How can we have all TRVs without Big Brother room stat?

[angst]

We have a Baxi 24 HE Solo boiler fitted on a energy conservation grant.

Crazy government told the installers that we must waste energy though using a room stat in the coldest place - the hall - and to remove the hall radiator TRV. We don't want the hall warmed up, or the hottest place as we're normal people, not like government and boiler makers who spend all their time in the hall.

Previously we had a 30 year old Potterton boiler and all TRVs that gave no trouble.

Any advice from a normal person or plumber who can understand that we want control ourselves over each radiator rather than crazy Big Brother energy wasting energy conservationists would be grateful.

You are wrong to say the government decided it had to go in the hall

Have you got some weird prejudice against governments that causes you to make these untrue statements?

The purpose of the room stat is to automatically turn on the heating when the house is cold (subject to the programmer timing) and to automatically turn the heating off when the house is warm.

As to the placing of the room stat, it ought to go in that part of the house which is slowest to warm up - otherwise it would tend to turn off the heating when the rest of the house was still cold. This is not necessarily the hall, but it needs to be in a room where the radiator will be turned on - otherwise the heating would run continuously. If you like to turn off the radiator in your hall, so that it never warms up, then this position will not suit you.

The room stat should also be in a room that does not have other sources of heat, such as a working fireplace, a cooker, or unusually big sunny windows, as these will make it think that the house is already warm

I gather from what you say that in the past, you had all TRVs and no room stat. This is not an efficient way to run a heating system as it will not automatically turn off the boiler when the house reaches a predetermined temperature.

Your tirade against energy wasting energy conservationists is not sensible.

Which do you want to achieve? Automated energy efficiency, or manual control?

I’m not a heating systems engineer but do understand how they work so guess that means I could fit into the category of “a normal person” . You clearly have no idea about modern heating systems or how to efficiently control them & JohnD’s explanation should make it easier for you to sensibly understand the reasoning behind the need for a room stat.

What’s not been explained is that if you have all TRV’s & no stat, your boiler will continually cycle on it’s own stat as there is no by-pass loop; this is not only very inefficient but can seriously shorten the life of a modern boiler. It has nothing to do with the "greenies" taking control of the country; I think !

Regulations require you to have a boiler interlock. This doesn't have to be provided by a room thermostat - a boiler energy management system can be used instead, and usually would be on commercial size installations. You may find difficulty finding one appropriate for a domestic install.

Danfoss used to do a BEM 5000 but that appears to be no longer available.

If the hall is too hot then turn the hall radiator down a bit, wait until the rest of the house is comfy then turn the wall stat down till it clicks off, and sellotape it.

Crazy goverment give u a grant for a boiler is that not good enough.
Most people have to buy there own!

Joke posting, nobody spotted it, Baxi Solo gives you a clue, ok you can have TRV's on "all" the radiators and do away with the room stat, feed the pump from the boiler "pump" live connection and all will be well in the cosmos, the Solo HE has a built in flow switch, taa daa, and it complies with Part L
