Hot water circulation mode under commercial air energy

1. Forced circulation system: hot water is circulated back to the hot water storage tank through a water pump or equipment to ensure the temperature and flow of hot water. This method is suitable for large commercial places, such as hotels, swimming pools and gymnasiums.

2. Gravity circulation system: Because commercial air energy water heaters are usually installed on roofs and other high places, natural gravity can be used to circulate hot water back to hot water storage tanks or use equipment. This method is suitable for smaller commercial places, such as office buildings, restaurants, small hotels and so on.
