The use of HIUs can help deliver much more correct readings of Electricity use for individual consumers. This is particularly critical for the people in flats or social housing, where by it's got Traditionally been pretty challenging to precisely measure Vitality usage for each resident.
Because of the specifically developed four-option bypass Command, the Calefa, which by now delivers a very very low VWART will reduce the Electricity employed by even more throughout small desire intervals .
Heat Interface units is often provided in several permutations to fit undertaking, and spending budget. Designs are designed to offer both of those offer and metering of domestic very hot water (DHW) and / or Main heating water.
Over the surface Heat Interface Units (HIUs) look similar to your standard boiler, even so, Participate in an extremely distinctive function in District Heating as discussed below. HIUs Engage in an important job as the pivot among a central boiler and the new drinking water retailers in someone apartment.
Single plate heat exchanger (PHEx) HIUs and HIUs with no PHEx Direct heating and indirect domestic warm drinking water – This kind of HIU maintains a plate heat exchanger for instant hot h2o but dispenses While using the Place heating plate together with the circulation pump and growth vessel. Because of this the main h2o from the creating passes through the radiators during the apartments, this has two key rewards, First of all it avoids the temperature fall (generally about 50C) across the plate heat exchanger HIU repair which makes low temperature devices employing heat pumps much more successful.
In the event you’d like more information on our heat interface units or our services then we’d be more than joyful that will help. You may Get hold of us throughout the channels below, or fill inside our Speak to type and we are going to get back again in contact with you as quickly as feasible.
