Since I'm new to hydronic heating, can anyone tell me what kind of battery draw I can expect from the Oasis unit compared to a propane furnace. I know the unit itself draws little power, but since there are several fans running throughout the coach, does it draw down the batteries more or less than a propane heater?

I found it hard to tell.

We went from a 4 battery coach with propane to a 8 battery all electric.

I do set the auto gen start to kick on at 11.7 volts and it never did start.

I doubt they all draw more than your old gas furnace did, no one has experience any problems on this forum.

Look at the main breaker/fuse on either AH or Oasis. On an AH 400D they are using a 20amp. Inside there is a "stir" pump, fuel pump (some units have an engine pre-heat pump) and each associated zone pump which also controls the heat exchanger fans for each zone, and of course the burner controls and ignition. The draw with all items running would be under 20amp on an AH 400D unless a coach manufacturer is using a seperate 12v feed for different exchanger fans rather than powering them from the hydronic unit itself.
