What is a Heating Interface Unit?

Heat interface units (HIU) are a key component of communal and district heating systems.

They are responsible for transferring heat from a central or district heating network to individual residential and commercial properties, supplying on‑demand heating and hot water without the need for a traditional boiler.

 Trustindex verifies that the original source of the review is Google. HomeCert carried out an electrical safety test when I was moving home.  They completed the test and resolved some minor issues. Both the electricians that visited where great and exceptionally tidy. I would not hesitate to use again.
