Unvented Hot Water Systems Salford

Unvented Hot Water Systems Salford

Currently there are three main types of hot water systems in use in the UK; open vented, unvented and  instantaneous. Learn about the many benefits of unvented hot water systems installed by Gaswise Plumbing & Heating below.


UNVENTED HOT WATER SYSTEMS SALFORDThe principle contrast between high pressure unvented hot water systems Salford and a standard low pressure vented system is that we don’t need the cold water storage cistern, open vent pipe or cold feed pipe.

Rather, the unvented system is fed direct with the mains cold water supply with an inlet control group preset to the relevant manufacturers stipulated pressures. Warm water drawn from the unit is then replenished from your mains supply.

As water expands when hot and (as the title implies) there isn’t a vent pipe, the expanded water in the system is accommodated by either an exterior expansion vessel or, in the event of bubble-top units, an interior air bubble in the unit which is generated when the system is commissioned.

To maximise the main advantages of unvented hot water systems Salford, a sealed heating system, if applicable, will also be put in so long as the boiler employed is compatible.

The sizeable benefits to be gained from the installation of an unvented hot water storage system may be broken into two classes: benefits to the specifier/installer and benefits to the homeowner.
