Twin Plate or ‘Indirect’ - A “twin plate HIU” is the most typical variety of HIU in the UK market place right now and is quite equivalent, in theory, to the combi boiler. The twin plate HIU offers immediate domestic hot water and has a circulation pump and growth vessel to get a pressurised radiator or underfloor heating process.
The SATK22 HIU permits unbiased control of heat regulation and domestic warm drinking water production within just centralised heating methods or units served by district heating networks.
If heating and DHW HIUs are proposed, then it will be necessary to distribute from central plant at 75C to 85C.
This gets rid of the need to put in particular person boilers in Just about every dwelling, generating the two cash-preserving and Electricity-conserving possibilities among many other Gains.
Although it is feasible to install a boiler in each individual device of the multi-dwelling creating, doing so would need many time, labour, fiscal assets and ground Place. This can be problematic for numerous matters:
HIUs are installed into Each individual residence while in the creating as a boiler would be. The device is linked to just one central boiler through a community of pipes.

Together with the heating-only HIU there is not any facility to interface or evaluate DHW use, hence the second classification of HIU introduces hot water functionality.
By increasing the effectiveness of Electricity usage, HIUs and district heating supply a simple Answer for any greener tomorrow.
A unique range of HIUs, together with the two conventional and custom made products, known to get consistently by far the most efficient out there – as independently analyzed
When it comes to how the Heat Interface Units are managed, There are 2 attainable Manage styles, thermostatic and proportional hydraulic.
