Thermostatic Radiator Valves, Advice needed

metricspaces

I have an A3 rated new build house that has gas heating, with radiators. There are two zones, one for upstairs and one for downstairs. I am wondering if it is a good idea to fit TRVs to the radiators?

There are a few rooms in the house that will be rarely used and one or two rooms that will never be used. My plan was to put the TRVs in these rooms and set them to the lowest possible setting.

The temperature in the other rooms would then be regulated by the central control via the two zone settings.

If it is a good idea to fit TRVs, then I am torn between fitting only the few rooms with TRVs or fitting them to all rooms.

It is not costing me anything to fit the TRVs. I can get PEGLER TERRIER TRVs for 12.50. If I fit the few rooms it costs me 62e, if I fit all rooms it costs 137e. So I am thinking, for the extra cost of 75e I may be better fitting all rads with TRVs?

How is it costing nothing?

There's no cost to me for fitting.

Is it a good idea to fit TRVs to the radiators based on scenario outlined in previous post?

If it is a good idea, should I fit to all radiators or just the few I mentioned above?

If it's free then fit to all as little my as you've no solid fuel heating the rads.
I wouldn't use pegler. A great name but I always get trouble with their trvs. They always stick and become very stiff.

Thanks! What TRV would you recommend?

I assume there's no problem fitting TRV to same room as room thermostat as long as you leave TRV on hottest temperature setting (so no conflict between room thermostat and TRV). It's just a waste of a TRV?

Fully agree I thought it was only me that had issue. I've 30 plus pegler terrier valves and I reckon 5 or 6 keep sticking. Avoid

Ye it'd be a waste of a trv. Myson petite are a nice valve

Get PRV heads. They have built-in anti scaling timers.
They also give great individual control over time and temperature for each room.

Excuse my ignorance, but what are PRV heads? (Google tells me nothing! )

They are P grammable. You can set times and temperatures on each one.

Nice one, thanks!
