Advice for fitting TRVs, room stat needed

[Alan]

With the imminent arrival of winter and the patter of tiny feet, and all the advice that goes with that about keeping the house 'warm' I've decided to either get (or fit myself) some TRVs fitted.

The current setup is a sealed system with 13 rads (one with a TRV already) and a room thermostat in the living room. This has the usual problem of the living room being just right and the rest of the house being cold, so I need to make sure I sort that issue out otherwise to get the nursery at the right temp the living room will be unbearable.

I asked the man from BGas for a quote when he was servicing the boiler, he said don't bother, would be =A350 per rad, a wireless thermostat would be =A3100-150 (!) but I should definitely get the room themorstat moved, probably into the hall, and leave the radiator at the top of the stairs without a TRV.

Does this sound right? How much would it all cost DIY, and what would be a sensible quote to look for if I decided to get someone (other than BGas) in?

Any recommendations for decent TRVs and wireless themostats?

Without knowing how your house is laid out and oriented it is difficult to give precise answers.

In general an inside thermostat should go in a room not affected by internal heat gains and the sun. A north facing bedroom may be ideal.

If the heating can be re-arranged to put the nursery on a separate zone controlled by its own thermostat that would be ideal.

Do you have any other sources of heat in your living room? Have you checked your radiators are correctly sized?

A cheap solution could be: Move your stat to the coldest room and fit TRVs on some radiators in the hottest rooms.

BG is usually very expensive - you could try getting a quote from an independent heating engineer.
