Twin Plate or ‘Indirect’ - A “twin plate HIU” is the most typical form 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 process.

In these kinds of circumstances a buffer vessel within the central plant room can be integrated to smooth out peaks in desire pattern, lower peak plant loads and cut down boiler capability.

The effects replicate the predicted impact with the HIU in various operating modes, mimicking the needs they may hope to knowledge throughout a calendar year in a typical new Make development.
As maintenance and mend are focussed around the central plant place against person boilers in Each individual dwelling, extended-expression cost discounts could be obtained.
Expertise all the benefits of heat interface units (HUIs) from Ecolution. Our robust scorching water devices and communal heating supply hot water and suitable central heating to multi-dwelling tenants on demand from customers. Supply for their heating demands and lower your making’s carbon footprint — check with us how.
It is necessary to own your heat interface units serviced usually by experienced engineers as this will likely not merely guarantee your method’s overall performance All year long and extend the lifetime of the technological know-how, but it really can even preserve you cash on repairs as most pieces are protected by warranty for roughly 10 to fifteen a long time!
We've got unmatched practical experience and idea of heat community design, primarily based upon numerous 1000s of prosperous installations through the British isles, and can offer additional precise and successful utilisation of thermal Electricity in district heating environments.
A further variation is usually a heating only device with the inbuilt DHW litre counter, thereby allowing for a centralised warm drinking HIU service water method but with the ability to observe and cost for nearby use within just Every single dwelling.
Plainly this brings about a tremendous disparity amongst heating and incredibly hot drinking water loads, so designers should study and undertake correct variety aspects when identifying plant capacity, in order to get there at a cheap and energy economical Alternative. Usually occupant lifestyles and usual use profiles will ascertain the suitable range issue.
When deriving pipework distribution and pump measurements, it is usually recommended that horizontal branches at Every single ground amount are piped inside a reverse return format, both to help with hydraulic balancing and to be certain even distribution of heat among dwellings (see Determine five).
An HIU, occasionally known as a ‘heat box’, is surely an integrated Remedy for providing and recording the heat consumed by an individual dwelling served from the centralised heating plant or district heating plan.
