Thermostat poorly placed??

[Coops123]

Hi there,

Recently moved into a new build and I am having issues with the thermostat heating.

The thermostat is in the main bedroom which is exposed to the sun all day so the temperature shows as artificially high however the back rooms of the house are cold. I have checked the radiators and they are working correctly with no air locks/ problems with TVR.

Does anyone have any advice on what I can do to rectify this? I have looked at smart thermostats but I am unsure how this would work with the current thermostat installed (I believe its a Honeywell T3). Would moving the thermostat to perhaps the landing or changing to a wireless one work?

Thanks

The room thermostat should be in the coolest room. ie the last to heat up, so that the other rooms have reached their temperature first before the room thermostat turns off the entire system.

A good place to achieve this will be the hall.

You can easily swap your old thermostat with a wireless one, I prefer drayton wiser.

What type of system is it?

Probably best either wireless, move existing if possible, or draw the curtains?

Do you have another downstairs?

I'm assuming that your existing thermostat is hardwired so a hassle to move. But if you get a portable bluetooth connected thermostat and hardwired base station, you can replace your existing thermostat in place with the base station.
The temperature sensing thermostat unit communicates with the base station via bluetooth so you can put it anywhere you want in your house - and can experiment with different locations.

Yes, the thermostat is hardwired. I believe it is the Honeywell T3 range (looks like the one on their website). The house is less than 3 years old.

I have the same thermostat downstairs in the hallway and the heating downstairs feels even throughout the ground floor.

Can you give me an example of a Bluetooth thermostat and hardwired base station? I just keep finding smart thermostats and cannot find any base stations.

I know very little about central heating and have been looking at systems such as Nest and Hive but I'm not sure if they would fix this issue.

Thanks

If it’s a stud wall the answer may be to put it on the other side of the wall

You have a few ways forward - it depends on what you wish to achieve.

As above, moving the stat to the other side of the wall may be the most straightforward.

The Honeywell T3 can be battery, or mains powered; posting a picture of the wiring behind it, may help.us to provide further options.

Just to note, the wiring would still have to be moved to the next room with that one.

The other side is a cupboard with a single radiator in it.

I have attached a photo below. My thermostat also has batteries in it too (2 x AA).

Thanks for your help so far!

Your Honeywell is a two wire stat.
A new smart thermostat could cost a fair amount of money, finding a way to re-route the existing cable may be cheaper; but here are some options...

If you don't mind something mounted on the wall; a Nest Thermostat E Heatlink is battery powered and could be put in its place.
The Nest thermostat itself, is USB powered and could be sited in a more suitable location.

Alternatively, you could have any number of (single channel) wireless smart stats. I.e. Hive, Drayton Wiser, Tado etc.
The receiver could be mounted at the dual zone wiring centre - the cable to the Honeywell could be decommissioned and you wouldn't have an ugly receiver mounted on the wall.

Another option would be to use the hidden grey wire (in the triple and earth cable) behind the Honeywell. It could be connected to a neutral terminal in the wiring centre - enabling power to the receiver, when mounted in place of the T3.

Many of these smart stats also have the ability to link with smart TRVs - something that may be worth investigating if the rooms temperatures are vastly different.

A small cupboard with a radiator in it ?

Then maybe extend the cable and use the cupboard/ surface trunking to get the thermostat into a more appropriate position

Thanks for the info.

I am unable to re-route the cable as the other side of the wall is a small cupboard and the adjacent wall where the thermostat is in the hallway however this is where both doorways meet and space between the frames is non-existent (hope that makes sense).

I understand it will be costly but as its my kids bedroom that's cold, I want to rectify it with the best solution. I also only moved in less than 2 years ago and definitely in no rush to move again!

I believe I have found the zone wiring centre (white box with danfoss logo next to some honeywell valves) this is in a cupboard in another room. So would the receiver be mounted and connected next to the wiring centre?

I have read that they are discontinuing Nest Thermostats, would something like this be suitable?

Would there need to be any amendments to the boiler when changing over the thermostats?

Thanks again

I think its like an airing cupboard, strange I know.

Could the cable be extended and as you mentioned using trunking around the inside of the cupboard to the opposite wall where the back room is located? Would that be safe?
