1. From investment:
If the same water supply effect is achieved, the funds invested in the heat pump water heater unit are less than the conventional solar products, and the economic energy can be used to make hot water storage when the electricity consumption is low.
2. From the use of:
Conventional solar products are obviously affected by the weather. They cannot work on rainy days, snowy days and nights, but the heat pump hot water units can work as usual, no matter cloudy, rainy, snowy, sunny or sunny, providing hot water all day.
3. From the aspect of operating cost:
The conventional solar energy in the sun, almost zero cost operation, but rely on the auxiliary system in rainy or snowy night work only, statistics show that in normal use, the conventional solar assisted system throughout the year power consumption is higher than the total power consumption of heat pump units.
4. Other functional aspects:
The use of heat pump units will not be limited by the place, can be placed anywhere, but a very small space, while the conventional solar heating to achieve the same effect would occupy a large space, must also be arranged; the heat pump unit can produce air-conditioners in the hot water system at the same time, available in addition to dampness, cooling and air filtration and other auxiliary functions.
The principle of "new energy heat pump water heater heat pump is a kind of low energy can be obtained from the nature of the air, water or soil, through the heat pump power output, high energy equipment, is a kind of energy-saving and environmental protection, clean heating refrigeration and hot water equipment, the world is the focus of new energy technology.
How to understand the heat pump: a simple example of the car consumption a few liters of gasoline can put several tons of goods from one place to another, heat pump can absorb heat from the air, groundwater in nature after heat pump handling (electric power driven heat pump), can be used to obtain high heat production and life.
Air energy heat pump hot water equipment in the air to absorb the temperature of the heat in the air, after compressor compression, converted into high temperature heat, heating water temperature. The air source heat pump hot water equipment has the characteristics of high efficiency and energy saving, its energy saving effect is 4 times of the electric hot water equipment, 3 times of that of the gas hot water equipment, and 2 times of that of the solar hot water equipment.
