The stylish and versatile range of Aladdin Hygroseal™ automatic radiator de-aeration valves are a new breed in automatic radiator venting. By having air in your system, your heating system has to work much harder to achieve the desired temperature, resulting in higher energy consumption and increased bills. This lever mechanism may be simply, almost crudely, made of a pressed steel strip which acts as a bending hinge.

Experience more efficient heating, lower energy consumption, and save money with radiator bleeding valves. The valves are normally installed with the first installation of a system, then remain in place for the life of the system. For various reasons, hot water heating systems can accumulate pockets of air in the top of the radiators. Our products include 2 x Radiator Bleed Key Air Vent Clock Type, 1/2 Inch Universal Automatic Air Vent With Cut-off Ending Valve Cap, Radiator Reducing Bushes Installation Set, and many more. The valves are fully automatic, requiring no manual adjustment, and will not leak in the unlikely event of failure.All of our rails can replace the existing radiator in the bathroom and provide a stunning modern look with plenty of space to dry and warm towels.

Perfect for saving money while making your home that much more efficient, you'll be surprised at just how practical these little valves can be! I saw the video of this being tested at a lot of pressure way over the limit in a normal heating system and it did not leak.They mention that it is easy to fit and the heat is there every time, the radiator now stays full and warm, and the system runs better and with less noise. I have noticed a valve that has drops on it occasionally, its one of the screwdriver on/off valves but would be in a pig of a position to replace as its between two soldered pipes.

The innovative Hygroseal™ technology (patent pending) utilises a ‘dual-seal positive valve closure’ which provides an extended, leak-free life. Update after nearly 3 years, even though these have a 5 year warranty it says on the packaging , mine stopped working now just under 3 years from new. If your system is unvented, and you have a constant problem with "air" in a rad, then i would assume that it is drawn in from the negative side of the pump. The innovative Hydro-seal technology utilizes a ‘dual-seal positive valve closure’ which provides an extended, leak-free life.

I was just intrigued (sad I know) how this type works and is there anything to go wrong inside them. At the other end there will be either a wheelhead valve which can be turned off by hand or a thermostatic valve which should be turned to zero. Each product offers high-quality materials and durable construction, ensuring long-lasting performance.

Within a day all noises eliminated, all rads hot, hours spent bleeding rads a thing of the past, best few quid i ever spent, great product. Though it may take a little while initially for the valves to vent all the air, it is vital to be patient and avoid manually bleeding your radiators. The valves are fully automatic, requiring no manual adjustment, and will not leak in the unlikely event of failure as a backup failure safety mechanism is incorporated.
