A little information about Heat Interface Units.

Heat Interface Units (HIUs) provide central heating, and domestic hot water, the hot water can be created directly using a twin plate unit, or a single plate unit with use of an Unvented cylinder. They will serve individual properties within a multi dwelling development fed by a centralised heating plant.


An overview of district and community heating and Hot water

District heating supplies heat from a central source to a variety of buildings – which might include houses, blocks of flats or apartments, the heat is delivered through a network of pipes carrying hot water. communal heating follows the same principle, but on a smaller scale – sometimes serving a single block of residential flats or apartments.

The Energy consumed by an HIU for individual households or apartments is recorded by a meter, this makes them very attractive for those operating a large portfolio of developments or single dwellings. Meter readings can even be carried out remotely, making HIUs a much more viable option for landlords, who can then bill their tenants. Metering can also be a positive incentive for occupants trying to lower their energy consumption and keep their energy bills low.
