After Qianfeng water heater turned on the shower, the temperature was set at 35 degrees, but it was always above 46 degrees.

Common causes of water being too hot: low water pressure, low water flow, blocked water pipes and high air pressure.

Solution: change the water pipe to a certain caliber to increase the water flow; Regularly clean the filter screen of the water heater inlet pipe, keep the water flowing smoothly, reasonably adjust the water mixing valve, and install a decompression device on the gas pipeline.

Common causes of low water temperature: low gas pressure, blocked gas pipeline, incorrect water temperature adjustment, excessive pressure of tap water pipeline or excessive pipe diameter.

Solution: Check whether the gas pipeline is blocked. Connect a pipe from the gas meter to the air inlet of the water heater and connect it directly with the water heater. If the water heater can work normally, the pipe from the water meter to the inlet of the water heater is blocked. When checking, be sure to pay attention to the following parts of the household gas meter and pay attention to safety. Never move the pipe above the gas meter and gas valve. If the waterway fails, turn down the valve of the water inlet pipe and raise the set temperature of the water heater.
