Four «smart control» heat pump heating systems have been tested and evaluated as a whole by detailed measurements in the laboratory with the Concise Cycle Test (CCT). The measurement focused on the capability of the tested systems to deal with solar power in excess to household needs and with different types of energy storage (thermal or electrochemical). Thereby, not only the performance of the tested systems but also the advantages and disadvantages of various key performance factors were analysed.
