To capitalise on the benefits that heat networks offer…

It’s vital for systems to be designed and delivered with installation, performance, end user control and ongoing maintenance in mind.

This includes the heat interface unit (HIU) that’s installed in each home to provide independent heating and domestic hot water, similar to a traditional boiler, but powered by centralised plant.

Find out more about our EDGE range of heat interface units below.

EDGE-T

Twin plate heat interface units with indirect space heating and instantaneous domestic hot water.

  • Twin plate heat exchanger
  • Indirect space heating
  • Instantaneous domestic hot water
  • Tested to BESA Standard*
  • One of the most efficient HIUs in the market
  • Most popular model in the range, designed for typical heat network systems
  • Equivalent to a combi boiler in terms of performance and functionality
  • Suited to homes with one to four beds
EDGE C heat interface unit

EDGE-C

Single plate heat interface units with indirect space heating and direct cylinder feed for DHW.

  • Single plate heat exchanger
  • Indirect space heating
  • Direct cylinder feed
  • Suited to applications where:
    Stored hot water is more practical or desirable.
    A secondary return system is being used.
EDGE D heat interface unit

EDGE-D

Single plate heat interface units with indirect domestic hot water and direct space heating.

  • Single plate heat exchanger
  • Direct space heating
  • Instantaneous domestic hot water
  • Cost effective solution as no waste pipe is required from heating system Pressure Relief Valve (PRV).
  • Suited to care homes and retirement properties where the risk of heating system damage is low.
EDGE S heat interface unit

EDGE-S

Single plate heat interface units with indirect space heating only.

  • Single plate heat exchanger
  • Indirect space heating
  • Typically suited to:
    Retrofit applications.
    Where an S or Y plan system is being used

Independently Tested to the BESA Standard

EDGE T1 HIU is tested to the BESA UK Standard for Heat Interface Units (2020) with published results.

VWART: 28°C / 29°C
(High / Low temperature test)

*EDGE T2 HIU will undergo the latest BESA test (2023) imminently.

Official results can be found on the BESA website or in the download section below.
