Aqua hot diesel or electric

[Kjungles]

I have a “new to me” 2003 Monaco executive and when plugged into 50 amp will the aqua hot automatically switch to electric or does that have to be done by switching to it? So far plugged in when I turn it on it only runs off of diesel.

You should have a switch next to your aqua hot diesel switch that says hot water heater 110 V. That is 110 V for the aqua hot. At least that is how mine is.

Ok so if I’m plugged in and that switch has been on but no heat then I possibly have something to look into…maybe the element???

There should be a breaker on the element circuit. It is AC current and should be in one of the breaker panels. I would check that first to see if breaker switch is off before digging into AH element. The electric element will take some time to heat the boiler fluid, so be patient for 2 to 3 hours before you have hot water. Hope this helps.

The early Aqua Hot systems only have a single 1650 watt electric element.  If left on over night it will provide some amount of hot water depending on how cold the incoming water is.  

The electric element will not heat the coach in cold weather.  You will need to turn the Aqua Hot diesel burner on or use the heat pumps on the roof.  

If you are not paying for electric, then turn on the Aqua Hot electric and the diesel together.
