Hall thermostat switches off boiler before other room radiators get warm

Tillysmum

We have new build home where the hall thermostat is very close to the hall radiator therefore the hall reaches the thermostat temp. and the boiler closes down before the other rooms can get warm (these rooms have TRVs). The builders solution has been to turn up the hall thermostat temperature and switch off the radiator in the hall (which has no TRV). I understand that this fooling the heating system into thinking that the hall is not warm enough so the boiler remains on longer, but I can't work out if this is the correct fix as in my mind the boiler will constantly be on trying to heat a space which effectively will not reach the temperature setting as the heat source has been switched off. Given today's energy efficient homes and other initiatives, this surely can't be a sensible solution?

I don't think you want the hall radiator off. Just it needs the flow reduced so that the thermostat isn't triggered by what sounds like an over large radiator for the space.

It's a balancing act. Just experiment with the thermostat, hall rad and room rads to get the desired effect.

Mr.Everready

Move the thermostat to somewhere else ?

Thank you - it can see why you would think this but it is very small radiator for a quite large square hall.

Suggest you close the valve on the hall radiator to off, and then open it up 1/4 of a turn and see how that goes.

With the hall radiator off you rely on heat from other radiators slowly increasing the hall temperature until tge thermostat is "satisfied" and goes off. The risk here is that if the TRVs in those other radiators shut them off before this happens, the boilers stays on heating nothing and will never go off (bar overheating??). As others have said, hall radiator with a low flow will slow things down and allow other rooms to get up to temperature before the thermostat triggers.

Was this builder who fiddled with your heating wearing a Stetson? :cool:

How much did you pay for this new build?

Demand the developer gets the heating enginerr round asap and correctly balances your system. It sounds like it wasn't correctly balanced from the outset, and even if it was the [STRIKE]cowboy[/STRIKE] builder has now ruined it.
Any heating engineer worth their salt would have correctly balanced the system as part of it's commissioning.
(I can't say if the heating engineer employed by the developer is worth his salt, or whether he simply forgot/ran out of time to complete the commissioning)

There is a radiator in the hall as it was deemed necessary by the heating engineer as part of the entire heating system to keep the house warm. The builder seems to think he knows better by simply turning it off. i.e. he tinks it's surplus to requirements, yet you have paid your hard earned cash for it!

Once the system is correctly balanced, see how you get on. If you are still finding the rooms are not warming up enough, ensure all the TRVs are wide open (only turn them down if you feel that particular room is getting too warm)

If you are still not warm enough in the other rooms, then turn the thermostat up until you are maintained at a temperature you are happy with. Ignore whatever number/temperature the thermostat says; it's only there as a guide.

If, after all this, you find a suitable setting, but then find the hall is getting too warm, get the developer to get the heating engineer back and re-balance the system; this time properly!

Then, enjoy your new build home

I would have a look at who your build is governed by possibly National House Building Council NHBC and get them to move the thermostat to a usable position. Its a flaw
