The HIU provides domestic hot water and space heating to properties that are serviced from district heating or centralised boiler plants. Supplied with or without heat meters.

These units comprise two heat exchangers, one for providing instant domestic hot water (DHW) at a regulated temperature and the second for space heating within the property. The unit is indirect so the primary heating circuit is hydraulically separated from the property space heating by a plate heat exchanger and operates only when DHW or space heating is required.
