Thermostats in each room?

[SSE]

Anytime I've done a boiler/heating system for someone it;s just been ur usual one thermostat for the system. Now someone who wants a new system would like one in each room? Can someone explain to me how this would work or if it does as I'ver not heard off this before and think it's a bit over the top.

I thought that what thermostatic valves were on the rads .........but I could be wrong.

Just tell them thats what thermostatic valves are for!

sounds like multizone,cant see that being a combi,would need seperate motorised valves for each heating circuit,and seperate stats for each zone.what type of system is being installed,by the way i think this might need to relocated to the central heating threads.

Any time i have done this it has been for an underfloor heating system. Each room is plumbed in its own loop. So therefore there is a stat to control each loop. It is a handy system when you get onto the run of it and gives the homeowner alot more control over the system. I have a system like this in my house if you need a pic a will post one

The TRVs on each radiator do the same job. Thats why we have em

Not much use for underfloor tho

 

[Amp David]

II know that! OP never stated underfloor

 

[Hawk81]

I have never saw thermostats in each room on a ordinary radiator system.

 

[Amp David]

I've never seen em either. Wires crossed?

what I meant was the TRV does the same thing that a thermostat per room would do.

 

[Hawk81]

Yes wires crossed mate. I understand your point now.

I've just done a system with 4 thermostats, they were to control the min temperature of the house eg to make sure no room got colder then 10c. Did advise about other room being heated when just 1 thermostat calls for heat and was told that what the tvr are for.

It's more common with underfloor systems, but just as applicable with radiators. TRVs are an alternative, but have their disadvantages. TRVs are positioned very close to the heat source. TRVs are rarely programmable. You can get room stats that have 7 day programming and are networked to allow control from a central touchpad, PC, telephone, etc. Mind you, TRVs are much cheaper.

There is pretty much only one manufacturer of the networked room stats - heatmiser. Many other companies sell rebadged versions though.

just imagin all the motorised valves around the place , TVR's , and as has been said room stats for each room on a Zoned under floor heating system

I installed a system 25 years ago in my own house with a tank and 8 room thermostats. Therefore 9 motorised valves.
It made one hell of a difference to the gas bill.
