For the sake of safety, the cylindrical models of 60-liter and above storage electric water heaters generally need to be equipped with hooks, and the 60-liter hollow walls also need to be equipped with hooks; At present, there are 80 liters of ultra-thin hollow walls, so it is recommended to install hangers, and solid brick walls can be installed without hangers;

This kind of hanger is usually not included in the price of water heater, and customers need to buy it themselves, which is about 100 yuan.
