The most important thing about electric water heaters is whether they are safe or not, and physical stores can understand them more clearly. Now all manufacturers pay more attention to the safety technology, and they should pay attention to:

1, whether there is a PS three-pole flash (there must be a standard PS three-pole flash mark on the plug, otherwise it is all false);

2. Whether there is a built-in extended electricity-proof wall;

3, there is no water power protection function;

4. At present, some electric water heaters have realized intelligent human body detection power-off protection technology. As long as there is someone in the bathroom, the electric water heater will automatically power off. For example, A 16 of superman kitchen and bathroom.

Generally, an electric water heater contains the above three safety technologies at the same time, which is very safe.
