What’s Wrong With My Gas Water Heater?
I have a really serious problem with my home gas-typed water heater. my boiler’s flame just constantly burned out every 6 hours. I don’t see any water leaks around the boiler. I purposely looked at the shape and the color of the flame. All of the holes can ignite fire and the flame is all blue. I can successfully ignite the boiler every single time. What could be wrong with this boiler? Any advice or tips? Thanks in advanced….

I have a suspicion it may be a breached combustion chamber.
The theory…
When the unit is cold, all is fine. When it heats up, the crack expands enough to affect the pressure switch reading and unit shuts down.
The test…
Carbon monoxide detector. Call your gas supplier and ask for someone to come check it. They should come rather quickly if you tell them you suspect CO and why.
This is a potentially life threatening condition until you can confirm it isn’t the case.
I hope I’m wrong ’cause the fix will dent the coffers.
There are other possible causes, but I could only offer speculation without a schematic or at least the brand/model.
Best wishes.

Water heaters can be very fussy at times. Pending on the unit, you could have an assortment of problems. Dirty pilot will be one of the main contributors. Weak lazy pilot can be sucked out when the main burner comes on.
Thermocouple could be another issue. When they become weak over time, they can drop out with no warning. There is an adaptor that can be put between the gas valve and thermocouple to check both items with a meter. This process is called “checking dropout”. This test does not touch any live gas.
Another issue could be the gas valve may be either over firing or under firing. This can only be checked with a manometer. I would suggest this be done by a professional if you are not confident with working with live gas.
If the water heater is in a small tight room, there is also a possibility of lack of “combustion air” or “down draft”.
I need a make, model, and age to give you a more in-depth and accurate answer. I do work in the industry and believe me, the answer is always under the customers nose, they just don’t know it till some one points it out. A combustion air calculator can be found at my site. Hope this information helps

This is one you should call a professional on gas many problems probably the thermostat kicking the heater off but call a professional don’t work on gas or even guess at it TO DANGEROUS

Very easy fix! its the thermocouple, the device that keeps your pilot lit! Get a new one very cheap part under 10 dollars. 5 minute repair.

USA Not enough info. Is it the pilot flame that goes out? If yes, have there been any changes to the system? There could be a back draft problem.

It’s probably electrical — or a safety device that shuts it off. The ciculating pump may not be working right. Get proffesional help, or BOOM !!

Why do you have to relight the boiler? There should be a pilot light to light the burner. You may have a problem with the pilot light or the thermostat The burner should turn off when the water is hot enough at the Temp you have set it at. and if it is not relighting you may be better off to cal the gas man as not ever one should be messing with gas, the life you save may be yours

maybe the supply line is blocked
