3/8" Hygroscopic Air Vent 508031

Say Goodbye to Gurgling Radiators & Hello to Efficient Heating!

Fed up with cold spots on your radiators or those annoying gurgling sounds from your heating system? This clever little 3/8" Hygroscopic Air Vent is designed to automatically release trapped air, helping your heating run more efficiently and quietly, making your home that bit more comfortable.

Banish Trapped Air for a Warmer, Quieter Home

At Heating And Plumbing World, we know an efficient heating system is key to a happy home. Trapped air is a common culprit for cold spots, gurgling noises, and reduced efficiency, making your boiler (perhaps from Andrews or Morco) work harder. The 3/8" Hygroscopic Air Vent 508031 offers a straightforward solution to these common issues.

This specific 3/8" Hygroscopic Air Vent, a type of Automatic Air Vent 3/8", uses a smart hygroscopic principle. Internal fibre washers contract when dry (allowing air to escape) and swell when wet (sealing the vent to prevent water leaks). It’s a 'fit and forget' solution, meaning no more manual radiator bleeding! Imagine your radiators heating fully and evenly, perhaps managed by your Honeywell or EPH Controls system.

Installing an Automatic Air Vent 3/8" like this makes a big difference. It continuously removes air, boosting system performance and warmth. This also helps reduce internal corrosion by expelling oxygen, protecting your investment in components like pumps (from Grundfos or Lowara) and expansion vessels.

Designed for easy installation on radiators or pipework high points, its common 3/8" size makes it a straightforward replacement. If you're doing any plumbing work with fittings or Polypipe products, consider upgrading. We also stock items from Danfoss, Myson, and Gledhill.
