Heat Networks
Our flexible range of Heat Interface Units (HIUs), heat stations and commercial heat pumps are perfect for the latest fourth and fifth generation heat networks. We also have the best performing heat pump-ready HIU on the market in the MTA Plus.

What is a heat network?
A heat network – also called district heating – is a distribution system of insulated pipes that takes heat from a central source and delivers it to a number of domestic or non-domestic buildings.
