In all arrangements one of the primary drivers for the integration of HIUs is metering; the arrangements for this can differ with company but fall largely into two groups.
Crown Commercial Support (CCS) supports the public sector to attain optimum industrial worth when procuring frequent items and providers.
As district heating is basically focused on a central plantroom and one boiler, routine maintenance and servicing grow to be significantly less complicated and cost-effective. Setting up boilers in Just about every property could well be remarkably cost inefficient in comparison to a person remarkably effective central boiler.
The thermal interface unit materials water by using a substantial effectiveness plate heat exchanger , which gives higher levels of mains strain scorching drinking water up to 50kW. (Greater amounts out there if necessary)
