How much the air to water heat pump power consumption? Mainly influenced by outdoor temperature.When the outdoor temperature is lower,the heating time is longer,the power consumption is more,and vice versa. 2.Is the use and operation of air source heat pump unit easy? It is very easy. The whole unit adopts automatic intelligent control system. The user only needs to turn on the power supply for the first time, and fully realize the automatic operation in the later use process. When the water temperature reaches the user's specified temperature, the system automatically starts up and runs when the water temperature is lower than the user's specified water temperature, so that hot water can be available 24 hours a day without waiting. 3.How much the air to water heat pump power consumption? Mainly influenced by outdoor temperature. When the outdoor temperature is lower,the heating time is longer,the power consumption is more,and vice versa. 4.what conditions can not be used? When the power cut off can be use a bucket of hot water for a while. And without water or the water pressure too low can not be use.
