All open vent and sealed system heating and hot water systems need a hot water cylinder (sometimes called a central heating storage cylinder), which is normally housed in your airing cupboard, wardrobe or bathroom.
Glow-worm provides a wide range of mains-fed unvented hot water cylinders that are designed to work with any UK boilers, not just the Glow-worm range, to give you a reliable storage cylinder central heating system.
Our hot water cylinders are incredibly robust and built to last. Each is manufactured from high grade stainless steel, with all seams laser welded and guaranteed against perforation of the steel shell for 25 years.
All Glow-worm unvented hot water cylinders also have excellent levels of insulation and quick heat recovery times, so you won't have to wait very long for a shower or a bath after someone has drained the tank.
Hot water cylinders are available in six sizes - 115, 150, 175, 200, 250 and 300 litres - and are suitable for all sizes of property, from a small flat with a single bathroom to a large property with two bathrooms and an en-suite shower room.
All models are 600mm wide at the widest point
