Heat Only Boilers
Open Vent Heat Only Gas Boilers
Open vent heat-only gas boilers, also known as regular or conventional boilers, are designed to work with a traditional heating system that includes both a hot water cylinder and a cold water storage tank (typically located in the loft). They are the ideal choice for replacing an existing open vent system, particularly in larger homes with high hot water demand or properties with multiple bathrooms.
Unlike combi boilers, heat-only boilers store hot water in a separate cylinder, allowing hot water to be drawn from multiple outlets simultaneously without a drop in pressure. This makes them well-suited to larger households where several taps or showers may be in use at the same time.
