1. High-efficiency&energy-saving     
1) Air source heat pump uses heat energy from air(including heat recovery) and produces more heat energy, COP more than 4     
2) Energy saving more than 60%~80% compared to traditional heaters.     
2. Practical      
1) Air source heat pump provides for villa, apartment, high-floor residence, business restaurant, hotel and multi-floor living building in country and village.     
2) Heat pump is a replacement products of oil boiler,gas boiler, coal boiler, electricity and solar water heater etc.

3. Safety      
1) Separating the water from electricity or any other hazard material.     
2) No potential dangerous of any inflammable, gas poisoning, explosion, fire, electrical shock etc.     
4. Environment-friendly     
1) The heat from air and exhausting cooling air which is without any pollutions     
2) So we have no pollutions to any animal and heat pump also has effective influence of global warming
