Buying points:
1, capacity selection
At present, the mainstream capacities of household electric water heaters are 40L, 50L, 60L and 80L. 40-liter and 50-liter electric water heaters can meet the needs of 2-3 consecutive baths. 60 -80 liters of electric water heater can meet the needs of 4-5 people for continuous bathing.
2. Selection of gasket
The inner container is one of the important parts of the water heater, which determines the service life of the water heater. Water heater liners are divided into stainless steel liners and enamel liners.
Stainless steel liner has the best performance and its service life can reach 15 years. However, it is difficult to weld, and the safety hidden danger of weld is great, so it is rare in the market. At present, the mainstream is enamel liner, which is composed of steel plate+adhesive layer+coating. The biggest difference between different brands is the coating, which determines the corrosion resistance, scale resistance and rust prevention ability. It is recommended to choose a patented liner.
