radiator TRV....... is cheap as good as expensive

[pspec]

Hi
I was looking at putting TRV on all my radiators when i noticed there is a huge price difference between them.


Would I be wrong in saying a £5 one would be just as effective as a £40 one.


I’m trying to work out why the price difference...yes i can see one may be build with better materials. But surely they must both turn the waterflow off at the set temperature.

Does anyone have any input...

thanks

The Bulldog brand in Plumbcentre are good quality,reasonably priced and reliable.

Honeywell all day long, reasonable and reliable. Cheap stuff will bite you!

Trv's come in 2 form Liquid or wax sensors. Liquid sensors like in Danfoss RasD or Drayton TRV4's are faster acting and more expensive.
Personally i prefer Danfoss. Used them for 30 years and never a problem apart from the odd sticking pin plus they are the only true bi directional valves on the market afaik.

Yes. You would be wrong.

But there is no reason to spend £40, unless you are looking at programmable heads, or possibly some of the up-market remote sensor versions.

Allow £15 - £20 per valve and get good Drayton, Honeywell, Danfoss or Pegler.

Same as Tamz, i prefer Danfoss

cheap valves like the £3-5 ones from screwifx etc.... will need replacing within a few years. Ive been back to several jobs a few years later where i fitted customer supplied cheap valves and had to replace with better made ones.

I tend to use the buldog one's from plumbs not bad for the money pegler make them ,as for the cheap one's as other's have said they leak in a few years time waste of money.

Even pegler chinese, sold on poo fix with different name 3squid

I went through a phase of ras-cs but have gone back to myson contract.

my own home is using some cheaper ones, no issues to date 13 years down the line

Myson are #*%# - trust me. I find they will hang around a lot of years but the pins stick in the bodies very very often & the thermostatic heads also very often fail closed (the plastic pin gets pushed down). The plastic base can go brittle with a lot if heat after a while & snap off. They look bulky & poor IMO also. I do a lot of repair work & it's the Myson TRVs that keep me busy.

Yorkshire Mistral are decent & cheap. Being going years & I don't see much wrong with them.
Westherm seem good.
Peglers Bulldog are decent enough & don't cost much but olives can be poor & the lockshields supplied with them are push on cap type cheap rubbish.
Trvs to me, are a part you replace on your heating about every 15 years perhaps max.

 

[tamz]

Thats cos you've pulled the heads off them lol

Probably because you haven't touched them in 13 years.

Anyway, how would you know if there was a problem?

You wouldn't go looking for one would you.

Hi

some great replies.......

Thanks guys

 

[PlumbExpert]

I agree with Tamz, Danfoss are good quality and very reliable.

Avoid Drayton rt212... Once these are turned to off posistion they bind shut & can't be opened again!!!!

Hi there pespec and welcome. It's the usual story. You get what you pay for, although a 14 quid set of Danfoss valves are as good as any of the more expensive ones. What I'd stay away from is the cheap non branded models. Common makes like Drayton , danfoss , honeywell etc will use serve u well but stay away from bargain 4 quid thermostatic valves like the ones screw fix sell as they are diabolical.

I was about to buy Drayton TRV4, but on the Drayton web site the technical specs say the their own much cheaper wax filled one reacts to temperature change at exactly the same rate as the more expensive liquid filled TRV4.
So I bought the cheap wax filled Draytons from Screwfix - no problems.

RAS-C every time for me

Turn them to 0 in 6 months & the valve won't open again without a pair of grips!!

I regularly turn mine off when windows open to air the rooms - no problems - those are 7 years old.

Also noticed they have the same body as the TRV4 - it is just the head that is different.

PS anyoe knw whyour kwyboard does not work on this site !!
