi boiler and a wireless thermostat in the hall. All the radiators (except the one in the hall which is permanently on) have TRVs. The problem is the hall radiator is far too hot and it's not possible to turn it down manually. The radiator in the lounge seems to have a mind of its own, it comes on at first but then soon switches off when the room is still cold. It has now started to come on occasionally when the room is warm due to the gas fire being on. Most of the time though the lounge rad is stone cold and we leave it on its highest setting of 5. I've tried turning it off and turning it up to 5 - it comes on for a while but then soon turns itself off.

In short, the hall rad is far too hot and the lounge rad is far too cold! Despite being a fairly large rad, we need to have the gas fire on in the lounge. Is it possible the TRV on the lounge rad is faulty (if so, is there anyway of testing it?) or are there any other likely reasons for this and also, is there anyway possible of turning down the hall rad. I understand that this rad has to be on all the time but it is ridiculously hot for such a small hall. We don't use the front door at the end of the hallway so the hall stays uncomfortably hot all the time. Ideally, the hall rad needs to be on at about 10% of its current temperature.

Greatly appreciate any advice.

Thanks in advance

Unscrew the TRV and press the pin down a few times it might of siezed

It will be possible to turn the hall rad down with a small spanner. That may help with the lounge rad as it will force more water towards other rads. As said above, unscrew the thermostatic head from the body of the lounge TRV and check that the pin depresses and springs back easily.

If the rad in the hall is controled by the thermostat it needs adjusting so it is at about 18 degree's.
Then hopefully the rads with trv's will warm up better. Good luck
