Emergency HIU repairs

A heat interface unit (HIU) can breakdown at any time, leaving your residents without heating or hot water. With a first-time fix rate of 90%, a 24/7/365 call-out service, and restored supply within 24 hours where possible, your residents will be in good hands.

Planned HIU servicing

The heat interface unit (HIU) is the biggest component of a heat network inside an individual dwelling. It is key that there is no build-up of limescale, no leaks, and defective parts are replaced instantly to ensure each HIU consumes energy in the most efficient manner. Our heat engineers cover all of these aspects and more within our planned maintenance services.
