Heat Interface Unit (HIU) Services
HIUs are the link between your central plant and every dwelling on a heat network. When they work well, the whole network does.
On a heat network (district heating), each property has a heat interface unit instead of its own boiler. The HIU takes heat from the central plant through insulated pipework and turns it into instant heating and hot water.
Networks are cheaper to run, save space and work with low-carbon sources such as CHP, biomass, solar and heat pumps. All of that depends on every HIU being set up correctly. One badly set unit can drag return temperatures up across the whole network.

FAQ
Questions we get asked
Do you work for housing providers?
Yes. We work with housing associations, managing agents and developers on HIU servicing across their sites.
How often should our equipment be serviced?
At least once a year. Ideally heating in autumn and air conditioning in spring. Oil-fired equipment really should be cleaned and serviced every year.
Why service if nothing is wrong?
Better reliability, problems caught early, lower running costs, longer equipment life and a safer building. It's also usually a legal requirement.
