  2. Vaillant Open Vent Boilers
CATEGORIES

VAILLANT OPEN VENT BOILERS

Conventional boilers can also commonly be referred to as regular boilers, open vent boilers, or heat-only boilers. Whilst there are many different names for this type of gas boiler, they refer to a boiler which provides central heating and hot water through a hot water cylinder, often installed in an airing cupboard, and a cold water tank which is usually installed in the loft.

A regular boiler is the perfect choice for larger households with multiple bathrooms, as they can provide a lot of hot water all at once. Browse our range of regular boilers below.
