trv

Fitted my first trv yesterday using a freezer kit and no leaks overnight! I didn't fit the head though as didn't want to damage it as still got wallpaper to strip behind where the rad was. I can't take the temporary cap off because I have to turn it on to release it. Can I wait until the new rad...

Hi All, (Apologies, my plumbing skills/terminology need much improvement) I recently found a leak on the joint of a TRV valve coming from one of my radiators, it seemed to be where the pipe enters the valve (see image and imagine the silver pieces of the valve are bone dry). I had someone...

Hi, please can anyone offer any help. I've just had a number of radiators fitted as part of a large extension. I've gone from 8 to 14. All the radiators in the house bar the bathrooms have therostatic valves. Obviously some brand new and the older ones, well, old. My old heating system was...

I apologise if these sound silly questions, but I would love some advice on making threaded fittings weep-proof. I have 1/2" Danfoss Randall RA-G Single Pipe TRV Body which comes with a fitting which screws onto the 1" OD outlet of the TRV and screws into the radiator. (see...

How do I connect a 15mm pipe to a 1" diameter male "O" ring type fitting? See photo. I am replacing an Imperial radiator in a single pipe system with a metric one which is quite a bit shorter. I have bought a 1/2" Danfoss Randall RA-G Single Pipe TRV Body which comes with a chrome fitting...

My radiator isn't working and after reading the forums here, I thought it was a small pin on the TRV that was causing issues. But after checking the pin, it was clear that it was working fine but the head itself was causing issues. The black spring in the head that moves as the TRV head is...

OK - I know I'm a plonker ... :-) I had to replace the head of a TRV, bought a new one and then threw the old head away before fitting the new one. Sod's law came in to force to ensure that the new head wouldn't fit the TRV and I can't remember the manufacturer. There's what looks like a logo...

Evening all, I have taken the decision to change my bedroom radiator, its only a single type 11 currently and just is not producing enough heat. I think imp going to op for the type 21 not 22 as the larger one will be overkill and stick out from the wall 107mm as its a Barlow from screw-fix...

Your average TRV works by sensing the radiator water temperature (it's bolted to it, after all) and I need something that actually senses the room temperature, to respond to opening the door and whether or not the woodburner is alight. I don't want to go to the bother of Zones. What I think I...

I've been looking into home automation and have my eyes on the Evohome system. This controls your radiators TRV's. Unfortunately none of my radiators have TRV's - they are all fitted with these types of valves: http://www.screwfix.com/p/angled-radiator-valve-drain-off-15mm-x/70408 So first I...

Hi I was hoping for some help and advice. I recently undertook a decorating project in my two bedrooms upstairs. I removed the radiator in each room, closing the TRVs to isolate them both. All was going fine until about a week later (with the radiators still removed) one of the TRVs had started...
