Does air energy really save money?

Air energy water heaters are known for their energy efficiency, which is very high under the same environmental conditions. For example, if you have a 150-liter hot water tank at home, the daily consumption cost is: electric water heater needs 4.4 yuan, gas water heater needs 1.85 yuan, solar water heater needs 4.4 yuan (rainy day), while the air energy water heater needs 1.1 yuan. Visible air water heater costs only 25% of electric water heaters, gas water heaters 66%, than the actual utilization of electricity-assisted solar water heater energy efficiency is also higher than 20%, every day to save a little bit, long time is a small amount of money, in schools, hospitals, factories and other centralized hot water supply projects, air water heaters, the economic efficiency of the more clearly reflected. Because it has such a high energy efficiency ratio, so in the home, the air water heater in the hot water can also play a good role in saving money.
