Traditional high temperature heat pump water heaters mostly produce hot water with refrigerant, which is highly stable, uneasy to produce chemical changes, and is nonhazardous to human body; that is why refrigerant is widely used. However, the refrigerant is one of the CFCs, which has already caused great influence to the environment due to long terms of use; this is why it has been replaced with other materials nowadays. Currently, Suntech Solar Technology has become the agent of CO2 Heat Pump Water Heater of Itomic, which produces hot water with natural CO2, and the highest temperature may reach 90°C. During its production, there is not any combustion and smoke; the power consumption is also less. That is why it ensures the safety through the discharge of CO2, and is a device with high efficiency; as well as a product that carries future trends for consumers.
