The Aladdin HV30C fits to your radiator and automatically removes air. Even a small amount of air makes your boiler work harder, wasting energy and money. By removing the air, your radiator heats fully to the top, your system runs more efficiently, and you save on bills.

Air in radiators also causes corrosion, reducing the life of your boiler and radiators. The Autovent helps prevent this and comes with a 5-year guarantee.

It can be fitted in any position—vertical, horizontal, or even upside down. The HV30C ½” BSP is the most common size in the UK and has a replaceable cartridge, so only the cartridge needs changing at the end of its life. The HV30 is the same size but replaced as a complete valve. (Note: ½” BSP threads measure ¾” across, about 20mm.)

Fitting is a quick DIY job with no draining required, and cartridge changes take less than a minute.

A simple, money-saving upgrade that keeps your home warmer and your heating system healthier.
