Heat supply for a retirement home
Our project partner was tasked with developing an energy concept for a retirement home in order to achieve significant energy cost savings. The heat demand was approximately 600,000 kWh, and there were three self-sufficient heating systems in the building complex, which had been expanded several times.
Efficiently cushioning peak loads
On the heating side, a CHP unit was used to cover the base load, while a gas condensing boiler covers the peak load in the heating center. The heat is distributed to three stratified storage tanks with a total capacity of 6,000 liters, one of which is located in a separate building and is supplied directly from the largest of the three stratified storage tanks via a 70-meter-long district heating pipe.
For hygienic and efficient fresh water production, single-stage or two-stage drinking water heaters from ratiotherm are used in each of the storage tanks. In each building complex, a separate central controller regulates the system components—communication between them is controlled via a bus.
