Recommended series: UT series, TE7 series, Casarte CD2 series, Commander LP1 series
 
Haier has the largest water heater production base in Asia, the world's largest share of electric water heaters, although the market performance of gas water heaters is not as strong as that of self-appliance water heaters, but in the "blue flame segmented air supply technology", "patented 21° bevel", "double security patented technology", "zero constant temperature technology" and other patented technologies are still not lacking in selling points. The unique Blue Flame technology ensures a full response to the combustion process, with CO emissions below 300 ppm and nitrogen oxides below 40 ppm, making it the first brand in the industry to meet this standard.
 
In addition to the Haier brand for the mid-end market, Haier gas water heaters also have high-end sub-brand Casarte and Internet sub-brand commander. Among them, the commander launched the LP1 series, which can be called the lowest price in the market of about 1000 yuan. Haier has launched the basic UT series, the TC series with 5 levels of variables, the TE7 series with water servo, the D5 series with WIFI remote alarm, and the M2 series with instant washing. The high-end sub-brand Casarte has launched the CD2 series, which can catalyze CO exhaust. Haier's products are all strong exhaust gas water heaters, which are relatively monotonous in type, but they are subdivided into functions and still have rich room for selection.
 
If you want to be simple and practical, the basic UT series has an eye-catching performance, with good performance in terms of constant temperature, energy saving and safety. The UT series is available in 10L, 12L, 13L, and 16L. The correct unit of water output should be liters per minute (L/min), which represents how many liters of water can be raised by 25°C per minute. If you simply supply a toilet shower, 10 L/min of water is enough for domestic use. Families with low temperatures or a combined kitchen and bathroom can choose 12-13L/min water output. Households with more than two bathrooms or with a bathtub need at least 16 L/min of water output. In addition, the UT series is equipped with a smart freeze protection function as standard, which is necessary for homes with room temperatures below zero in winter. The price of UT series 12 liters is about 1100 yuan.
 
If you have a good budget, you can enjoy a more detailed hot water experience by choosing the flagship TE7 series in one step, with fast constant temperature, high-rise wind resistance, triple bacteriostatic and other functional configurations, and the price of 13 liters of water output is about 2500 yuan. The product is equipped with a water volume server, which can ensure that the water fluctuation does not exceed 3°C after the water is turned off and re-opened in the middle of the process, which is far lower than the 18°C fluctuation of the national standard.
 
Casarte's CD2 series products have self-cleaning combustion technology, which applies platinum and palladium catalytic technology in aerospace to low-temperature catalysis, and expands the catalytic area to 5,000 square meters through the three-dimensional honeycomb design that actively eliminates carbon monoxide, fully eliminates incomplete combustion of CO, and purifies exhaust gas. Haier's first technology removes 98% of carbon monoxide from exhaust gases, treating the symptoms and root causes, and no other brand has launched a similar function.
 
Haier gas water heater after-sales guarantee is also a major advantage, most models promise 6 years of repair, more than 1700 yuan of some high-end models warranty period is up to 8 years, is the top in the industry. During Haier's warranty period, workers are exempt from door-to-door maintenance fees and parts costs, and the after-sales protection is far better than that of foreign brands. Haier's low-end products are anti-freeze and windproof, low practical price, good comprehensive cost performance and after-sales service, Haier's strong exhaust water heater is a very reliable choice.
