B5-04 Reducing Backup Electricity Consumption of Solar Water Heater Using Heat Pump

Solar-assisted heat pump (ISAHP) and heat pump-assisted solar heater (HPAS) were developed in the present study in order to reduce the backup electricity consumption of solar water heater. Test results show that the electricity consumption per liter of hot water at 55oC is 0.021 kWh/L for ISAHP and less than 0.01 kWh/L for HPAS. This energy consumption is much less than conventional solar water heater.
