Twin Plate or ‘Oblique’ - A “twin plate HIU” is the most common form of HIU in britain industry nowadays and may be very equivalent, in theory, to a combi boiler. The twin plate HIU supplies prompt domestic scorching h2o and it has a circulation pump and expansion vessel for your pressurised radiator or underfloor heating system.
Underneath no circumstance must you remove the duvet from your HIU or make an effort to tamper with any parts, as it could be risky, and could invalidate your agreement with us.
HIUs also supply on-demand heating, taking away the need for storage tanks and slower heating approaches. Residents can reap the benefits of rapidly heating, the two for central heating and drinking water.

There exists also fewer ongoing servicing needs for particular person dwellings, helping leverage economies of scale for almost any restore function.
Secondly, given that the HIU does not incorporate a 2nd plate heat exchanger, circulation pump and enlargement vessel the device is cheaper and often more compact. Immediate space heating does not surprisingly contain the downside of exposing the tertiary system (radiators) to Major network water, pressures, and temperatures, so any leak may not be restricted to just water inside the tertiary program, so care has to be taken to specify compatible tertiary components. Other advantages are that the tertiary procedure benefits from Key system h2o high-quality Command, no filling loop is necessary.

Together with the heating-only HIU there is no facility to interface or measure DHW usage, for that reason the 2nd classification of HIU introduces hot water functionality.
In the end, a heat interface device is An important Element of any communal or district heating technique. Used most frequently in condominium blocks and flats, it's to blame for offering the new h2o and heating inside a residence via a network of pipes which might be linked to 1 central process.

Single plate substantial output HIU’s cater for your personal bigger central heating demands. These are offered as individual units, but may also be frame mounted with many other HiFlow modules to make a modular substation. (see District heating substations)
Single plate HIU and perhaps quite possibly the most compact HIU of its type available, providing domestic sizzling drinking water and direct central heating.
Despite the use of a central gas boiler, district heating provides a possible chance to use renewable Strength sources including CHP, biomass, solar or heat pumps.
