With the improvement of living standards, gas water heaters have become an indispensable household appliance for many families. However, the quality of gas water heaters on the market is uneven, and improper selection often brings a lot of inconvenience. The following will start from the bad experience brought by poor gas water heaters, and discuss the configuration that a high-quality gas water heater should have.
1. The bad experience brought by a poor gas water heater
1. Slow heating speed and long waiting time: Poor gas water heaters have low heating efficiency and cannot provide enough hot water in a short time, especially in the case of continuous use by multiple people, the waiting time for hot water will be greatly extended, affecting the convenience of life.
2. Unstable water temperature: Due to the poor temperature control technology, the water temperature of poor gas water heaters often fluctuates during use, which greatly reduces the comfort of bathing.
3. Large safety hazards: Poor gas water heaters may have defects in the design and manufacture, such as imperfect functions such as gas leakage alarm and smoke exhaust safety detection, which increase the potential safety hazards in the use process.
4. High noise: The design of the fan is unreasonable or the quality is not up to standard, resulting in high noise during operation, which affects the rest and sleep of family members.
5. High maintenance cost: Poor gas water heaters are often prone to failure due to quality problems and need frequent maintenance, which increases the cost of use.
Second, the necessary configuration of high-quality gas water heaters
1. Efficient heating system: A high-quality gas water heater should have an efficient combustion system and heat exchange system, which can quickly heat water in a short time to meet the needs of multiple people for continuous use. At the same time, it has high combustion efficiency, energy saving and environmental protection.
2. Precise temperature control technology: advanced temperature control technology, such as water volume server, water and air dual adjustment, etc., to ensure that the water temperature is constant, avoid the problem of hot and cold, and improve the bathing experience. In particular, the water volume server can actively adjust the amount of water entering and outgoing according to the instructions of the CPU, and keep the temperature of the water outlet constant.
3. Safety protection device: built-in gas leakage alarm, smoke exhaust safety detection and other safety protection devices to ensure safety during use. At the same time, the design of integrated closed and stable combustion chamber and lower fan is adopted to improve combustion efficiency and wind resistance, and further ensure the safety of use.
4. Low noise design: using silent technology, the noise of the fan is controlled at a low level when it is running at full load, which solves the problem of sharp noise and roughness, and provides a quiet use environment for the family.
5. Intelligent control function: support mobile phone APP control, smart speaker control and other intelligent operations, convenient for users to adjust the water temperature anytime and anywhere. At the same time, some high-end models also have a cloud customization function, which can customize the water temperature mode according to the needs of different groups of people or scenarios.
6. Durable material and structure: As the core component of the gas water heater, the heat exchanger should be made of materials with high temperature resistance and good corrosion resistance, such as oxygen-free copper, phosphorus deoxidized copper, etc. At the same time, the overall structural design is reasonable to avoid the corrosion and water leakage problems that are prone to occur in the internal multi-coil solder joint structure.
When choosing a high-quality gas water heater, you should pay attention to heating efficiency, temperature control technology, safety protection devices, noise control and intelligent control functions.
