Advanced modular substation technology using sets of light commercial HIUs of up to 165kW (DHW) or 100kW (CH) each, combined through manifolds to provide much higher outputs,  greater redundancy, or a mix or services.

The most efficient heat interface units in the UK

HIU performance has a major impact on the operating efficiency of a heat network. Our NODE-iHIU Controllers are specifically designed maintain the best possible efficiency on every HIU.

Pioneering HIU design

Heatweb manufactured the very first electronic HIUs in the 90s. We continue to drive the industry forward through continuous product development and many unique, patent-protected features.

We have unmatched experience and understanding of heat network design, based upon many thousands of successful installations throughout the UK, and can provide more accurate and efficient utilisation of thermal energy in district heating environments.

HiFlow DHW Module

Single plate high output HIU’s cater for your larger hot water requirements. These are available as individual units, but can also be frame mounted with several other HiFlow modules to create a modular substation.

  • 165kW Domestic Hot Water

HiFlow CH Module

Single plate high output HIU’s cater for your larger central heating requirements. These are available as individual units, but can also be frame mounted with several other HiFlow modules to create a modular substation.

  • 125kW Indirect Central Heating

HiFlow  Heat Exchanger sets

Frame mounted single plate high output heat exchanger sets cater for your larger hot water or central heating requirements. These are available in banks of 2 to 6 heat exchangers.

  • 1MW Domestic hot water
  • 750kW Indirect central heating
(Note: DHW Outputs based on 70°C Primary Flow & 10-50°C Secondary Temperatures – CH Outputs based on 70°C Primary Flow & 65-35°C Secondary Temperatures)
