Evaluation items: product appearance, packaging evaluation, detail evaluation and technical evaluation.
First, the product appearance
Energy rate GQ- 1380AFE gas water heater is simple and generous in overall appearance, and does not occupy space when installed on the kitchen wall. This water heater can intelligently control the temperature and remember the user's usage habits. According to the last use temperature, it can automatically remember the working parameters such as fan speed, air volume and firepower. When it is used again, the program set by the microcomputer intelligent chip can respond quickly and raise the water temperature quickly.
Second, the packaging evaluation
The above picture shows the unpacking and packaging of GQ- 1380AFE gas water heater unified by energy efficiency company. Please don't open the package at will when there is no energy efficiency designated person to install it. If the energy efficiency installer opens the package, the energy efficiency group will bear any internal problems.
Third, the detailed evaluation.
GQ- 1380AFE gas water heater is a newly designed heat exchange fin. The heat exchange area is increased by the hole thermal cutting mechanism and the fin lateral bending, so that the high-temperature flue gas can fully exchange heat with the water flowing through the waterway coil, effectively improving the heating efficiency and reaching the national second-class energy efficiency standard.
The bottom of GQ- 1380AFE gas water heater is cold water inlet and outlet, which is connected with gas pipeline. Strong DC stepless variable speed imported fan and reasonable proportion supply the air needed for combustion, and all the waste gas produced by final combustion is discharged to the outside.
Fourth, technology assessment.
High-efficiency heat exchanger is the patent of high-efficiency energy-saving water heater. Made of thickened phosphorus deoxidized copper, it has good flexibility, high temperature resistance, corrosion resistance, fatigue resistance and long service life. Coupled with the unparalleled magnetic suspension moving coil gas proportional valve, the gas output is accurately controlled according to the temperature set by users, so that the water temperature is constant.
Double-control water temperature setting is the design highlight of this product. When water enters, it is controlled by a water sensor, and the water quantity can be adjusted within a certain range.
When the water comes out, the water server monitor automatically adjusts the water inflow according to the set water outflow condition, which effectively improves the water outflow and saves gas and energy.
Four-in-one water control system, sensing water flow and detecting inlet water temperature, is comparable to the electronic control system guided by CPU of aerospace technology. According to the set water temperature, it calculates the amount of gas needed for combustion and the amount of air needed to ensure complete combustion, and selects reasonable fan speed and fire section needed for combustion to make the water temperature rise rapidly.
Waterproof backflow smoke exhaust pipe, independent waterproof backflow function, avoiding backwater and prolonging service life.
The CPU electrical intelligent control system can fully burn, effectively improve the heating speed and accurately compare air and gas.
Evaluation summary:
This efficient and energy-saving gas water heater is not only simple and elegant in appearance, but also adopts advanced technology in innovation to accurately control water temperature and water quantity. The parts of the product are strictly controlled, with excellent quality and longer service life. In a word, this is a gas water heater with good quality and high cost performance.
