personally recommended gas water heaters are: Fangtai gas water heater, Haier gas water heater, Wanhe gas water heater, Wan Jiale gas water heater and A.O. Smith gas water heater.
1. Fangtai gas water heater
The gas water heater introduced by Fangtai, the swimming magnetized water purification technology of Fangtai gas water heater, strongly purifies impurities such as rust and iron filings in water without changing the original chemical composition, and has an intelligent hot cruise system with built-in intelligent temperature sensing engine. When the temperature is lower than the set value, the cruise system is started, and the cold water left in the hot water pipe is transported back to the water heater and reheated to ensure that it can be turned on and heated immediately within 24 hours. ?
2. Haier gas water heater
Haier gas water heater adopts dual-gas security technology, which can monitor the concentrations of carbon monoxide and natural gas in the air in real time, and immediately give an audible and visual alarm and exhaust gas in case of leakage; And the first dual-water servo zero fluctuation constant temperature system in China, intelligent three-point temperature control and dual-water server combination attack, to achieve 3 seconds fast constant temperature; At the same time, the power carrier technology originated from the slimming plan of Yutu lunar rover can be used to transmit signals through the partition wall and solve the safety problem across space.
3. Wanhe gas water heater
Wanhe gas water heater adopts energy-gathering combustion technology. The products not only have manual temperature adjustment, but also intelligent bath and automatic constant temperature control. The built-in flow regulator is adopted for the low water pressure in some areas of China, which can boost the pressure, make the water flow more sufficient, and ensure the constant performance of water temperature.
4. Wan Jiale gas water heater
Wan Jiale gas water heater adopts fully enclosed blast combustion, and realizes stepless frequency conversion adjustment of air volume and air volume through high-speed calculation of the controller, thus realizing full-load stepless frequency conversion combustion. The intelligent wind-resistant system adopts fully enclosed combustion system and intelligent wind-resistant system, which improves the wind-resistant ability to above level 8, and consumers can use the water heater normally under level 8 gale.
5. A.O. Smith gas water heater
The products of A.O. Smith gas water heater have 15 machines in several series, such as carbon monoxide safety protection type, constant temperature type and 28L large elevation. A.O. Smith gas water heater has obtained many national patents, such as "patented carbon monoxide safety protection system", condensation energy-saving system and so on.
Precautions for choosing a gas water heater
1. Pay attention to the safety factor
Before buying a water heater, there is another trivial matter, that is, carefully ask the shopping guide what the safety protection function of the selected water heater is, whether it has the functions of preventing boiling and dry burning, whether the function locking is perfect, and whether there is a flameout protection device.
2. Whether there is anti-freezing function
Anti-freezing function is also a factor to be considered, especially for people in the north. Some airframes have no anti-freezing function, so it is easy to cause the fuselage to freeze, and in serious cases, the whole machine will be damaged.
