Air source heat pump water heater VS electric water heater

Have you believe, this water heater can than the electric water heater save electricity 75%

Speaking of electric water heater, many users impression of it is: fast heating, but power consumption is too big. 

Electric water heater is the earliest water heater products, because of the water storage, so can’t out-of-the-box like gas water heater. Need to heating in advance. There are statistics show that an adult to complete a bath, consume 50L hot water. To get 50L hot water, and water heater have to get so much heat. And electric water heater is put into the form of electricity by electric heating tube, how much to produce heat, how much electricity consumption. The whole family to take a bath every day, every day so many kilowatts machine start, natural high electricity bills.

But recently there is a call of air source heat pump water heater products more fire, a lot of friends to get it compare with electric water heater. Say it than the electric water heater and energy saving, water tank capacity also seems to be a little more. Air source heat pump water heater is heat from the air. Cost of electricity is not used to generate heat, but handling hot. So the COP in the air source heat pump water heater, can be understood as “ handing ability and the water heater of heat pump uses the ratio of electricity.” This heating method, as long as the ambient temperature above 20℃, heat energy in the air, 4.0 the COP is not impossible.

 

Air source heat pump water heater to every moment of the day all the year round with the COP of 4.0 is impossible. Spring, summer, autumn and winter, the temperature in different seasons, have high have low. The temperature below 20℃is often the case. Accroding to the data shows that the air temperature around 10℃, the heater heating EER COP is 3.0 or so. When the temperature 0 ℃, and the air source heat pump water heater air conditioning can effect comparing the COP will reduce to 2.0 ~ 3.0.Once in the face of minus 10 ℃ ultra-low temperature environment, ordinary air source heat pump water heater air conditioning can effect comparing is likely to fall to 2.0 below.

 

We can also learn from the data, although the heating efficiency of air source heat pump water heater has been decreases as the temperature, but its heating efficiency is always higher than that of electric water heater, relative to electric water heater always have the advantage of energy saving.
