What is a Heat Interface Unit – HIU Repair Services

 

HIU Units are commonly fitted in flats and apartment blocks. A heat interface unit (HIU) does a similar job to a domestic boiler but takes its heat from central source and distributes it to the property via a heat exchanger.

The unit also measures the amount of heat delivered for heating and hot water. The unit is an efficient way to distribute heating and hot water. It has the advantage that it does not require a flue unlike a gas boiler and is therefore safer.

Inside the HIU it comprises of a heat exchanger, heat meter, expansion vessel, pumps, valves and electronics. A regular HIU service is required to keep the unit working a maximum efficiency.

We can provide HIU service for individual units but you may find it more cost-effective to book a service for multiple units in the same location at the same time. Please give us a call for a quote.
