What are the reasons why the water heater can't catch fire

Gas water heater is not only convenient to use, but also cheap, which is deeply loved by the public. But it's also annoying to encounter the problem of not getting angry from time to time. Do you know the reasons why the water heater can't catch fire?

Causes and solutions of non ignition of water heater

  1. Power problem

Solution to ignition failure of gas water heater: check whether the indicator light of AC power plug is on, and eliminate the problem of power supply first

  2. Electric igniter failure

Solution to the problem that the water heater can't start: if one of the pulse igniter and the controller fails, the water heater can't start.

  3. Water gas linkage failure

The solution of the water heater can't catch fire: a. the tympanic membrane in the water gas linkage valve is aging or damaged, and the microswitch can't be pushed; b. The microswitch is broken.

  4. The air source switch is not opened or the air inlet filter screen is blocked

The solution to the problem that the water heater can't start: turn on the air source and clean the air inlet filter screen.

  5. The smoke pipe cannot exhaust normally

The solution of gas water heater can't catch fire: A. if the smoke pipe is blocked, clean the blockage of the smoke pipe; b. The smoke pipe is too long and not installed correctly.

Misunderstanding of gas water heater purchase

I. constant temperature. In fact, the current gas water heaters are constant temperature, and there are almost no non constant temperature. Even the forced exhaust gas water heater with hundreds of yuan is called "forced exhaust", but it also has a constant temperature device. The constant temperature device inside is a water gas linkage valve.

2. Real copper is oxygen free copper, which is also wrong. The water tank of real copper only shows that the main component is red copper, which is pure copper, but it has not been deoxidized, so the oxidation resistance is worse than that of oxygen free copper. Generally, when we open the shell of gas water heater, we can see that it is silver. In fact, the surface has been treated with tin dipping, which is a welding technology of real copper water tank, What we see in the oxygen free copper water tank is the true color of copper.

III. anti backflow treatment: almost all gas water heaters now have anti backflow treatment. Some are designed at the connection between the smoke pipe and the water heater, and some are inside the gas water heater. In fact, the reason is the same, that is, a movable flap. When the smoke is discharged outward, the flap opens and the flue is unobstructed, but when the external wind is too strong, in order to prevent the backflow of smoke, the flap will be closed under the action of wind, At the same time, when the air pressure switch of the gas water heater detects that the exhaust of the flue gas fan is blocked, it will automatically transmit the data to the single chip microcomputer, which will send a command to close the gas proportional valve.
