Abstract (en)
A system for providing domestic hot water and a method using the system is provided. The system comprises a heat pump, a mains water supply, a heat exchanger establishing a thermal connection between a fluid line exiting the mains water supply and a fluid line exiting the heat pump, a thermal energy storage device connected to the heat pump, and a controller having different operation modes and being configured to select between them and control the heat pump based on a selected operation mode. In a first operation mode, thermal energy is provided from the heat pump to the thermal energy storage device, but not to the heat exchanger, whereas in a second operation mode, thermal energy is provided from the heat pump to the heat exchanger. The configuration of the controller to switch to the second operation mode allows the system and method to provide domestic hot water continuously, i.e. without downtimes.
