Twin Plate or ‘Indirect’ - A “twin plate HIU” is the most typical style of HIU in britain industry currently and is very related, in basic principle, to a combi boiler. The twin plate HIU gives fast domestic hot water and has a circulation pump and expansion vessel for the pressurised radiator or underfloor heating procedure.

The SATK22 HIU allows impartial Charge of heat regulation and domestic very hot water output in centralised heating methods or techniques served by district heating networks.

Our group of experts are always available to answer any inquiries you will have about our goods. Get in touch with us currently with the question.

For those who have a vulnerability that is manufactured even worse by not enough heat, we won’t disconnect your provide involving Oct and should. But please Be aware that should you run from credit score, this will likely necessarily mean you received’t have heating and warm h2o. We are going to provide you with A short lived heater if your heating method fails.

During this occasion it could be less difficult to combine lower to zero carbon technologies within a central area; as an example solar or heat pump to pre-heat the chilly h2o offer to direct gas fired h2o heaters. In these occasions a heat only HIU, Most likely that has a DHW meter, may possibly depict by far the most smart alternative.

In comparison to the standard approach of particular person systems in dwellings, there are numerous Gains using a central plant tactic incorporating HIUs:

The HIU can basically be wall-mounted with the right fixings in two easy access keyholes. When the connections are created, there’s no want for virtually any programming, as once the technique is turned on, the Command unit begins quickly and is ready to use right after just a couple seconds.

Every household or condominium has its own HIU set up, which employs heat dispersed within the central community to deliver heating and domestic hot water (DHW) for use in the house, completely changing the need for individual boilers in Each and every home. To the end user it’s much like possessing HIU service a boiler as typical but without the flame.

Single plate large output HIU’s cater in your larger central heating needs. These can be obtained as particular person units, but will also be body mounted with several other HiFlow modules to create a modular substation. (see District heating substations)

Single plate HIU and perhaps by far the most compact HIU of its form available on the market, delivering domestic incredibly hot h2o and immediate central heating.

An HIU, from time to time generally known as a ‘heat box’, is an built-in Alternative for offering and recording the heat eaten by a person dwelling served from a centralised heating plant or district heating scheme.
