Question Aqua Hot Storage Question

We just purchased a 2009 American Allegiance 42G with an Aqua Hot.

We plan on using the coach on and off throughout the winter, so really don't want to winterize it.

We have a storage location when we are not using it that provides 15Amp shore power mainly for the refrigerator.

So here is the question(s).
- Do we just keep the furnace on and the AH on electric? Is that enough to heat the coach to prevent freezing? And if so, is 15Amp enough to run it?
- Or should we keep the Diesel burner on instead or in addition to the electric? How much Diesel will we use while parked?

Thanks for the help.

You don't say which AH you have. One 110V, two 110V? A single will keep the MH warm to around 50F outside temp. You may also overload the 15A if heater and refer cycle at the same time. You shouldn't run the diesel heater in an enclosed area or is the storage outside? If I remember correctly the burner uses 1/2 gallon per hour of operation.

Thanks. Outside storage with a 15Amp circuit. Single AH system.

I guess I need to test how much power it uses. I'd rather just run off of the available 15Amps if possible since it doesn't cost me anything. As opposed to using diesel.

You can keep the diesel burner on all the time if you want to. It will only light off if the demand for heat or hot water exceeds the electric element's ability to provide it. The burner uses .4 GPH when running. My coach is in covered storage with standard house power. I place mulitiply trouble lights with 60w bulbs every place I want to keep from freezing, such as W/D, AH, water pump, back of the refer, etc. My power is very reliable, so I do not normally turn on the AH. The one time I have turned on the burner when in storage was when the temps were under 10 and it was very windy. I also turned on the gen auto start feature so if the power went out and the batteries ran down, the gen would come on and charge them.
