Heat Interface Units (HIUs)

The ModuSat® HIU draws energy from the main heating primary circuit delivered from a centralised plant room. This is in line with latest legislation encouraging the use of communal or district networks rather than the use of individual heating and hot water systems.

ModuSat® Heat Interface Units (HIU)

Our range of heat interface units, for Communal / District heating systems, are designed and developed by us in the UK and manufactured in our own production facility.

With a large range of models available, the system suits a variety of applications such as:

  • Small flats
  • Communal housing developments
  • Large luxury apartments
  • Sheltered accommodation
  • Student accommodation

Sometimes referred to as a heat board, HIU, heat interface or a hydraulic interface unit, the ModuSat® consists of either high capacity heat exchangers for indirect and instantaneous hot water and heating production, or a single plate heat exchanger for the hydraulic break and an integrated fast recovery DHW tank.

Similar to a domestic size boiler our unit features all the necessary equipment to provide the apartment with heating and hot water, including heating circulation pump, control valves, blending valve, pressure relief valves and electronic control board.

ModuSat® XR has been independently tested against the latest BESA (British Engineering Services Association) HIU performance regime. The results demonstrate that the units surpassed benchmark requirements set out in the CIBSE /ADE Heat Network Code of Practice, for both duty and return temperature performance, and the unit offers impressive VWART figures.

Independent Control

The ModuSat® Heat Interface Unit design provides the end user with the same autonomy as if they had their own boiler and tank. This includes a meter for billing of energy usage and cold water consumption for each apartment or house, and where required it also offers a facility for both heating and cooling.

Metering & Billing

The in-built energy meter can be tailored to meet the requirements of the building operator and residents, including a complete remote billing solution using Bus, Ethernet or GPRS communication to provide the end user with a fully itemised energy bill or our PaySmart® pre-payment debt-free solution. Visit the Energy Metering and Billing section of the site for full details of the various solutions we offer.
