As early as the end of the 19th century, the first water heater was produced in Germany, from industrial use to domestic water use, the whole process took more than 100 years. In 1979, China's first gas water heater was officially launched, and in the following decades, gas water heaters were constantly updated.
Early gas water heaters are relatively troublesome to install, and they are prone to dangers such as deflagration and gas leakage after a long period of use. So at that time, everyone bought the heat, the most concerned is the safety performance of the product, depending on whether it is a strong exhaust type, whether there is a carbon monoxide alarm device. Until the late eighties, big domestic brands such as Vanjiara began to introduce gas water heaters with flameout protection devices.
Later, with the continuous improvement of people's living standards, consumers' attention shifted to a more comfortable and high-quality bathing experience, and the focus of purchase at this time became the amount of water is large, the water temperature is unstable, the requirements are higher, and it depends on whether there is zero cold water function and so on.
In the past two years, people's demand for home life began to gradually develop in the direction of scene and high-end, gas water heaters must not only have a beautiful design, but also preferably have a small body, so as to better integrate into the installation environment of modern families.
However, the small size of gas water heaters, the general capacity is relatively small, unless the combustion rate of the water heater is increased to improve the thermal efficiency, but this is a challenge to technical capabilities and production costs, so there are really not many heat products on the market that can take into account both small volume and strong performance.
However, we recently reviewed a new gas water heater JSQ30-16A3J of Vanjiara, as the flagship model of the brand, this new product is not only particularly capable of functional configuration, the number of liters can also reach 16L, more importantly, its volume is particularly small, about 45% smaller than the traditional gas water heater.
Generally speaking, most gas water heaters are about 35 cm wide and 50 cm high. The height of this Vanjiara A3J is only 41 cm high and 29.6 cm wide, and the whole machine is about the size of an A3 printer paper from the front!
The appearance design is also amazing, the overall look is screwless integrated design, with pure white tempered glass panel, simple and generous, usually very clean. Even small apartments can be easily installed in the kitchen without obvious "protrusions", and the interior decoration design also complements the interior decoration design.
We studied it and found that this gas water heater has not made much effort in technology in order to grasp the small volume and strong performance at the same time.
For example, the heat exchanger of the general traditional gas water heater has a coil, this A3J original extreme fire micro-flame technology, cancel the radiation heat exchange section, the use of coilless heat exchange design, 4-stage small fire combustion, this is a big move, the minimum temperature rise control within 3 °C, the weather temperature difference can also achieve a constant temperature of the water. It also re-optimizes the premix runner design to improve the air-fuel mixing effect, which can reduce the flame height by 25%, thus effectively reducing the height of the product.
For example, A3J replaced the commonly used copper heat exchanger with a food-grade small stainless steel heat exchanger, which is more resistant to corrosion and scale, which can effectively reduce the risk of water leakage and extend the service life. Moreover, this stainless steel heat exchanger adopts flat tube surround heat exchange, compared with the traditional round tube and micro round tube, the shape of the flat tube can effectively increase the contact area, so that the convective heat transfer coefficient between the high temperature flue gas and the heat exchange tube is higher.
In addition, the water box connection on both sides replaces the traditional bent pipe connection method, which greatly reduces the installation width of the heat exchanger. Of course, this method is more difficult, and it also tests the manufacturer's production process, and generally only high-end machines of large brands will be used.
When we take a bath, stop the water and turn it on, the water temperature is easy to suddenly rise the problem, in fact, this reason is also very simple, we turn off the water, although the fire of the gas water heater is also turned off, but the water tank still maintains a high temperature, the residual temperature will increase the temperature in the water pipe, the national standard stipulates, this water temperature is controlled within 18 degrees Celsius is qualified. But for ordinary users, a temperature fluctuation of 18 degrees is enough to make people feel uncomfortable, so many gas water heaters will set up a constant temperature warehouse inside.
Vanjiale A3J designed an integrated stainless steel constant temperature chamber, which adopts a unique multi-cavity mixing structure, which is smaller than the circular constant temperature warehouse structure of ordinary gas water heaters, and the effect will not be discounted, which can realize the premixing of cold and hot water in advance to ensure the constant temperature output of hot water, even if it is turned off briefly during the bathing process and then opened, the water temperature can be effectively controlled, and the water temperature will not become significantly hot or cold, allowing users to experience the comfort of bathing without temperature difference.
In addition, residents of high-rise, large-area duplexes and villas often encounter the problem of low water pressure and low water output. This is mainly to see whether the water heater has no pressurization function, Vanjiale A3J uses water and gas double pressurization technology, through the effluent, heat double pressurization, not only increase the water output, but also ensure the stability of the outlet temperature, even in the low water pressure environment, can also provide surging hot water.
After we installed it, we experienced it, the water temperature is very stable, at the beginning it is hot water, and the water flow is also sufficient, this water output, I feel like I am standing under the waterfall to take a bath.
There are also some users who also have a demand for the speed of hot water from the water heater, after all, most people are already very tired from working during the day, and they definitely don't want to spend time waiting for hot water when they come back, they just want to take a quick hot bath. Vanjiale A3J is equipped with Oriental Constant Core 2.0 zero cold water, compared with the first generation of technology, the hot water head is larger, the circulating pipe is longer, no need to install a return pipe, can meet the hot water needs of the vast majority of household users, the faucet is turned on, the hot water gushes out, standing under the shower and waiting for hot water, cold shivering These pain points do not exist.
In addition to these core technologies, this Vanjiara A3J gas water heater is also equipped with AI pipeline adaptive technology, which can intelligently identify the water environment and pipeline length of the whole house, detect the distribution of cold and hot pipes in the whole house, and automatically identify the pipes that need to be heated, shortening the heating time while saving gas, making it more environmentally friendly.
It also supports WiFi intelligent control function, users can realize remote operation, appointment heating and other functions on the mobile phone, making bathing water more intelligent and convenient.
In addition, the quality of the domestic big brand Vanjiale can be assured, and the after-sales aspect is also very good, not only the product is used with confidence, the brand after-sales is also very guaranteed, whether it is a new house decoration or an old house renovation It is a recommended high-quality choice.
