According to different heating principles, water heaters can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic water heaters, air water heaters, heating water heaters, etc.

[0003] like Figure 1-Figure 2 As shown, the water heater includes an outer shell 100' and an inner tank 200' arranged in the outer shell 100' for storing hot water. There is a gap between the inner tank 200' and the outer shell 100', and the gap is used to fill the foam material for insulation and heat insulation. The water heater is usually fixed to the installation wall through a water heater mounting structure 300'. The water heater mounting structure 300' in the prior art includes an inner tank bracket 301', an insulating pad 302' and an outer wall hanger 303'. When assembling the water heater, firstly weld the inner tank bracket 301' on the inner tank 200', and install the insulating pad 302' on the inner tank bracket 301'; after the installation is completed, put the entire inner tank 200' into the outer shell 100' so that the threaded hole on the inner tank bracket 301' is directly opposite to the connecting hole on the outer shell 100'. Then, the external wall bracket 303' can be installed, and the bolt 400' is passed through the external wall bracket 303', the connection hole on the housing 100', and the insulating pad 302' in sequence, and then screwed into the threaded hole on the inner tank bracket 301', so as to realize the connection between the water heater and the water heater installation structure 300'.

At the position where the outer shell 100 is connected to the external wall bracket 1, one is to pay attention to heat preservation to reduce heat transfer; the second is to pay attention to insulation to prevent leakage at this location. The inner liner bracket 21 is usually made of metal, which is welded to the inner liner 200. By arranging the first insulating spacer 23 between the inner liner bracket 21 and the outer shell 100, it can play an insulating protection role, and the insulating material usually has a low heat transfer coefficient and can also play a certain insulation effect.
