To qualify for French Energy-saving Certificates (CEE), heat pump output must be between 40-80% of heat loss, as illustrated below: Hybrid heat pumps are subject to specific size requirements: heat pump output for an outdoor temperature of 0°C and a flow temperature of 50°C must be between 40-80% of the home’s heat loss at base temperature*. 2. I opt for a floorstanding or wallmounted model, depending on space requirements. 1. I opt for an outdoor unit covering a certain amount of heat loss within the home. 3.
