Question: Outer housing fever and poor insulation effect

Answer:

1.  As the wall hanging plate tightly attached to the outer housing is connected with the inner cylinder too, the inner cylinder will transmit a small amount of heat to produce a certain temperature on the surface. It is a normal heat transmission.

2.  Normally the higher the water temperature, the longer the preservation time. Haier water heater have maximum temperature of 75 ℃. In accordance with experience, an average decrease of 2 ℃ effects normal heat preservation.

3.  Inspect hot water tubing for water cross flow from external lines (multiple supply), or hot water can not be stored because there is a leak on user home's water pipe. Close all water-using valve to find out if the water gauge is running to pass figures.
