How It Works

Open vent boilers, which are also known as heat-only work by storing hot water in a cylinder, which is usually located in an airing cupboard. There is also typically a cold water tank in the loft. Open vent system can serve any type of dwelling well, especially those that may have a high demand for hot water at certain times of the day.

Unlike the combi boiler which will lose water pressure if more than one or two hot taps are running at once, the open vent system can handle this well due to the hot water storage. This does mean that programmable controls are needed so your boiler knows when to start filling the hot water cylinder.
