The water consumption of gymnasiums is generally relatively large, 100 people should use at least 6 tons of water tanks to shower. Air-energy hot water gas is theoretically more energy-saving than electric water heaters, but only when conditions permit can the external environment temperature be efficient. Below 5 degrees, the efficiency is extremely poor, similar to that of electric refrigeration, even worse than that of electric refrigeration, because it still needs frosting, and the external water tank consumes a lot of power for heat preservation.

Therefore, the air can be suitable for the southern region, especially for valves with a temperature of about 20 degrees all the year round. There are many factors to consider when using air energy in winter in the north. If water consumption is high in summer, air can really save electricity by storing water.

No matter which one you choose, the design scheme is very important. An electric water heater is designed, which is more energy-saving than air.
