Aqua hot noises

May 23, 2013, 12:05:59 am

I can hear my aqua hot motors running.  It seems there is a circulation pump and a blower of some kind?

Slight whining noises.  Is this normal?

Yes indeed, I can hear my unit running IF I turn off all noise makers such as TV, Radio & A/C including any air handlers.  Otherwise I need to open the compartment to hear it.
Maybe I am deaf, and your mileage may be different.

My Aqua-Hot is nearly silent when operating on electricity, unless a room (or basement) thermostat is calling for heat, in which case I can hear the circulation pump(s) and (of course) the heat exchanger blower(s) in the room(s). The Aqua-Hot does make noticeable (but not objectionable) sounds (both from the diesel burner motor and the exhaust) when the diesel burner is operating.

I have found that unless I stick my head out the bathroom window, I really do not hear the Aqua-hot unit. On occasion, during a real quite time, I can hear it inside. It is when I turn up the temperature during the cold months and hear nothing that I get real worried.

I have my unit serviced each year. Since this is like an oil burner in a house, so to speak, you need yearly service. I have had to once change the motor in the unit and the sensor for low fluid. I found making a jump wire that I could disconnect the wires from the low fuel sensor and used to by pass this sensor solved one issue. Naturally, this sensor failed at 11:00PM on a mid winter night with one foot of snow outside.

Thanks for everyone's info.  We were dry camped at the entrance to the Grand Canyon in a forest service camp last night and with no noises I could hear the blower come on and the circulation pump come on and the internal fans come on.  Very minimal noise actually.  Far background stuff.  Versus a normal Rv propane furnace its 1/10 the noise.  And the temperature fluctuations are much smaller.

Just the tiny whining noise when the motors are running.
