Room thermostat, what’s the point?

[Uncle Nick]

Hi all, as it’s starting to get chilly at night, we’re thinking of having the heating on at night… well the wife is.
Which led me to wonder whats the point of having a room stat when the radiators all have their own thermostat controls?
We currently have just a time controller for the heating, is there really any point in adding a room stat?

Yes as the boiler could be heating away and all the trvs shut so wasting gas etc

That’s why you need to remove the trv where the room stat is etc

Thanks for the reply.
The room stat is in the kitchen which has no radiators.
But I get what you mean.

Is it fixed on the wall or movable eg wireless?

It’s fixed to the wall above the time controller.

Yes I thought that but it was there when we bought the house over ten years ago.
The temperature in the kitchen must fluctuate more than other rooms as well due to cooking.

The present arrangement is not satisfactory. It doesn't comply with building regulations, the house temperature will be uncontrolled and uncomfortable and it'll be wasting a lot of gas.

From the description, it should be straightforward to replace the thermostat in the kitchen with the receiver for a wireless programmer/thermostat. Locate the thermostat sender somewhere conventional, e.g. the hallway or a living/sitting room, where it will be influenced by a radiator that has had the TRV removed.

I'd think this simple change will give you a noticeable reduction in your gas consumption, my guess would be about 10%, possibly more. And the house will be much nicer to live in when it the cold weather comes.

Thanks for the detailed reply.
That would make a lot more sense, although the house has always been comfortable in winter and not used stupid amounts of fuel.
A saving on costs would be a great bonus though.
