This paper describes the performance evaluation of boiler and heat pump hybrid hot water supply system. This system combines the CO2 heat pump water heater with the existing hot water boiler. This aims at reduction of consumption energy and CO2 emissions. As a result of carrying out the simulation of the four cases, it turned out that a hybrid system is energy saving most. CO2 emission is reducible about 35% by using a hybrid system as compared with hot water boiler.
