What is the most energy-saving and environmentally friendly water heater currently? Used for bathing and hotels.

It is recommended to use: air energy heat pump or dual-source air energy heat pump (heat recovery)

Advantages of air energy: absorb energy in the air to heat water, equivalent to 4 times of electric hot water times capacity.

Advantages of dual-source air energy: The heat discharged by the air conditioner is converted into water heating, making full use of electrical energy. Hot water is equivalent to 6 times of electric heating.

Unique features:

Heat energy comes from a wide range of sources, including sunlight, rain and air. No matter it is day or night; no matter it is sunny or cloudy, windy, rainy or snowy, it can work as usual. It is not affected by the climate and can work as usual all year round;

Can be placed anywhere, so that It will not affect the appearance of the building, takes up very little space, does not require direct sunlight, and is very easy to install. It can be placed in the open air, or placed in an inconspicuous corner or basement, and can realize unmanned operation and fully automatic control of temperature and water supply;

The scope of application is very wide: it can be used in hotels, restaurants, factories , schools, hospitals, saunas, beauty salons, swimming pools, greenhouses, farms, laundries, homes, etc. It can be used individually or in a centralized manner. Different product series and installation designs can be selected for different heating requirements. At the same time, you can also get free air conditioning to meet your requirements from any angle;

Excellent CFC-free insulation, with only 2% heat loss, can maintain water temperature for a longer time, and the thermal efficiency is indeed twice that of other conventional solar products . The refrigerant does not contain Freon and does not discharge any waste gas or waste water. It is absolutely environmentally friendly. There is no gas or electric drive in the water tank, so it is absolutely safe.

The energy saving effect is obvious. Compared with using fuel, gas, electricity, coal, etc., it can save at least 75% of operating costs, allowing you to easily recover costs.
