HV30 Aladdin Self Bleeding Automatic Radiator Valve 1/2" BSP Single Valve

Product Information

However, for modern radiators with standard slotted screws in their bleed valves, a flat-headed screwdriver will do the job just as well if you don’t have a key. If your radiator is of the older variety or features a different kind of bleed screw, for example, a hexagonal or square knob, you can try an Allen key or radiator spanner. To bleed a radiator, you need to first identify that it is a hot water radiator (rather than a steam-based one), turn off your central heating to avoid scalding, lay down towels to protect against water damage, and use a bleed key to open the bleed valve in your radiator, to release the trapped air inside.

Find a radiator key. If you've decided to bleed your radiator your first step should be to find something to open the radiator's "bleed valve." Look for a small valve at the top of one end of your radiator. On this valve, there will usually be small square bit which can be turned to adjust the valve. Radiator keys, cheap metal implements designed for opening and closing radiator valves, are available at most hardware stores. Find a radiator key that's the correct size for your valve or, alternatively, search your tool chest for a small wrench or other tool that's the right size to turn the valve. [3] X Research source If you have a modern radiator then this should be simple but on old radiators, you might have to replace the radiator. If the valve body is filled with water, the float moves upwards and closes the valve. If air collects in the valve body, the waterline lowers, as does the float, and the valve opens to release it. [4] To give more sealing force on the valve, the float generally works the valve through a lever. A greater movement of the float gives a shorter, but more forceful, movement of the valve. This lever mechanism may be simply, almost crudely, made of a pressed steel strip which acts as a bending hinge. [5]

The HV30 model or OEM model (Original Equipment Manufacturer) is a lower cost ½” BSP version with exactly the same mechanism inside, lasting the same amount of time. Locate and loosen your car's bleeder valve. Some cars have bleeder valves incorporated into the cooling system which function by releasing trapped air, just like the bleeder valves on a home radiator. Consult your owner's manual to find the precise location of this valve - usually it's located at your cooling system's highest point to most effectively release air, which naturally rises. [12] X Research source Sometimes found on older radiator models, a bleed screw doesn’t have a valve to replace or remove. Instead, you will find a small screw on its own. They’ll be in different locations depending on the radiator but will commonly be found at either the top right or top left. It is possible to replace these but more often than not when you have a problem with one of these, it's time for a new radiator instead. Screw valve Air in a radiator can cause serious problems with both heating and corrosion. A mere two inches of air in your standard household radiator can result in up to 75% heating inefficiency. By automatically evacuating unwanted air from your radiators Aladdin autovents not only help to reduce energy and heating costs, but they also extend the lifetime of your central heating system components by reducing the chance of metal corrosion.

Bleeding radiators, while hot water is still running through the system, increase the danger of scalds and burns, therefore you should never do it when the heating is on and the system is still hot. Which Radiators Do I Bleed First? Make sure you have a simple cloth rag to hand when you’re bleeding your radiator. This is because as soon as you have bled the air out of your radiator, the water that now has room to rise will start dripping out, and you’ll need something to catch it. The rag can also help create enough friction to turn the bleed valve if it’s particularly tight. Old towels and dust sheets Air vents on steam radiators often get accidentally painted over, which can clog them up and stop them from working properly. If this has happened, take a needle or strong piece of wire to poke through the obstruction and free the vent’s air holes. Turn on your central heatingThe new method, which I use myself, is the vacuum method. You need a vacuum tool for this and compressed air (depending on the tool) to use this method. If you can remove the old bleed valve or screw then replacing it is the best option most of the time. Some cars have one or more air bleed valves to get the air out from the system, and some cars don’t have this air bleed valve, which makes it a lot more difficult. The good news is: that you don’t need to pay a professional to bleed a radiator. It is a fairly simple procedure that you can do yourself, with just a couple of tools. Abnormally high temperature readings on your dashboard temperature meter. [10] X Expert Source Duston Maynes

Aladdin Autovents reduce the volume of air/gas in radiators and helps to maintain their thermal efficiency, thereby reducing the fuel and energy usage. The Micro Barlo fits ‘Roll-Top’ radiators. These have a rolled over steel smooth top to the radiator panel. The left and right edges are welded seams. One model has the bleed pin facing to the wall and on a double panel a second bleed pin also faces outwards.

Our Autovents have a unique patented design which means at the end of the product life they will seal shut. 5) Don’t all Automatic De-aeration valves leak? A typical radiator should bleed completely in no more than 20 to 30 seconds. This can change depending on the radiator’s size and the volume of trapped air. Continue to keep bleeding the radiator until water starts to flow from the bleed valve and the hissing sounds stops. This indicates that you have completely drained the radiator of the air.
