HIU Heating Units: Why Install Them?

HIU heating units have certainly grown in popularity over the past five to 10 years.

That’s a major reason why so many developers are turning to heat interface units (or HIUs) to either provide a communal or district heating solution. So why are these systems so environmentally friendly?

Well, stats have shown that when people are aware of their energy consumption and have a way to check it easily, they are less likely to use excess energy. By installing a HIU in every property within a development or social housing area, it gives tenants the ability to see their own energy consumption which, in turn, will lead to energy savings.

It is not unheard of that certain properties or developments have reduced their carbon footprint by up to 30% through using such heating networks. As developers must abide by Governmental regulations on low and zero carbon options in new builds, HIUs can be fully designed and built with future-proof, renewable energy systems in mind.
