Abstract (en)

A system and for providing domestic hot water and/or space heating within a building is provided. The system, which can be used in the method, is characterized in that it comprises a first storage device containing a first phase change material, a first detector for determining the state of charge of the first storage device and a first phase change material heat exchanger suitable for exchanging heat between a refrigerant from a refrigeration circuit and the first phase change material. The system further comprises a second storage device containing a second phase change material, a second detector for determining the state of charge of the second storage device and a second phase change material heat exchanger suitable for exchanging heat between the second phase change material and water of a heat medium circuit. A controller is configured to control an operation of the system based on at least a state of charge of the first storage device and a state of charge of the second storage device.
