I have a BOSH tankless water heater at a camp. The water pressure is only 17 PSI as it is gravity fed from a 1200 water tank. How can I improve water pressure effectively ? Thanks Steeve

Pressure from a gravity system can only come from the height of the water tank above the height of the inlet to the heater. This difference is called "head". To get more pressure you need a greater head. You will need to raise the tank a minimum of 3'. Note: you could test the pressure using a hose, head is based on vertical height of water, and has nothing to do with volume of water.

New Rheem Fury Guardian System 50 gal water heater model 42V50-40F. Loud low humming or drone sound when in operation. What can this be?

Is the noise when the water is running or when the burner is running???

If it is just the water then the noise often is the flow checks inside the tubes going to and from the heater...

If it is the burner, then the noise could be the gas going through the gas valve...a bit of moisture or dirt can sometimes cause noises...usulally will correct its self after a bit of worry...

poping crackling sounds and such are common with mineral builsup in the bottom of the heater....
Flush the heater and get the dirt out....

sizzling noises sometimes happen from condensation dripping onto the burner....gain not a problem...

sometimes the gas properties will cause the gas to make noises when going through the gas orifice into the burner... usually this is air or a LP air mixture known as "citigas" that will burn like natural gas but really isn't and it will make noises such as your are describing...again no problem...

Ultimately the noise you hear is not a problem but can be irritaing if the heater is where you can hear it easily...

Feel free to comment back if you have any more questions...

Why does my water heater make crackling noises

The crackling noise is from build-up of sediment.
I forget exact reaction that causes the noise.
Water heaters exposed to hard water will create sediment inside the tank.

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.
