Recommendations for TRVs

[Truman]

Hello all, I'm just a householder getting a couple of quotes for a new CH install and am looking at which TRVs to specify, seeing as the guys I've had quote me so far so just use cheap no-name TRVs, but are happy to price for and fit any I may choose.

I'm looking for a decent brand that shuts off fully, rather than have to faff about with a decorators cap. The Drayton TRV4 seems well rated till you read about them becoming brittle quite quickly and in any case they don’t shut fully off. The Danfoss ras c2 also looked good till I had a closer look at one in a friends house and the pin was very flimsy (and in his case all gunked up).

So… I’d be grateful for any recommendations you can give.

If you don't fancy the danfos or drayton you wont be happy with anything else!!!

danfoss and have your system cleaned properly.
If its a new system you wont have to worry then.

If you look online for reviews you will never buy anything!

Danfoss all day

 

[bigman]

Pegler terriers are what the companies I worked for always fitted the pin is fairly substantial never found a leak on one sometimes seized up over summer though

 

[Millsy 82]

Danfoss or bulldog if somebody is on a budget.

Well that is very very true about online reviews! I've been reading countless threads about pressure drops/leaks after converting from open vented to sealed and am now in a mild state of paranoia about all my concealed pipework (underneath my entire downstairs chipboard floor)...

Anyway, the existing system would be cleaned with a Magnacleanse and then inhibitior added so maybe the Danfoss ras c2 would be ok on my system. Still welcome any other recommendations though

most good branded one will be fine, the cheap £3-5 ones will prob last a few years and then stop working or leak.

 

[darrenjames10]

I always use the Drayton`s, any TRV has the potential to stick but if you keep your system clean that will help.

 

[Kyle87]

Danfoss for me too

 

[Ray Stafford]

Drayton TRV4 if it was me.

Lots of nonsense posted in online reviews by people who don't know nearly as much as they think they do.

As I was reading this I honestly thought the sentence was going to end with "people don't know nearly as much as ME"


That would have been an epic post

Im with most of you guys Danfoss or Drayton , But recommend staying away from the cheaper ones (£5), Had a custard asked me to fit TRVs they bought thinking they got good deal @£5 and they realise when fitted not the same control in temp,,, Its the usual story you get what you pay for,

 

[Chris F]

Honeywell?? just to be different.

 

[stratplus]

Bulldogs (plumbcentre) £16 set or drayton.

Surely you mean 7.50 a set? Thats what i pay.

 

[kay-jay]

Ras-c's decent valves. West therms if want a cheaper option

Fit these for company, looked online for price sure they were 16??

 

[Truman]

Thanks for the tips. I've only got a couple of TRVs fitted at the minute, branded Alitech which I think is essentially a no-name brand. Will get these replaced when the system is done.

Anyone got experience with the Drayton RT212? Has a positive off, which I'm looking for, unlike the TRV4 which doesnt.

 

[IDCHAPPY]

Danfoss all day

Same here

 

[gasmanrob]

Comap/westherm

 

[morganb]

Big fan of Danfoss RAS-C2, just remember to fit them horizontally rather than vertically if you want them to work effectively.

 

[stratplus]

Same here

Danfoss expensive though?

thats like buying a BMW 1 series instead of a 7 series, because you prefer the colour of the carpet.

 

[Truman]

Can you get a Danfoss pack with a drain off lockshield? They only seem to be available with the standard lockshield.

Drayton TR4 are the kings of the TRV. If you can afford them, go for them.

What are those westherm lookalikey's like Ray? Any good. Having issues with bulldogs

They sell pretty well Tom, and the return rate is only a few per 1000 - IIRC about the same as Honeywell. But when I looked at the TRV4 figures the other day, we had not taken a single one back under warranty in a whole year. And we sell many thousands of them - and not a single return. I can't think of another technical product with a zero return rate.

 

[TBServices]

They look very nice for the price.

I've fitted TRV4 on all my parents radiators. Testify!

 

[Ray Stafford]

They look very nice for the price.

And they have the "A rated" tag which is very marketable. Not many TRV manufacturers seem to have taken the trouble to get theirs tested.

When our new book comes out next week, have a peek on page 35 for a new valve from Eastbrook. We think of them as being a bathroom company, but there is some cross over in the towel rails. They have a new towel rail valve that I reckon may take off in the mainstream heating market.

TRV? TRV on a towel rail = worlds biggest fail.

Depends on the system design surely?

It would have to be a massive towel rail in a tiny room to make the TRV close down

I have one of these



as well as a 600 x 800 k2 in my bathroom. The rad has a TRV4 on it, but the rail doesn't - but I wish it did sometimes. That bathroom can get like a flippin' sauna.

 

[TBServices]

That is also a radiator. When I say rail, I literally mean a towel warmer

Box of 10 is £65 ?

Zone vale it all up! I got one of the same and a 4 col and it's on a programmer stat and happily ticks over at 19.5
