Open vented stored hot water systems

An open vent boiler is the existing system in most people’s homes. This type of system uses two water tanks, both located in the loft, and a hot water storage cylinder in the airing cupboard so it is very space hungry. One tank draws water from the mains supply and feeds the storage cylinder which, when heated by the boiler, can release hot water to taps all over the house.

The second tank is the feed and expansion tank which contains the correct level of water for your heating system, allowing for water expansion when you turn the heat on.

Showers, taps and running baths can be drawn in any room at the same time, but be aware that if the cylinder should run cold it will take a little time to reheat.

Many people switch from a traditional open vented boiler to an  sealed system boiler. This is a relatively cheap switch to make and will cut the need for one of the tanks in your loft.

Because it’s the existing system in many people’s homes, an open vented boiler is inexpensive to replace, although making the switch to a sealed boiler system is also relatively cheap. However, both these systems use up loft space as a tank is required to fill the cylinder.

Like system boilers, open vent systems allow you to run hot water from a range of outlets simultaneously, without the water running cold elsewhere in your house. The water pressure is low though, and you’ll only have drinkable water from one outlet, ecause it uses a storage system.
