This lends alone properly to projects which include apartments and social housing which would ordinarily have to have several smaller boilers.
HIUs like those made by Altecnic include 1 or 2-plate heat exchangers to transfer the heat within the central technique into instantaneous heating and very hot drinking water as and when it is necessary.
We are able to explore your venture and demands and assistance offer the information, abilities and professionalism you need to change Concepts into fact.
The BESA UK Examination Routine should be to symbolize the passions of buyers – this explicitly consists of conclusion consumers as They may be the ones that reward the most from possessing an successful DH procedure.
Our techincal specification sheet for our typical array of heat interface units can be downloaded by clicking below Mibec Compact HIU
Some tenants could get freezing water, Some others could get scalding water off the faucet. This is often risky for small business as disappointed tenants will inevitably go away.

We now have unmatched working experience and understanding of heat community style, based mostly upon a lot of Countless thriving installations throughout the UK, and can offer more accurate and economical utilisation of thermal energy in district heating environments.
You'll find variants obtainable around the heatingonly HIU basic principle, incorporating a two heating zone functionality for bigger dwellings, or maybe the inclusion of an adjustable balancing valve rather than an integral circulating HIU service pump, With this instance hydraulic structure of risers and distribution will differ (more on this later on).
HIUs (Heat Interface Units) are mounted inside particular person properties in a fancy in a similar manner being a boiler would be. The several heat interface units are then linked to a person central boiler via a program of pipes.
There is not any extra highway. There may be merely a selection: either we undertake additional eco-helpful technologies like HIUs, or we figure out how we’re going to apologise to our grandchildren for dropping the ball.
A decrease Total VWART represents a reduced typical annual return temperature from the HIU to the primary community and for that reason an improved doing HIU.
