HIUS Explained

Your Guide to HIUS

Inta’s comprehensive range of products for heat interface units (HIUs) bring together software and hardware to meet the needs of specifiers, installers, landlords and residents.

What is a Heat Interface Unit (HIU)?

  • Heat Interface Units (HIUs) provide heating and hot water to individual properties connected to a district or heat network.
  • They are similar in size and appearance to a domestic boiler but do not generate heat themselves.
  • A central energy plant supplies hot water through insulated pipework to multiple buildings or apartments.
  • HIUs are installed in each property and connect directly to the central heating network.
  • They use one or two plate heat exchangers to produce instantaneous heating and domestic hot water on demand.
  • An electronic control unit optimises efficiency, improves response times, and manages system performance.
  • Modulating valves precisely control heating and hot water delivery for improved comfort and energy efficiency.
  • Thermally insulated casings help reduce heat loss and improve overall system efficiency.
  • HIUs are commonly used in apartment blocks, residential developments, educational facilities, and commercial buildings.

Benefits of Heat Interface Units (HIUs)

  • Instant hot water and heating on demand with fast response times.
  • Lower energy bills through improved energy efficiency and reduced heat waste.
  • No gas supply in the property, eliminating the risk of carbon monoxide from a domestic boiler.
  • Clear energy monitoring helps occupants understand and reduce their energy usage.
  • Reduced maintenance costs, with servicing focused on the central plant room rather than individual boilers.
  • Lower long-term costs for landlords and building operators.
  • Supports low-carbon heating, with compatibility for renewable energy sources such as CHP, biomass, solar thermal, and heat pumps.
  • Improved energy efficiency by producing hot water only when needed, avoiding the energy losses associated with stored hot water.

Where are HIU's installed?

Examples of how HIUs are used include:

  1. Providing central heating and hot water to individual rooms and dwellings within larger buildings such as apartment complexes.
  2. Providing individual residents and occupants better control over their heating and helps them receive more accurate billing.
