Pneumatic water heaters, also known as "air source heat pump water heaters", have a working principle very similar to that of air conditioners. They use a small amount of electric energy to drive the compressor to operate. Absorb a large amount of heat energy from the air; the gaseous working fluid is compressed by the compressor into a high-temperature, high-pressure liquid, and then enters the condenser to release heat to heat the water... Such continuous heating cycle can heat the water to 50° C~65°C.
Greatly reduce the cost of electric heating and hot water and save electricity bills
