First, what is the best water heater


1. Air energy water heater, the structure is complex, the price is high, the maintenance is not more, the installation is troublesome, the space is large, the ambient temperature must be above 0 degrees; currently the water heater with high energy efficiency ratio.


2, storage type electric water heater, occupying a large space, low energy efficiency (electricity); not affected by environmental temperature, cheap, long life.


3, fast-heating water heater, short life, high failure rate, high price, high load capacity of the circuit; more energy-saving than traditional water heaters, not affected by environmental temperature, occupying a small space.


4, solar water heaters, have requirements for sunshine and ambient temperature, high prices, inconvenient to install, subject to floor restrictions; energy saving.


5, gas water heaters, the failure rate is slightly higher, installation is inconvenient; save money than electric water heaters, not affected by environmental temperature.

The water heater tank pressure rating is generally 0.75MPa (different models, different ratings). When the internal pressure of the overpressure protection device reaches the rated value, the safety valve should be automatically opened to relieve pressure to ensure safety. . The leakage protection device generally requires that the power supply be quickly cut off within 0.1 second when the leakage current reaches 15 mA. To purchase products with the Great Wall Safety Sign.

At present, there are many electric water heaters that are advertised as energy-saving in the market. So how do you see that the product festival is not energy-saving? In a word, it is “seeing the energy efficiency label”. Consumers are advised to choose an electric water heater with energy efficiency level 1 or energy efficiency level 2 as much as possible. Second, you should choose an electric water heater with more excellent energy-saving technologies. The amount of energy-saving technology is another major criterion for measuring the energy saving of electric water heaters.


The above article is a small series to introduce to you what is the best water heater, water heater purchase skills. I believe everyone knows everything after reading it. Buying tips can not only help us buy good products, but also help us save money and time. These buying techniques are everyday knowledge. Your reading is the motivation of Xiaobian.
