Air source heat pump water heater compare to electric water heater to save money
Air source heat pump water heater created by heat pump suppliers recently more fire, more and more people began to pay attention to this trendy water heater. Which is the most discussed is the energy problem. Some people think that air source heat pump water heater save power, but not save money. But there sare some people who say that the air source heat pump water heater as a whole is to save money. The two sides of the word, who is right?
To discuss whether the water heater energy saving, mainly to see its heating design. Air source heat pump water heater does not need to burn gas as gas water heater, it is somewhat similar to "electric water heater and solar water heater complex." Air source heat pump water heater is the use of refrigerant to absorb the heat in the outside air, and then to drive the compressor to work, after a series of heat transfer process, resulting in hot water. Although the air source heat pump water heater itself is power, but it is only for power consumption for the compressor, rather than the energy into heat. Thermal energy is mainly from the air free access to, so the air source heat pump water heater heating efficiency than electric water heater.
Electric water heater heating efficiency is about 95%, while the air source heat pump water heater heating efficiency according to the temperature changes in the 250% to 400% fluctuations. The general temperature reached 20 ℃, air source heat pump water heater heating efficiency can reach 400%, if it is cold winter, air source heat pump water heater heating efficiency will be slightly decreased.
In theory, the air source heat pump water heater heating efficiency is 4 times the electric water heater, which is 75% energy saving than electric water heaters, electricity is also about a quarter of electric water heaters. So that the air source heat pump water heater energy saving, this view is right. But the province does not save money, which have to convert electricity into actual money to compare. According to the data show that if the daily supply of 200L hot water, hot water heated from 15 ℃to 55 ℃, air source heat pump water heater is less than 500 yuan a year, while the electric water heater needs more than 2,000 yuan. Daily electricity costs, air source heat pump water heater to a clear advantage to win.
In addition to electricity, the cost of the purchase of water heaters have to come in. A high-end electric water heater, priced at 2000 to 3,000 yuan. A high-end air source heat pump water heater, priced at 6000 ~ 7,000 yuan. On the initial investment, the electric water heater than the air source heat pump water heater cheap about 4,000 yuan, a huge advantage. But the water heater is generally used for many years, so we have to consider from the overall income.
An electric water heater, the service life only 6 to 8 years. Air source heat pump water heater, if usually properly maintained, the service life can generally reach more than 10 years. According to the theoretical value, the two-year electricity tariff gap can reach 1,500 yuan. However, due to different regions of the environment, in order to rigorous, here by a minimum of 1,000 yuan. Air source heat pump water heater use 4 years, the overall expenditure and electric water heater quite. The next few years, due to higher heating efficiency, so more power than electric water heaters.
