The choice on which kind of HIU to employ will mainly be informed by the overall building energy method. If sufficient CO2 mitigation is A part of the space heating provision, then HIUs incorporating DHW output by using a plate heat exchanger could possibly be the best option. However, given that the predominant Vitality need in new properties tends to be incredibly hot drinking water output, it could be necessary to address different Area heating and warm h2o tactics.
If heating and DHW HIUs are proposed, then It will probably be necessary to distribute from central plant at 75C to 85C.

Next, as being the HIU doesn't incorporate a second plate heat exchanger, circulation pump and growth vessel the unit is much less expensive and often smaller. Direct space heating does needless to say hold the drawback of exposing the tertiary program (radiators) to Principal network water, pressures, and temperatures, so any leak might not be restricted to just h2o during the tertiary procedure, so treatment need to be taken to specify suitable tertiary elements. Other benefits are that the tertiary procedure benefits from Most important procedure drinking water top quality Handle, no filling loop is needed.

It is crucial to obtain your heat interface units serviced routinely by qualified engineers as this will not only guarantee your process’s general performance All year long and extend the lifetime from the technologies, but it may also help you save you funds on repairs as most elements are coated by guarantee for about 10 to fifteen a long time!
Direct HIUs – The first HIU and for many years, prior to the introduction of braised plate heat exchangers, the only selection. These HIUs do not have plate heat exchangers and also have immediate connections towards the Place heating and domestic scorching drinking water systems. These techniques normally had particularly fundamental controls, heating may possibly Danfoss HIU service have been controlled with the building operator or just one motorised 2 port valve operated by a mechanical thermostat in the condominium and a mechanical ‘Tapstat’ to control the circulation with the community for domestic hot water cylinder. Some techniques relied over a centralised incredibly hot h2o cylinder for distribution to multiple customers.
Significant efficiency hydraulic [heat] interface units (HIUs) for the availability and control of heating and hot h2o to domestic and industrial Attributes connected to a district heating process.
With our prosperity of data and experience, we can help you to make the ideal squander h2o solution to your upcoming project.
When compared to conventional personal heating programs, HIUs current increased Added benefits to both of those landlords and tenants. When made use of with centralised heating systems, heat interface units might have the subsequent pros:
You will find there's heat meter Within the HIU. The heat meter measures how much heat Electrical power you employ. Heat is measured in kilowatts, demonstrated as kWh in your assertion.
