[en] This work describes the methodology used to realize a performance analysis of two hybrid heat pumps (HHP) designed for space heating (SH) and domestic hot water (DHW) production for residential applications. The systems are installed in the same climatical region in the northern part of Belgium. The household composition of both facilities and heat requirements are different between them. Both installations count with sensors that allow to register the appliances gas consumption, electrical consumption, water flows and temperatures. Settings data are known but not monitored. The data collected is daily sent to the Cloud and is used to compute performance indicators. Two years of data are analyzed per site, allowing to quantify the effect of different variables over the system performance. The differences found are described and discussed.
