Unvented Hot Water Systems Warrington
The principle distinction between high pressure unvented hot water systems Warrington and a typical low pressure vented system is that we will no longer need the cold water storage cistern, open vent pipe or cold feed pipe. n its place, the unvented system is fed direct through the mains cold water supply with an inlet control group preset to the relevant manufacturers described pressures. Warm water drawn from the unit is then refilled through the mains supply. http://heatingengineersinwarrington.co.uk/unvented-hot-water-systems-warrington/
