Domestic hot water for the DFAB Unit is provided by a heat pump boiler.

On the evaporator side, the heat pump boiler is connected to the return flow of the heating network of the DFAB Unit. The condensation heat exchanger is designed as a spiral pipe and transfers the heat directly in the boiler to the domestic hot water. The heat pump boiler is a prototype of the Nussbaum company. The heat pump boiler is located in the entrance area room no. 370 in a wall cabinet.
