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.

Great product and does what it means.

Why did I not fit these earlier? Simple and easy to install (whilst your radiator is full of air isolate at the in/outlet valves and swap the ends over). They use some sort of plumbing ‘magic’ to let the air escape but not the water and saves me a lot of bother as I was continually bleeding air that accumulates in the radiator nearest to the boiler which runs cold. Less air in the pipes and the whole system runs more efficiently!

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.

Order came next day, well packaged (Amazon) seems good quality, yet to fit yet, but reviews seem good 👍👌

In realtà ero scettico ma invece ottimo prodotto

Es lo que buscaba hace tiempo. Se pone fácilmente queda muy bien en el toallero y funciona a la perfección. Lo recomiendo. Ni siquiera an tiendas de fontanería sabían darme una solución para sacar el aire automático del toallero.

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!!

Tres content de mon achat. En plus j ai un circuit de chauffage avec des hauts et des bas. Apres installation des purgeurs nous avons une chaleur uniforme sur la superficie de radiateurs, et des pièces qui chauffent plus vite a la cause de normalité je pense. Finis avec la purge manuelle. Produit très pratique Merci a vous,

Moet ze nog installeren,...
