What Is an HIU?

A heat interface unit (HIU) is used in buildings with communal or district heating networks.

Instead of each property having its own boiler, the HIU acts as the link between the central energy source and the individual dwelling, providing heating and hot water on demand.

HIUs are essential for:

  • Efficient energy transfer from central systems.

  • Accurate heat and hot water supply to individual properties.

  • Billing and consumption monitoring in multi-unit developments.

Because of their central role, regular HIU maintenance is critical to ensure consistent performance and to prevent costly breakdowns.
