2, air water heater, also known as "air source heat pump water heater" "cold air water heater" and so on." Air water heater" to the air in the low-temperature heat absorption, after the compressor compression into high-temperature heat energy to heat the water temperature. Air water heater has the characteristics of high efficiency and energy saving, manufacturing the same amount of hot water, than electricity-assisted solar water heater utilizing high energy efficiency. This new product overcomes the shortcomings of solar water heaters that rely on sunlight to extract heat and are inconvenient to install. Because the air water heater works through the medium of heat transfer, so it does not require electrical heating elements in direct contact with the water, to avoid the danger of leakage of electric water heaters, but also to prevent the gas water heater is likely to explode and the risk of poisoning, and more effective control of gas water heater exhaust emissions caused by air pollution.
3, air source heat pump water heater, as the name suggests, is the heat in the air through the refrigerant transported to the water, the traditional electric water heater and gas water heater is through the consumption of gas and electricity to obtain heat energy, while the air water heater is through the absorption of heat in the air to achieve the purpose of heating the water in the consumption of the same electricity can be absorbed in the case of the equivalent of three times the amount of electricity about the thermal energy to heat the water.
4, floor heating is short for radiant floor heating, English for Radiant Floor Heating, is the entire ground as a radiator, through the floor radiation layer of the heat medium, uniform heating of the entire ground, the use of the ground's own heat storage and heat upward radiation from the law of the bottom to the top of the conduction, to achieve the purpose of heating. From the heat medium is divided into two categories of water and electric floor heating, from the pavement structure is divided into wet floor heating and dry floor heating two kinds of dry floor heating does not need to be stone backfill (belong to the ultra-thin type); from the surface finish material is divided into floor type floor heating and floor tiles floor heating; from the function is divided into the ordinary floor heating and far-infrared floor heating.
