Aladdin HV30 Self-Bleed Automatic Radiator Valve (

Bought a two pack of these valves to replace ageing manual valves on two towel rail radiators. Being high in our system the two radiators needed bleeding more than any others and the bleed screws were wearing and I feared them snapping off. Our plumber recommended this type of bleed valve. The two new valves look to be of good quality, shiny chrome finish, and fitting was simple, a five minute job. No need to drain the system, I just shut off the inlet and outlet valves on each rad and swapped them out. A nice tight fit and a test showed no issues when the rad valves were opened up and the system fired up. I'll review the functionality of the valves to see if they work (ie no air build up) over the next few days/weeks and then update the review.

I changed out my central heating, going from copper pipes to Hep2o, and installed 6 new radiators (4 being tall ones). Since installing them, the heating has always been a bit noisy, gurgling sound in radiators, dripping sounds, etc. Tried draining the system and refilling (a few times), regular bleeding, adding inhibitor, adjusting the valves, but nothing seemed to work. Just recently I replaced all the radiators and TRVs again (like for like - the radiators I originally got had a manufacturing fault and the paint had started to blister after just 18 months). After this the sound seemed worse, and also got a very nasty new vibration sound in some of the radiators that was really loud, a slight turn of the TRV would make it stop. Tried bleeding again as this was suggested as a fix for the loud vibration noise from google research, balancing, all to no avail. These were a bit of a last ditch attempt and they have made a massive difference. Installation was really easy, installed them on the 4 tall radiators we have, taking about 10 minutes per radiator. Once installed there is nothing more to do except use heating as normal and let them do what they were designed to do. After the first night all noises from the radiators stopped, no more gurgling or dripping sound, no nasty vibration on the TRVs - amazed by them. The significant nose I hear now is from the boiler at the opposite end of the house! The heat output also seems to have improved a fair bit, but that could be due to the recent cold-spell making it appear to be throwing out more heat. Would really recommend them, at this price point and due to ease of installation they really are worth a try if you have a noisy system or want to see if you can get any improvements with heat output/efficiency.

I had some radiators added to my existing central heating system (over 15yrs old) and somehow the new setup made the system really noisy with air swirling thru pipes and two of my furthest upstairs radiators filling with air constantly. I was bleeding air from them weekly and then daily. My builder had no idea why this was happening but designed some other changes near the boiler to minimise the introduction of air in the system. It would be a little time consuming a few £100+ on my budget. Somehow I came across this product on an online forum and decided to try it. It was easy to install without any draining and although I only installed 1, it seems to have done the trick for me. Reduced noise (not completely) in the pipework and no more air to manual release from the radiators. I installed 1 on the opposite side to the Manual Air vent allowing the option to use this if the Aladdin fails. I did find however (just like another reviewer) that it took a few heating cycles for the air to completely vent, but 1 month-in , I am very impressed by this easy to DIY gadget.

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!

Very pleased with these bleed valves. Noisy system due to air accumulation fitted in literally 2 minutes and working great. Very pleased.

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.

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

Excellent product solved my problem and released the air from the radiators

Los purgadores se ven robustos y de momento funcionan bien. Tendrá que pasar un tiempo para ver si purgan las burbujas de aire del circuito.

In realtà ero scettico ma invece ottimo prodotto

Ich habe den Artikel in allen Heizkörpern seit mehreren Jahren im Einsatz und sie laufen problemlos. Werde die Heizkörper bei meinen Kindern mit der neuen Lieferung ebenfalls ausrüsten. Der Aladdin ist auf alle Fälle seinen Preis wert und ich kann ihn nur weiterempfehlen!!

Fonctionnement conforme à mes attentes; à voir dans le temps.

Moet ze nog installeren,...
