Programable TRV's

cubix

Anyone installed these and if so how did they find them. Came across ones from I-temp terrier. I dont have trv's on my rads but plan to do it this spring and wondered would they be worth while.

for them to work u need to keep your heating on 24/7. they are a bit of a gimmick i think

Thanks Sparkpea, I thought these were like normal TRV's but with the option of having room rads turning off at a set time(ie bedroom)

Sparkpea

well yes depending on what time ur clock is set to come on etc. anyone I've spoke to thinks its good for like a home office, coming on at 9am or whatever and the rest not but for that to work you're boiler would need to be able to fire from 9am->whatever time ur lounge or bedroom rads turn off at night. Still the same as regular trvs but its nothing fancy like they can't turn on the boiler to fire the heat or anything thats why its just a gimmick to me.

Why not just have regular valves turned down in rooms you dont use and the room you want to be set higher for when the heating fires

This isn't true. The timer works as long it is suplied with electricity. And the electric valve works along that. The thermostatic element works always. Heating/boiler on or not, battery empty or not. Therfore the term "thermostatic valve".

Buy one Sparkpea. They work even when not installed in a heating system, dry on the table. No gimmik (smiley).

Cubix is correct, they work like normal thermostatic valves. But have a few aditional features build in like timer, frost protection, child lock, window-open function etc...

There are new valves that also send a signal back to a reciever for the boiler to fire.

Sparkpea

are they not powered by batteries then? do you need a new timer and wiring installed then?

can u not just do 1 without doing the rest then?

I've seen new devices that sit on any TRV valve body ,they come with adapters that take the place of standard trv head.

They open and close as a standard TRV ,but the timer on the valve will send a call to the boiler via wireless reciever ,when the temp is needed.
