Thanks for all the thoughts on AquaHot's. We have the 600D so it has two heating elements. Guess we'll have to see how the unit works in cooler temps as the rig is new to us. Never had hydronic heating before and the only trip we've taken so far was to AZ and back so no really cool temps. Didn't need the heat pumps either, but did run the AquaHot some for heat and showers.
