Unvented Hot Water Systems

Unvented hot water systems are becoming more and more popular, with a lot of customers changing their existing open vented hot water system to them.

The basic difference between the high pressure unvented systems and a traditional low pressure vented system is that we no longer require the cold water storage cistern, open vent pipe or cold feed pipe.

Instead, the unvented unit is fed direct from the mains cold water supply via a pressure reducing valve, preset to the relevant manufacturer’s specified pressures. Hot water drawn from the unit is then replenished from the mains supply.

To maximize the benefits of the unvented system, a sealed heating system, if applicable, can also be installed providing the boiler used is compatible.
