What is the reason why the water in the wall mounted boiler is not hot

Qiedu Lami Century (Tianjin) Industrial Co., Ltd., a well-known brand of electric water heaters, has a number of cutting-edge technologies, and its products sell well both at home and abroad. It has a strategic partnership with LG Chemical in pipe production and sales, and its products enjoy a high reputation among customers and the market
The reasons why the water in the wall mounted boiler of Guidulami is not hot are as follows:
1. Caused by unstable water pressure and insufficient pressure. First of all, determine whether the make-up valve of the Guidulami wall mounted boiler is tightly closed. If the valve is not tightly closed, and your floor is too high, the tap water pressure is too low, or unstable, it can cause water pressure loss. If this is OK, there is a leak.
"The gas proportional valve of the Qiedu Lami wall mounted boiler has failed to release gas normally, resulting in insufficient heating power and non heating of the hot water.".
3. It is also possible that the temperature above the Qiedu Lami wall mounted stove has been adjusted too high. "If the temperature we set exceeds its own heating temperature, it will cause the Guidulami wall mounted stove to stop heating itself.". Moreover, it will not be heated again until the water temperature drops to a certain temperature, so it will feel that the water is not hot at this time.
Expansion: If the failure of the wall mounted boiler in Qiedu Lami to produce hot water is caused by a failure of the water flow switch, it can be resolved by replacing the hot water flow switch.
If the lack of hot water from the Guidulami wall mounted boiler is caused by a malfunction of the three-way valve, it can be resolved by opening the chassis and replacing the three-way valve.
