Aladdin HV30 Self-Bleed Automatic Radiator Valve (

These work well and we have them on all our upstairs radiators and towel rails which means little to no bleeding in the house. Leak free and easy to swap out with a regular bleed point, they fit well with any radiator. Multi pack is good value

Each pack has 2 valves. Slightly cheaper at time of writing than buying them individually.Fitting is easy (assuming you are happy draining a central heating system! I suppose that's a bit of a caveat!)Drain your central heating in the normal way, get a really long wrench (longer = better = more torque and less possibility of damaging or mangling the valves you are removing), and apply very gentle pressure downwards to turn existing bleed valves (at top of rad) anti-clockwise. Warning, they might be messy with black grime when you remove them. I used some kitchen roll to clean the thread on the radiator before fitting the new ones. The new ones screwed right on, no problems. Applied a little pressure to tighten but it felt very obvious even for this novice plumber!I learned about these little things from a youtube bloke called "Ultimate Handyman" - generally trust everything this guy says. I have just drained my central heating system, plumbed a Magnafilter in, and at the same time fitted these Aladdin automatic bleed valves. When I filled the system back up from empty, it took 30 seconds! Normally I'd have to half-fill, run upstairs to a radiator to bleed it, run back down to the boiler and fill some more, each time stopping to run around the house to bleed rads. (Each time, risking spluttering dirty water on our nice white walls!)These things are frigging magic. Basically, no more running, just open the tap to let water into the system, stop when it's at 1.5 bars, and boom - all the rads work to their full efficiency all the time! No more bleeding rads, ever!I have fitted them onto 7 rads so far (all from one boiler) and plan to fit another 8 on our second heating boiler when I get around to it!

We just had our bathroom refitted, including a trendy new tall narrow radiator. It looks great, but the design of some of these, ours included, is flawed - they consist of vertical pipes with heatsink panels affixed to the front, which look great, but the pipes are only connected horizontally at the bottom and the very top, there are no horizontal pipes in between. This means that as soon as only a tiny amount of air has collected in the rad (our heating is old and we get a lot of air in the system, which collects in upstairs rads), enough to lower the water level just below the very top bar, the rad stops heating up completely, the hot water can only flow across the very bottom. Bleeding the rad and letting out what seems like a tiny amount of gas before it splutters water restores the flow across the top, and the rad heats up. So I fitted one of these, and it works perfectly, rad is now hot all the time.

Fitted a couple of these about a month ago and so far the do seem to be doing the job, after years of "cold top" rads upstairs I no longer have the weekly job of going round them all with a key.One was fitted to a radiator that was replaced last year, that job was easy ( 2 minutes) ..but..the other needed to go on one of the original 1980's radiators and THAT is the reason I can only give this product 4 stars. Maybe they should mention that it is NOT a fast fit on these elderly rads. Firstly, I had to file the end of the radiator to get it totally flat as these valves have a shoulder that has to seal on the end edge, and secondly, there was only just enough thread on the valve, just 5 mm more would've helped .. anyway, after a generous winding of PTFE tape, the job was done and it does work so overall pleased with the result.Would I recommend? of course, just that it may not be quite as easy if you don't have perfectly smooth ends on your radiators.UPDATE : a week after I wrote this, one of the valves seems to have stopped working and I have a half cold radiator again ( grrrr ), despite contacting the suppliers, to date I have had NO response from them so..maybe I was a little hasty to recommend??

I have a radiator upstairs that always seems to get air - I have tried troubleshooting it but get nowhere - and I ended up having to bleed it each day this Winter. Saw these, cheap so worth a go - and they work! Easy to fit into the radiator - just screws in - when you open the valves you can here air coming out of this unit and then a tiny drop of water as the top level is reached, and then that is it.Haven't had to bleed the radiator since...Very happy with it so have bought some more 'just in case'.

Fast delivery via amazon prime, perfect fit, easy installation, good quality, I must say I was a bit unsure if these would actually work, once fitted, no more bleed my radiators numerous times per week. Perfect.does the job perfectly

These worked as described. Bled the rads automatically. Very pleased with them and not having to do that manually.Been in for about three years now. No leaks and recently still auto bled.
