Air water heater, also known as "air source heat pump water heater", its working principle is very similar to the air conditioner. It absorbs heat from the air to heat water to 50°C~65°C. Compared to other kinds of water heaters, the biggest selling point of air water heaters is that they are energy-saving and environmentally friendly and safer.

Why air water heater "fire" up?

  • High price and high maintenance cost

Some residents of the home of the air water heater is the developer to send, with the experience will be very good. But if you want to buy their own, you will find that the price is higher than the gas water heater or electric water heater.

They are commonly sold for 5,000 to 6,000 dollars, and even 7,000 to 8,000 dollars. For the average family, the purchase of such an expensive product is undoubtedly a lot of money.

Apart from the cost of the product itself, the installation and maintenance costs are relatively higher. The working principle of the air water heater is more complex, so you need professionals to install and debugging, which also increases the cost and time of installation, installation of a time to several hundred. If the machine does not break down during the period is good, otherwise the cost of maintenance is not cheap, and sometimes even maintenance costs can buy a new electric water heater.

Our house just moved in half a year when it broke down once, after-sales came over to check and said that something in the tank was broken and had to be replaced, because the air water heater hadn't been bought for long, so it was a free replacement. However, I was charged 500 yuan for shipping and handling, and after a long negotiation and a call to the after-sales service to complain, I was finally charged 100 yuan.

Of course, this is beside the point. Due to the complexity of the working principle and structure of the air water heater, it is inevitable that various problems, such as water leakage, poor heating effect, etc., may occur during long-term use. In addition to the product cost and installation cost, the storage tank of the air water heater has to be cleaned once in 2-3 years. Together, these costs are generally not considered by the average family.

In the use of air water heater encountered the worst problem is slow burning, often need to wait for a long time waiting for hot water. Especially the lower the temperature, the worse the efficiency, the water temperature half a day are not up, cold winter places to choose the electric heat function, its consumption of electricity and ordinary electric water heaters will not be a big difference, can not account for a little advantage.

Some cold areas will also be frozen, resulting in only cold water not hot water. Otherwise you can imagine the cold days up only cold water to brush your teeth and wash your face, and come back at night with a kettle to boil several times hot water to go outside to pour the air valve "thawing" scene, the big wrong kind of proper.

Of course, although the air water heater has the above shortcomings, but it really will save more energy than electric water heaters and gas. And water and electricity do not contact, there is no risk of leakage, and do not have to worry about gas water heaters like carbon monoxide and other exhaust gas hazards.
