Collection: Open Vent Boiler
An open vent boiler, also known as a regular or conventional boiler, is a type of boiler that relies on a feed (usually located in the loft) and a hot water cylinder to provide hot water for a property. The system is open to the atmosphere, meaning the feed is not sealed and maintains a connection to the outside air. This type of system is commonly found in older properties and is often selected for larger homes with higher hot water demands.
-
Open to the Atmosphere:
The key characteristic of an open vent boiler is the open feed and expansion tank, which allows air to enter the system. This tank is typically located in the loft or attic space
Hot Water Cylinder:
Open vent systems usually include a separate hot water cylinder (or storage tank) to store heated water, often found in an airing cupboard
Heat-Only Boiler:
Open vent systems are typically paired with heat-only boilers, meaning the boiler only heats water for the radiators and hot water cylinder, not for immediate use like a combi boiler
Suitable for Larger Properties:
Because of the hot water storage tank, open vent systems can handle higher hot water demands, making them a good choice for larger homes with multiple bathrooms
Potential Drawbacks:
One potential drawback is that the open vent system can be more susceptible to heat loss and may require more maintenance due to the presence of the feed and expansion tank. However, they are generally reliable and provide a steady supply of hot water
