Heat interface units, often known as HIU devices work as a bridge concerning the central boiler and the heating and scorching water methods within a property. These are generally mounted within large apartment blocks where you can have 1 central boiler method at times known as an energy centre which provides heating and warm h2o to all the block of flats. This not simply saves costs but will also maximises using Room accessible within Each individual flat.
Landlords have to Ensure that the heating and sizzling h2o methods are conveniently accessible for upkeep and inspection.
Heat Interface units might be supplied in a number of permutations to suit project, and budget. Products are meant to present both equally provide and metering of domestic scorching water (DHW) and / or Key heating drinking water.
Within the floor Heat Interface Units (HIUs) appear very similar to your conventional boiler, nonetheless, Participate in a really unique role in District Heating as spelled out beneath. HIUs Engage in a significant role since the pivot involving a central boiler and the recent h2o outlets in an individual apartment.
In this particular occasion it could be less difficult to combine very low to zero carbon systems in the central site; such as photo voltaic or HIU service London heat pump to pre-heat the chilly drinking water provide to direct gas fired h2o heaters. In these types of instances a heat only HIU, perhaps with a DHW meter, may represent essentially the most smart alternative.
Now we have a range of current market-leading and BIM-supported cold and hot alternatives to meet your needs.
Along with the heating-only HIU there is no facility to interface or measure DHW consumption, as a result the next group of HIU introduces warm h2o performance.
This heat interface device features Extraordinary adaptability of set up and distant controllable intelligent electronic features, meant to improve effectiveness with the procedure.
The HIU is oblique so the main heating circuit is hydraulically divided from the house House heating by a plate heat exchanger. The unit operates only when DHW or Room heating is necessary ensuring Electricity efficient operation.
When correctly applied, heat interface units offer a strong and economical Alternative to heating and very hot h2o shipping and delivery in modern, significant density, multidwelling developments.
Heat Interface Units (HIUs) are very similar in appearance to a typical boiler and are usually Utilized in the heat networks spelled out higher than. They work as a bridge in between the central boiler and the hot water shops in Every single apartment for example radiators, showers, kitchen area taps, and so forth.
The domestic warm water produced by the centralised boiler procedure — the hot drinking water that arrives outside of faucets and appliances — is transferred by way of heat exchangers, to offer Each individual apartment with on-need heating and incredibly hot h2o.
