Simple selection judgment method
1, depending on the appearance (fineness of workmanship: treatment of water tank, bracket, screws and insulation materials)
2, look at the stent firmness (stent thickness), corrosion resistance (material), stability can also be weighed.
3. Thickness of water tank liner (weigh the water tank, which is a bit heavy for most people)
4, the color of the vacuum tube (single, all) whether there is color difference, whether consistent.
5. Price:100-1A pipe with a diameter of 58 in 20 yuan (including installation materials: upper and lower pipes, insulation materials, overflow pipes, heating wires, upper and lower connectors, indoor water supply system, a master valve, etc.). , excluding additional functions: electric heating, microcomputer, heat tracing, etc. ).
6. Capacity: Remove about 5 cm of thermal insulation material (see the position of the water outlet in the side section, and its lower end is the thickness from the thermal insulation layer to the bottom of the water tank) to calculate the volume of the water tank liner, which is the cylindrical volume, which is basically the water consumption available to users.
