Question: Outer housing fever and poor insulation effect


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.
