Hello everyone, I have a longvie water heater and even putting it to the maximum the water does not heat it properly, it comes out barely warm, recently I made a cleaning of the serpentine, the flame is too much and blue at the base and then yellow, what sometimes also after being on a square pilot I open the hot water tap, it makes like strange noises, like "tac" "tac" repeatedly it takes the water to come out and then it warms up normal, now it doesn't heat

Hi.

Independent of the serpentine, you must clean the burners and injectors and verify that the ventilation tube is not clogged. Apart from that which is related to the quality of the flame, check the water valve, verify that the drum is in good condition as well as the needle that is well lubricated. Tell us how the water pressure is and what type of gas you use.

The burners are cleaned today the ventilation tube is fine, the water pipe falls directly from the tank, what membrane do you mean?
the needle lubricates it well and also changes the diaphragm today, the water pressure is normal, and the gas I use is natural gas, in the kitchen and stove it goes perfectly and with the blue flame
Hi. exemm

In Chile, we call the diaphragm membrane .... Language tangles Well ... When the flame is of poor yellowish or reddish quality, it becomes dirty in the burners, injectors, serpentine or defective ventilation I would recommend that you concentrate on those points. Verify that apart from being clean the burners are not cracked or broken on their sides if they should be changed, since they absorb too much oxygen, generating yellow flame, which despite being large and bulky heats 50% less ... .........Regards.

Hello Raul, I thank you for answering, hehe I thought it was strange about the membrane, it did not sound like something to me from the water heater ... well, I just commented to you to disassemble the valve and lubricate and it is well it was not covered, it had a screw in the base that did not move it, do you have any idea what it is for? On the other hand, I wanted to disassemble the burners and clean them or see if I can change them, can you think of anything else?
regards
Hi, exemm.

That little screw is used to regulate the flow of water, it is usually regulated for winter and then for summer.
3 reasons to change the injectors: covered with tartar or rust residue; the injector was enlarged by being cleaned with a very large needle; Change of type of gas. If you see them clean and in good condition you should not change it.
Clean everything very well and tell us ........ Greetings.

Hello Raul!
finally after changing some bronze cañotpos, the emmbrana and cleaning the radiator well, now it works well, do you think it is convenient for me to change the complete shirt and the burners? before changing it? What I see also the water inlet pipe (I think) gets too hot, wouldn't the water outlet pipe have to heat up?

the valve (tormillo) that was telling you is at the base of the flame regulator where you put the heating in pilot or give more power
Hi, exemm.

If they are not perforated and rusty, it is not necessary to change the burners, with respect to the jacket, if no filtration is visible, green or white tartar, a good clean is enough. In relation to the heating of the pipe of antrada to the heater, the truth is not normal, verify that the flame of the heater is cut 100% (burners) no more than 3 seconds after cutting the water faucet, if not it is possible that there is a ploblem in the water or gas valve ... tell us.

Hello Raul
I have a little tartar on my shirt, which seems to me to send me a macana this time before when I cleaned it, to remove all traces of carbon or ollin, I washed it with a pressure washer, now it's like black, I think it must be gray, or by On the other hand I think that some very minimal fissure capable has in the serpentine ... the burners cut the flame well, when I close the tap it goes out immediately
SOLUTION ACCEPTED
Hi, exemm.

The color after the washing of the serpentine does not influence its operation and especially when it is black, with respect to the physical state of it, it can still last a little longer ...... greetings.

thank you very much raul for your help !!, I could solve it, the problem was that the radiator was all covered, it was not correct the combustion of air-gas that made, greetings
