1.1 Safety: When the air source heat pump water heater is heated, there is no electric heating in the water tank, the water and electricity are safely separated, and there is no hidden danger of electric leakage and electric shock. It is completely safe. When oil/gas boilers are used for heating, there are potential safety hazards such as gas leakage, poisoning and explosion.
1.2 Energy saving: The air source heat pump water heater has an energy efficiency as high as 400%-600%, and the oil/gas boiler energy efficiency is only 80-90%. The air source heat pump water heater can save more than 50% of the operating cost compared with the oil boiler.
1.3 Environmental protection: When the air source heat pump water heater is heated, the fuel used is a clean air source, which is an environmentally friendly product; when the boiler is heated, oil/gas is used, which will pollute the air.
1.4 Installation aspect: The air source heat pump water heater has a flexible installation position, which can be installed on the roof, basement, ground, etc.; when installing a boiler, a boiler room is required.
1.6 Approval for use: Air source heat pump water heaters are safe and environmentally friendly products, and the environmental protection bureau does not need to be approved for installation and use, but boilers do.
1.7 First investment and payback period: In terms of first investment, air source heat pump water heaters are more than boilers, but air source heat pump water heaters have a shorter payback period. Compared with the investment in boilers, the cost can be recovered in more than one year.
2.1 Safety: Both are safe products, but if the solar water heater is equipped with other heat sources (electricity, boiler), there will be safety hazards.
2.2 Energy-saving: Both are energy-saving products, but the operating cost of air source heat pump water heaters is about 1/4 less than that of solar water heaters.
2.3 Environmental protection: Both are environmentally friendly products.
2.4 Installation aspect: The air source heat pump water heater has many options for installation location, and it takes up a small space. It can be installed on the roof, basement, ground, and balcony. The solar water heater (engineering) must be installed in places where the sun is directly radiated, such as roofs, open spaces, etc., and it takes up a lot of space.
2.6 Maintenance: The air source heat pump water heater has low maintenance costs. The solar water heater needs to be cleaned after a period of use, otherwise the efficiency will drop quickly. Moreover, when a vacuum tube is broken, the entire project cannot be used, and the water in the entire water tank will be wasted. If it is not discovered in time, more will be wasted.
2.7 Natural disasters: When solar energy is installed on the roof, natural disasters such as typhoons should be considered.
2.8 In addition to the above, there are more advantages, as long as you use it, you can find out. Of course, there are also shortcomings, which should be considered comprehensively. Generally speaking, air source heat pump water heaters are more competitive in application and promotion than solar water heaters. Otherwise, there have no air source heat pump water heaters, the fourth generation of water heaters after gas water heaters, electric water heaters, and solar water heaters.
