As is often viewed in Figure 4, components and hydraulic structure are mainly just like the heat-only variant, but Along with the introduction of a plate heat exchanger to allow instantaneous generation of DHW at each dwelling, in exactly the same way as a mix boiler. So as to create DHW in a valuable temperature and movement rate, the key very hot water feed onto the plate heat exchanger should be during the area of 75C. This can be at odds Along with the dwelling heating program operating regime where by, inside the occasion of underfloor heating as an example, the flow temperature essential might be Substantially reduced.
This lends alone properly to tasks like apartments and social housing which might typically involve numerous compact boilers.
It should however be comprehended which the HIU depends over the tertiary system (the radiators and or the underfloor heating) becoming appropriately controlled and, by way of example, it could possibly only do its position correctly When the radiators are well balanced!

Look at valves: Normal ball valves with crafted-in Examine valves Parts for heat pump systems
As A part of the start of our upcoming technology ICON HIU, we’re analyzing the purpose of HIUs in heat networks. In our initial site on the subject, we’ll be inquiring just what a Heat Interface Unit (HIU) is, and searching at the different types of HIU.
We have unmatched expertise and knowledge of heat network layout, dependent on quite a few thousands of successful installations through the entire UK, and can provide more accurate and efficient utilisation of thermal energy in district heating environments.
In case you demand more assistance getting the goods and services you're looking for, our dedicated staff of authorities are on hand that will help.
HIUs (Heat Interface Units) are installed inside of unique Qualities in a fancy in the exact same manner like a boiler might be. The multiple heat interface units are then linked to one central boiler through a program of pipes.
There is no extra street. There HIU repair exists only a option: both we adopt extra eco-helpful technologies like HIUs, or we determine how we’re going to apologise to our grandchildren for dropping the ball.
