SOURCE: Rinnai gas heater loud noise on ignition

It may be, Rinnai suggests a maximum length of about 13 equivalent feet of venting including elbows. Add 6 feet for every 90 degree elbow. If the vent is longer than this it is taxing the combustion fan motor and it will start giving you error codes and will not ignite. Remove the trim panel from behind the heater and find the flexable air intake pipe. Temporally remove it from a fitting and test the unit a few times to see if the unit starts quieter. This procedure will be taking room air into the heater for combustion and circumventing the direct vent feature of the heater, not a fix. Have you had the gas pressure tested? It gould be that! You may wish to consider relocating the heater and fire your installation contractor for putting you in this predicament, not Rinnai.

SOURCE: Loud Knocking

If the noise is not coming from the fan as Buffalo suggests, it is most likely the expansion and contraction of the heat exchanger. The old school way to lessen the noise of expansion is to bank the combustion chamber with a hammer. I don't recommend it today because the metal is so thin (thus all the noise) and you may damage it. You will get used to it and the noise may soften the more it is used. You will never get it to stop.

SOURCE: brivis ducted heater making a banging noise every

The heating system has a number of burners which must ignite as soon as the heater starts. When one or more burners does not fully or partially start properly, unburnt gas fed to that burner accumulates in a small pocket until is is eventually ignited causing a small explosion. This condition is caused by restricted/blocked burner jets. The gas jets are small and easily fouled by spider nests or other items sucked into the system. You will need to have the heater serviced by a qualified gas plumber.

Question, is this bang a metal sound or like a small poof of a gas burner? If it is a metal "bong", it is the heat exchanger expanding. You could hit the combustion chamber with a hammer causing a dent (really) and it may take the noise away. If it is a "poof", it should be looked at by a technician.

Adjust resonance screw makes loud noise on start up

I'm not sure what you mean "adjust resonance screw". I'm going to guess the adjustment screw your talking about is under at screw cover and is the appliance regulator screw. It adjust the gas input to your burners. Too low pressure is caused by backing the screw off and can result in delayed ignition or a "loud noise". It's really a small explosion caused by built up gas and damage your heater. Too high of pressure is caused by turning the screw in too far and can over-fire the heater which is also dangerous. I'm assuming you burn natural gas because with propane the appliance regulator is wide open. Your gas company may come and use a manometer to set the manifold pressure to factory settings (3.5 to 4.0 W.C.) for you. Otherwise, turn the screw back in until the ignition is not delayed and the loud noise is replaced by a nice quick ignition. Good luck.

My water heater have countinous loud sound?

There are several different things the sound could be. If it is a popping noise it could be from the sediment inside the water heater as it is heating. It could also be noise(bang) from the water pipes having excessive pressure. If the water heater is gas it could be the noise from the burner when in operation or gas regulator vibration. Need a better description of the noise to be more helpful.

Loud noises, shaking, visible white powder in chlorinator

Stop using the heater immediately. You are boiling the water inside and this can lead to a dangerous situation if a limit switch fails to act in time.

You will likely find the diverter in the inlet side of the heater is broken. You are looking for a stainless steel plate in the water path. If you can move it by hand, it is broke. It is not replaceable and requires a new heat exchanger assembly to repair it.
