Further information

  • This unit comprises of 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.
  • Our Heat Interface Unit (HIU) is the perfect solution for providing district hot water and space heating to properties which are serviced from district heating and applications with a centralised plant room.
  • The HIU is indirect so the primary heating circuit is hydraulically separated from the property space heating by a plate heat exchanger. The unit operates only when DHW or space heating is required ensuring energy efficient operation.
  • The HIU also comes complete with a first fix rail which allows for the system to be pre-plumbed before the unit is installed.
  • There are eight variants available.
