Abstract: A method and retrofit system hot water or cold water consumption profiling to obtain electrical flexibility data of hot or cold thermal storage vessels driven by heat pump or a heat exchanger e.g. driven by electricity, such as electrical boilers with resistance heaters or driven by a heat pump or heat exchanger e.g. driven by electricity. In particular the determination of flexibility of thermal storage vessels such as DHW buffers or DCW buffers, e.g. for use in stabilisation of the electricity grid.

Abstract: A demand response adaptor is provided such that, depending on the device connected to the demand response adapter, the demand response control system can be provided with the second constraints corresponding to the device connected to the demand response adapter, wherein the demand response control system comprises software components for making the decision based on the first constraints, the second constraints and the third constraints, wherein the controller comprises software components for detecting the start of a program by analyzing the amount of electrical power used by the device in function of time detected by the sensor and wherein the controller of the adaptor comprises software components for switching the relay to the nonconductive state when the start of the program is detected until, based on the decision of the demand response control system, the controller switches the relay switch to the conductive state.

Abstract: A method for buffering thermal energy comprises a thermal buffering medium contained by a thermal energy buffer. The volume of the thermal buffering medium is subdivided in one or more parts such that the different parts of the volume of the thermal buffering medium together form the total thermal buffering medium. The thermal energy buffer comprises a temperature sensor for each part. A controller has at least one signal representing at least one thermal energy value related to the thermal energy buffer. The thermal energy values comprise a predetermined minimum amount of thermal energy present in the thermal energy buffer. The controller controls a heater such that the amount of thermal energy present in the thermal energy buffer is higher than or equals the predetermined minimum amount of energy present in the thermal energy buffer.
