An unvented hot water cylinder system is a large storage tank normally situated in the airing cupboard, which is used for storing and heating water. These types of systems are popular as they do not require a cold water cistern or tank in the loft.
The unvented cylinder does not require a vent pipe, and instead uses an expansion vessel located next to the cylinder, which can often be more space effective within the property if space is limited.
