Résumé

Heat pumps are expected to become the most widely used system for the production of domestic hot water (DHW) in dwellings in the coming years in Europe. The total decarbonisation of Europe's energy system by 2050 is currently producing changes in the sector, where traditional boiler companies have started to market heat pumps. This study analyses the performance of a compact heat pump for DHW production, which is simultaneously powered by PV panels (470 Wp) and the grid. The system (PV-HP) is designed to consume the energy produced by the PV panels in two ways: to drive the compressor or to power an electrical resistance within the water accumulator. The seasonal performance factor (SPF) of the analyzed system is around 9, which means that 1 kWh of grid electricity produces 9 kWh of thermal energy for DHW. The techno-economic analysis shows the benefits of this system when it is compared to a DHW heat pump without PV and a standard boiler.
