Challenge of Flushing an HIU - Heat Link Technical Solutions

Since 2004 Heatlink has designed, manufactured and installed thousands of bespoke heat interface units for a plethora of schemes located throughout the UK.


Born from the increasing amount of request for a standardised HIU, Heatlink is now proud to offer two separate types of Standardised Heat Interface Units. The 3000t and 3000E.

Commissioning is a vital part of our process which ensures the correct functionality of the HIU and accuracy of the metering reading and billing scheme.
