Aladdin Autovent HV30C Chrome 1/2" BSP

The Aladdin HV30C fits to your radiator to automatically remove air. even a small amount of air in a radiator makes a boiler work harder to heat a room and uses more energy.  Removing the air allows the boiler to work more efficiently saving energy & money.
An Aladdin Autovent keeps your radiator hot to the top. Air in radiators collects at the top of a radiator which makes it cold. Fitting an Autovent removes the air keeping the radiator hot.
Air in the radiator also causes corrosion in the heating system which can shorten your boiler and radiator's life. Each Aladdin Autovent also comes with a 5 year guarantee.
Aladdin Autovents can be fitted in any orientation - vertical, horizontal or even upside down.
There are various sizes of Autovent which will fit most radiators.  The most common size in the UK is the HV30C 1/2" BSP there are two models for this size - the HV30C (listed here) which has a removeable cartridge (at the end of the valve's life only the cartridge is replaced) or the HV30 model this is a complete valve (the whole thing is replaced at the end of it's life).
With a ½” BSP thread, the threaded hole in the tapping at the top of the radiator is 3/4" (approximately 20mm) diameter. It is easy to be confused with "BSP" thread sizes because the actual thread size is always 1/4" larger than the stated size. hence 1/2" BSP measures 3/4"!
Installing the valves is a simple DIY job that doesn’t require system draining. Once the valves are installed the changing of the cartridge is a ‘less than one minute’ operation.
