Thermostatic Radiator valves.

[Henryv]

Warm greetings.
I am a new member.
Please can you tell me which are the best Thermostatic Radiator Valves
money can buy. I am having some new ones fitted to replace ones that are always sticking.
Could you also say which Bi-directional Thermostatic Radiator valves are
best quality.
Are there any disadvantages in fitting Bi-directional?

Henry.

I fit trv4s but there dear

 

[Henryv]

Are they Bi-directional JB?

The Drayton brand, about £25 I think but offers vary

AFAIK all modern TRVs are bi-directional now.

I have a gold-plated one in the bathroom to match the taps

Danfoss also make a good TRV, their ones with the plastic top are cheaper but the chromed one is abouthe same price as the Drayton.

 

[Henryv]

Thank you very much.
The Drayton TRV 4's look just the job!!

Honeywell VT200's are also pretty.

None of them last very long though. I don't find TRV4's particularly good. The pin is in plastic and very thin, so sticks easily. Recently fitted some Mysons which were far more robust, with a completely brass valve.

Thanks Chris,
Which Myson was it? TRV11?
Are they ok for a single pipe system?
Approx' how much are they?

Peglar Terrier every time. Splendid valves. Never had a problem and last very well too.

 

[Henryv]

Would you replace the valves at both ends or leave well enough alone?
They are probably over 30 years old.

Henry.

 

[JohnD]

change both, of course.

Use lockshields with drainoffs if they are on downward loops or you are short of drain points (especially next to external doors so you can poke a hose out)

Best give it a good clean while you're at it. If you take the old rads into the garden you can squirt them through with a hose. Use x400 for a week or two first to loosen old sediment.

When finished, and tested for leaks, add inhibitor to prevent future corrosion.

Certainly both ends. You can usually purchase TRV/lockshield packs.

I have now swapped to the new Siemens trade trv and locksheild packs. Very impressed with quality and style and are also cheaper than any other make
