Recieved two of these within 12hours of ordering, great! One for me and one for my mother, took minutes to fit

I take it you have fitted and used these before. Are they compatible with all rads?

My mums rads upstairs have never been right. shes freezing.

They have air back in within days, and cant bleed them herself.

So is this the solution?

How many do you get for £8 ? I noticed on Qvc last week the had a pack of these type of things less then £8 for five.

do they work?

OperateOnMe

... took minutes to fit



No draining required then? How does that work... oO

How do you fit them without bleeding the system ?..

Most radiators, as most have half inch fittings at the top. This is what I did
1. Turn off both valves on radiator, so its isolated
2. With a mug and screwdriver bled radiator (you do not need to do this)
3. With a mug+cloth underneath and a spanner, unscrewed the nuts on either side at the top of the radiator (not the bottom!!!!!!!!)
4. Hand screwed these on, then tightened it with the spanner with half a turn
5. Turned the radiator back on, hey presto about 3minutes and done

I like DIY, for other it may take a couple of minutes longer
Tools required: mug/bowl and spanner

I've never seen these any cheaper

Can we please have a guide to how these are fitted and work. If bleeding a radiator lets the air out and then water, how does this work without causing leaks?

Also, how do you fit one without draining a radiator as surely there is water that will come flooding out when you remove a bolt to insert this.

Do you need this on every radiator or just one upstairs and one downstairs?

p.s. Ideally fit on the radiator which is nearest to the top of your house, so it covers the whole house and provides the most efficiency

You mean how do you fit without draining the system more like....And how long do they last 3-7 years! May as well say they last tree fiddy years. Bleeding radiators is such a simple job. I'm voting cold on this one

The price of the Vent Cap alone, now is £10.20

Looking at Toolstations web site, the extra chrome cap has to be bought seperatley for £7.98

so package price is now £10.20 + £7.98 = £18.18, just been that kind of day for me, missed another one.:|

that might have been a cheap chinese make that does not have cartridges but welded on and thus not that good

True!

On ebay and other sites you can find the non-cartridge versions, not on toolstation

Its a sale, hence the version with the cap has been reduced. Remember you have to order over £10 for free next day UK mainland delivery

You don't have to fit the shiny chrome cap if you do not want to! You only need to fit one, but depends on the pipes on your house to be precise.
For my mum's house, I fitted the valve on the radiator in the attic room and the cap on one of the radiators in the hallway just because it looked pretty

What I am not getting how you fit these, when obviously there will be pressure in the radiators and water flowing out?

Its a rubbish idea sadly. If you have air in your system, it can collect in any radiator. Indeed, it will head to the top of the first rad it gets into. So you'd need one on each rad. Also, its curing a problem that simply doesnt exist - radiators dont make air, you bleed it once and its done. You might get some washing round out of the pipes when you first turn it on, but its not something ive ever noticed, and ive moved a lot of rads and fitted a few full systems. Modern boilers have an auto vent built in anyway. Just bleed the buggers with a key or screwdriver and be done. It doesnt make your radiators hotter - when you have air in them, the top is cold and the bottom hot. If you cant feel a difference top to bottom, there isnt any air in it. It wont magically make your house hotter.

So the claim its green is ludicrous. You are basically sending hard earned pounds to china for nothing. This deal couldnt be any colder.

You turn off the valves on either side of the radiator before fitting, if you do not you will have a very large leak!
I posted my fitting instructions earlier ^^^

You can easily get away with one in the majority of central heating systems in the UK, assuming your boiler works well (fluid circulates and moves/dissolves gases). You are right, you can also get away with just bleeding the radiators too, no problems with that; but I'm often busy to do this regularly and my mother is elderly! Only new expensive boilers have auto-air vents built in.

It’s guaranteed to work for 3years, on both open and closed central heating systems
I’m presuming this is in hard water areas, for soft water areas or if you put certain chemicals into your central heating system, it is likely to last longer. On some of the forums I read before purchasing it said 5-7years!

On the packing it says Q&A nlbengineering.co.uk/

its actually hydrogen you end up bleeding out due to a chemical reaction created by corrosion. yes RUST!. black water from radiators and "air" at top means you probably need to replace your inhibitor.

As joelp says it's a solution to a problem that doesn't really exist. I only get air that needs bleeding out if I've done any work on my heating. Ten minutes and the whole house is done. No air gets back in

The black stuff in radiator water is predoninantly copper oxide and comes from the insides of the pipes.

I agree that in theory bleeding shouldn't be necessary, but occasionally it is.

After bleeding your radiators, if it's a pressurised system, it's important to check the correct pressure is maintained. Usually there'll be a pressure gauge somewhere and often this should be about 1 bar when cold.

Likewise, if you fit these valves check the pressure on a regular basis.

Tend to agree, even at this discount I am counting my radiators and doing the maths thinking they won't pay for themselves over time. Especially since I bleed them myself. Though my house has a fairly decent circuit and is well insulated. Not voting cold as this is still a 'deal' if you are dead set on wanting them - or maybe need them for someone who can't bleed their rads.

If you have a pressurised system I would advise against this as you will end up constantly topping up the pressure.
First step should be to make sure you have sufficient inhibitor additive in the system. This will help stop the air being created in the first place. I ditched the valve and topped up the inhibitor and after a few days settling down I hardly ever have to bleed.

Our flat has communal heating which goes off in late spring and on in autumn. I have one of these and hence each year the maintenance company do not have to gain access to let the air out on the random day they decide to turn the heating on.

I replace the blanking plate with one of these so at one end I have the manual valve and the other one of these.

Not on every radiator that would be silly. Just one normally.

You don't have to put one on every radiator !! Some systems have one radiator, generally the one at the highest point,..install this on that radiator. These are fab, and although quite often at this price..well done op for bringing this to the attention...

re pressurised systems..err boyles law..and hot rads are better than cool ones

I have something like this on a pipe near the pump. Was fitted when the central heating was installed.

Buying things from China is incredibly ungreen for a number of reasons.

Thanks!

??? what sort of maths are you doing? Are you assuming you need to buy only one ~£8
reduction in heating cost due to better efficiency per day (8 standard radiators, medium size boiler), minimum £0.01/day, likely £0.045 (2 adults and 1 child) in a house with average insulation...
Break even about 6months average or with minimum savings 3years, after which you make a net saving on your bill

Cost/maths wise its similar to investments in reflective radiator back panels/foil
Much more savings with larger boilers, less efficient/older boilers, more people in the house, larger houses, multiple boilers, older homes, poor insulation...

At the end of the day, for systems that already work well, a similar saving can be made if you are prepared to bleed radiators annually (cost of a radiator key is 50p-£1!!!!). Its when your system is not perfect or you expect work/want to guarantee reduced maintenance that these are useful.

Explain that to my mum who is sat in a freezing room as bleeding the rads only lasts a few days - and it needs doing again. She can't - as she has arthritic fingers. 2 sets of plumbers can't resolve the air issue.

Just because its no good for you - doesn't mean its no good. Why are people so selfish.

How many radiator keys do people buy?
Each year people play hunt the radiator key and probably buy a new one each year!
(Leaving aside the divorce cost of fighting with the wife "where did you put my radiator key I put it here?")

Next question: where do the radiator keys go?
My theory is that metal thieves have switched from stealing cable to radiator keys

One would not be adequate. If it was, people would only need to bleed one radiator when filling their system. You obviously need to bleed them all.

couldnt agree more - just an expensive gimmick as rads shouldnt need bleeding more than once a year. Any more than that, then cure the underlying problem.

Then your Mum needs a plumber as there is a big problem with her system if that much air is getting in every few days. I cant fathom your logic thats its being selfish to educate ignorant people either.
