ONSITE POWER MICRO POWER PLANT
The Radegast hostel in Prague with 70 beds uses supplies of heat and hot water from central heat distribution. After installation of one OnSite Power micro power plant with a total output of 92 kW, heating of water and rooms is primarily covered by in-house production, whereas central heat distribution is still a bivalent source of heating, used only during the winter when outside temperatures fall.
A point of interest about this installation is that greater savings have been achieved than expected, this being thanks to the decentralisation of hot water production directly on site. The original hot water supply system from a central source, which was established more than 25 years ago, is demanding on coverage of heat loss in distribution mains between production and consumption, this even being if hot water is not used (e.g. during the night).
This traditional system of central preparation of hot water is very inefficient and is practically no longer found in new systems. Nevertheless, there are still many buildings which have not been renovated and in which this uneconomical system is still in operation.
