As the name implies, gas water heaters use gas as fuel to convert cold water into hot water. It has a fast heating speed and low cost. Therefore, consumers often consider gas water heaters when buying water heaters. Besides, the water heater is not used for a period of time, and the gas water heater is indispensable in winter or summer.

1. Appearance
The overall appearance of the energy rate gas water heater is simple and elegant, and it is installed on the kitchen wall without occupying space. This water heater also has an intelligent temperature control system, which intelligently remembers the user's usage habits. According to the temperature setting used last time, it automatically remembers various working parameters such as fan speed, gas volume, and firepower. The program reacts quickly and the water temperature rises quickly.
2. Packaging
This is the outer packaging of the product. We can see that this packaging is very rigorous, including all parts and components are fixed to prevent damage during transportation.
This energy rate gas water heater has many technological innovations. In the water volume control system, it integrates the detection of water volume, induction water volume, stable water volume, and water volume adjustment. The four-in-one water volume control system, through the unique shape memory alloy system of energy rate, will promptly enter the water The temperature and water flow are finely converted into current signals and passed to the smart chip to ensure that the water volume and air volume are perfectly coordinated.
The unmatched magnetic levitation moving coil gas proportional valve accurately controls the gas output according to the temperature set by the user. The dual-valve three-stage thermal power is automatically switched to make the outlet temperature perfectly constant.
3. Details
The new design of the heat exchange fins, the hole-shaped heat interception mechanism and the side bending of the fins increase the heat exchange area, so that the high-temperature flue gas and the water flowing through the waterway coil fully exchange heat, effectively improve the heating efficiency, and reach the national level 2 Energy efficiency standards.
The bottom is connected with cold water inlet and outlet and gas pipeline. The powerful DC stepless variable-speed imported fan supplies the air required for combustion in a reasonable ratio, and exhausts the exhaust gas generated by the combustion to the outside.
4. Core technology
The high-efficiency heat exchanger is a patent for energy-efficient water heater. It is made of thick phosphorous deoxidized copper material, which not only has good flexibility, but also can withstand high temperature, corrosion, fatigue and long service life. Coupled with the unmatched magnetic levitation moving coil gas proportional valve, the gas output is accurately controlled according to the temperature set by the user, so that the water temperature can be kept constant.
The dual-control water temperature setting is the design highlight of this product. It is controlled by a water volume sensor when entering water, and regulates the water volume within a certain range.
When the water is discharged, it is monitored by the water volume server, and the water flow is automatically adjusted according to the set water flow situation, which effectively increases the water output, which is more gas-saving and more energy-saving.
The four-in-one water flow control system senses the size of the water flow and detects the inlet water temperature. It is comparable to the aerospace technology's CPU-guided electrical control system. Based on the set outlet temperature, it calculates the amount of gas required for combustion and ensures complete combustion. The amount of air, the choice of a reasonable fan speed, and the firepower section required for combustion make the water temperature rise rapidly.
Waterproof backfill smoke exhaust pipe, independent waterproof backfill function, avoid backwater and prolong service life.
CPU electrical intelligent control system, full combustion, effectively increase the heating speed, accurate comparison of air and gas.
Evaluation summary: This energy-efficient gas water heater is not only simple and elegant in appearance, but also adopts advanced technology in innovation. It precisely controls the water temperature and water volume. The components of the product have been strictly controlled, the quality is excellent, and the service life is longer. In short, this is a gas water heater with good quality and high cost performance.
