Multi heat source & multi functional air to wa

It is intergrated with solar collector, gas/fuel boiler and electrical heater to provide you a complete heating solution ( both for house heating and sanitary hot water heating ) It optimized the energy utilization of free energy ( solar energy ), green energy ( heat pump ), traditional energy ( gas / fuel boiler and electrical heater …) solar energy is free for everyone in the world, so it is the first heat source for heating system. This heating system will take full advantage of solar energy first, and if the free energy is not enough, then it will cycle on the heat pump to provide. On the condition that both solar energy and heat pump can not provide enough heat to your house and water ( in extreme cold condition ), then it will turn on the built-in electrical heater or gas / fuel boiler as back-up heating source to supply enough heat and keep a comfortable warm environment for you. Key features: l it combines a well-designed, high quality outdoor unit with an unique indoor unit to produce an advanced, high efficient, environmentally-friendly heating system. l Split type avoid water freezing problem outside of house in extreme condition. l Multi-heat source, optimization the energy utilization of solar energy, heat pump and traditional heat source. l Much bigger evaporatorto assure a good performance even in very, very cold conditions. l PLC controlling system which enables us adjust the program according to customers’s needs. l Human interface with 5.4’ LCD real color touch screen displayer, you can input your logo, company information, pictures to the displayer. l Internet module is available. (optional ) it allow you to know the working state of heat pump wherever you are n the world. Much easier for service man to know what happened on the heat pump l Built-in electrical heater to provide you back-up heating source when you do not have solar collector and boiler. l 200L built-in water storage tank for sanitary hot water
