      *High energy efficient:<\/p>\n

      As the soil temperature is relatively stable, ground source heat pump systems heat transfer efficiency is very high.The power consumption is 40~60% less than central air conditioner and gas boiler.<\/p>\n

      * Environmentally friendly and clean.<\/p>\n

      Ground source heat pump system, no boiler, no combustion products. Very clean and low-carbon.<\/p>\n

      * Comfortable and low noise.<\/p>\n

      It is a water system, the temperature is steable and comfortable. Super low noise as it works without big fan motor blowing.<\/p>\n

      * Multifunction.<\/p>\n

      Heating, cooling and hot water in one solution, heat recovery function is also available. One unit can satisty most of the demands.<\/p>\n<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
