The tested SWH system had about 20% of the impact of an electrical water heater and half that of a gas water heater. [51] Analysing their lower impact retrofit freeze-tolerant solar water heating system, Allen et al. (qv) reported a production CO 2 impact of 337 kg, which is around half the environmental impact reported in the Ardente et al ...
The operating conditions' optimization of this system is the main challenge, because there are two opposing trends of the performance of the two sub-systems: by way of example, decreasing the evaporation temperature of the working fluid increases the thermal efficiency of the solar panel but decreases the performance of the heat pump, and consequently the COP.
