Thermostatic Valves

[Raji]

Hello I am getting a new boiler put into my property. currently the rads do not have thermostatic valves. I take it is good practice to have these installed. Is it an issue on older rads? They all seem fine. Also what is a good quality valve in terms of design and function. I remember having a couple go at a previous place I had and these seemed like cheap tat. Does anyone have a recommended one to go for? Cheers Raji

Hi Raji, it is good practice and also part of the building regulations part 'L' conservation of energy. The TRV's enable areas or rooms to not be heated when not required (bedrooms during the day for example), and also allow better heat control on other rooms, saving energy and hence money.
There are many good and not so good valves, Honeywell, Drayton and Danfoss are all good valves IMHO.

I've had Drayton TRVs on for past 7 years, and no problems with any of them yet.

I like the Pegler valves. The TRV's I see that have issues tend to just have a small pin in the middle, a lot of the good ones have a more substantial stud. Don't know if this has anything to do with it or if it's just a coincidence.

Stay away from the Pegler Gen II valves though, I've had issues with the plastic heads snapping off.

Honeywell valves for me. The more control you have over your system the more efficient it will be. Will probably work out cheaper for you to get the installer to fit them when doing the boiler as it will be drained down.

I've fit 100's of Danfoss and never had a problem with them.... Just dont buy the screwfix/b&q "cheap" trv's as after a while you'll end up with the pins sticking, then you'll go to release the stuff pin and bang, water ****ing out valve. New TRV.

The worst one's I've ever tried to get working were Giacommini
