HIU – What Is A Heat Interface Unit?

HIU: this is a component that is central to modern heating, cooling and hot water systems that rewrite the book on heating installation for communal and district heating requirements.

Traditional heating systems involve each building, or apartment within a building, having its own boiler and pipework to produce hot water and heating.

District or community heating changes this by creating the hot water centrally. The heat interface unit is then placed in the unit or building instead of a boiler, to control the flow of heat and hot water. The two are joined by a network of pipes. But why should new build developers consider this over more traditional forms of heat and hot water creation?

Improve Communal And District Heating With Renewable Energy

A primary consideration in the construction of new homes and mixed use developments is energy conservation using energy efficient heat networks. When using heat interface units, hot water, produced by a centralised communal heating plant, is delivered via heat exchangers, thus providing on-demand hot water and heating. The centralised heating plant can utilise renewable energy sources to do so, including solar thermal, biomass and CHP. The benefit of doing this centrally is that there is no need to equip each individual home or business unit with its own renewable energy source.

This cuts development and construction time, and saves money at every stage of development. Using heating units for apartments and other dwellings means there is no building-wide gas network to install; no gas connections in individual dwellings also means no flue pipes and no need for ventilation routes. Occupants and unit owners benefit from lower bills, but with no loss of power or control. Other benefits of the HUI approach include lower ongoing maintenance costs. One of the reasons for this is because there is only the one central boiler.

If you work with the right company, then the state of this boiler is remotely monitored continuously. This means that potential problems can be recognised earlier, dealt with quickly and the system returned to optimum working condition, without service interruption for residents.

Different Types Of Heat Interface Units For Your Development

If you are considering this type of community heating system for your next development, then you need to be aware of the different kinds of heat interface units that are available for your project. There are two main types of unit that can be distinguished by the type of heating they produce. These are direct and indirect heating.

Direct heat interface components facilitate a direct connection between the primary and secondary systems. A plate heat exchanger is responsible for providing hot water. In an indirect HIU, there is separation between the two systems.

Here, the plate heat exchanger transfers energy from the fluid in the primary system to fluid in the secondary system. If you are considering district or community heating systems as part of your next development, then it is important that you find the right provider to work with. Evinox Energy Ltd is one company that should be at the top of your contact list.
