How is it that gas water heaters don't catch fire in hot weather and cold weather?

It is recommended to check the outlet of the hot water faucet. If it is small, it may be caused by insufficient water flow.

Cold water is normal, but hot water is small. We should consider why there is a large amount of hot water, but now the amount of hot water is small. The reason is that the scale accumulates more and more, blocking the pipeline, the water flow rate does not meet the conditions, and the water heater can't catch fire.

There are many reasons why gas water heaters are not easy to ignite. Any damage to water, gas and electricity will cause the water heater to fail to ignite. But now the quality of water heater parts is generally improved, so it is not so easy to break down. In fact, in many cases, the reason for their ignition failure is that the hot water pipeline is blocked due to waterway scaling, which leads to a large back pressure of waterway flow to a certain extent. The water-gas linkage device of the water heater will think that the hot water faucet has been closed and the gas path has been closed. Without gas, of course, it can't be lit. If the hot water faucet is fully opened recently, the hot water pressure is low, which is more likely. Now that the igniter is working normally, it is more certain.

It is recommended to clean and remove scale immediately. You can buy a set of disassembly-free descaling agent 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 the hot water pipe. The operation is simple and convenient, and it can be cleaned regularly in the future, which can avoid the recurrence of this problem.
