I use the "Crown" gas water heater. Now it's getting hotter and hotter, and Zhixia has adjusted, but the water temperature is still the same.

The maximum heating capacity of gas water heater is certain. The water overflow temperature is low, and the water overflow temperature is high.

Try to open the inlet water. If it has been adjusted to the maximum, it is likely to be a scale blockage problem. The following phenomenon is that the hot water outlet is much smaller than the cold water outlet.

The water surface temperature of the heat exchanger (also called water tank) of gas water heater is very high, and water will produce scale, and some scale will adhere to the heat exchange surface. With the accumulation of service time, the scale layer will become worse and worse, which will seriously affect the heat transfer, resulting in low outlet water temperature, but the shell temperature will rise rapidly; Another part of the scale will gradually form a blockage with the water flowing into the hot water pipeline, resulting in the problem that the outlet of the hot water faucet is obviously smaller than that of the cold water faucet.

Cold water is normal, but hot water is small. We should consider why there used to be more hot water, but now there is less. The reason is that the more scale deposits, the more pipes are blocked.

It is recommended to clean and remove scale immediately. You can buy a set of disassembly-free descaler for gas water heater online, and use it to inject descaling agent into the water heater and clean the inside of the water heater and hot water pipes. The operation is simple and convenient, and it can be cleaned regularly in the future, which can avoid the recurrence of this problem.
