Which brand of natural gas water heater is good?

Wanhe, Sakura, Wan Jiale, Smith and Linnei.

1, Wanhe

With the brand positioning of "gas appliance Expert", Wanhe produces gas appliance products such as gas water heaters, gas cookers, gas wall-hung boilers, gas barbecues, gas air conditioners and gas heaters, kitchen and bathroom appliances such as electric water heaters, disinfection cupboards and range hoods, as well as new energy products such as solar energy and heat pump water heaters and integrated hot water systems with energy sources such as air energy+gas, solar energy+gas and electric energy+gas.

The unique thermostatic chip of Sakura Quan Zhi digital thermostatic gas water heater can intelligently calculate various environmental parameters, so that the water heater is always in good condition and the water temperature remains stable. The energy-saving calculation system can automatically calculate various parameters in combustion and avoid the invalid loss of energy.

Dual-channel high-precision gas proportional valve, equipped with two gas cut-off solenoid valves, double protection, which can effectively prevent gas leakage and ensure user safety; The gas proportional valve synchronously and accurately supplies gas through the parameters such as water temperature, water flow, water pressure, air temperature and air pressure fed back to cpu by sensors, so that the water heater can realize rapid constant temperature.

At the same time, due to the synchronous change of air supply, combustion is the best ratio and the most sufficient state, which eliminates the invalid loss of energy and saves energy efficiently.

3. Wan Jiale?

Wan Jiale is the main drafting unit of the national standard of "Household Gas Water Heater" and the participating drafting unit of the national standard of "Household Gas Stove". At the same time, it also took the lead in compiling the industry standard of condensing household gas-fired rapid water heaters and participated in the formulation of 43 national, industry and local standards.

Among them, there are 22 national standards, 22 industrial standards 10, and 22 local standards 1 1, which has promoted the overall upgrading of national standards and the industrialization and standardization process in gas appliance, China, and is the cradle of engineers in gas appliance, China.

4. Mr. Smith

The newly-built A.O. Smith Global Engineering R&D Center has two central laboratories, equipped with cutting-edge computer processing and testing equipment, including a patented test bench, which can monitor the performance of water heaters and transmit high-speed broadband data so that engineers in China and the United States can enjoy the experimental data.

R&D center has the ability to cooperate with American R&D personnel to detect and analyze products 24 hours a day, which is a very important competitive advantage of A.O. Smith and can provide faster and more efficient response for water heater customers.

5. In the forest

There are 75 self-inspection procedures when the water heater in the forest is started to ensure trouble-free operation. The water temperature is too high to burn easily. The water heater in the forest is specially equipped with a 48-degree safety lock function. When adjusting the water temperature to above 48 degrees, you must first close the water valve and set the temperature before starting it to prevent accidental burns.

In-forest heating furnace adheres to the technical background of in-forest Group for more than 90 years, relies on the advanced equipment, technology and research and development capabilities of the Group, and has a unique ultra-wide automatic constant temperature regulation technology, which can accurately match the actual demand heat load and save more than 10% gas as low as possible.

Advanced microcomputer control combustion mode, uninterrupted heat preservation control, effectively prolong the life of the machine and save energy; Equipped with water quantity server, it can intelligently detect and adjust the water quantity, and provide comfortable and constant-temperature domestic hot water while enjoying comfortable heating.

Precautions for purchase:

1, antifreeze function is a factor to be considered, especially for northerners. Some fuselages have no anti-freezing function, which can easily cause the fuselages to freeze, and in severe cases, the whole machine will be damaged.

2. Pay attention to the preservation of these two things when purchasing, in case the water heater has problems and needs maintenance.

Usage rules:

Prevention of carbon monoxide poisoning: the gas water heater must be installed outside the bathroom, and the smoke exhaust pipe must be installed to ensure smooth smoke exhaust. Users who use artificial coal must entrust professionals to clean the burner regularly (every 3 months or half a year).

Prevent gas leakage: always check each gas connector, gas pipeline or hose for leakage with soapy water. Once the hose is found to have cracks, it must be replaced immediately. In case of gas leakage, close the gas valve immediately, open the doors and windows for ventilation, and disable the telephone and electrical appliances. Users who use liquefied petroleum gas are strictly forbidden to put cylinders upside down or horizontally.

In addition, pay attention to timely replacement of products that have exceeded their service life. Keep in mind three precautions and four rules for water heater leakage prevention in winter: the power supply must have a reliable grounding wire, and check the leakage protection switch regularly (weekly) to ensure its normal operation.

Waterproof case frost crack: gas water heaters in northern areas must be equipped with anti-freezing valves or windproof devices. When the outdoor temperature is lower than 0℃, the anti-freezing operation should be carried out according to the requirements of the instruction manual or the anti-freezing warning sticker of the fuselage.
