Herman,
Thanks for the info.
This is the first time we've had this system in a motorhome and it works fine to heat the coach, but we still have a problem with enough domestic hot water. If we turn the electric on after we're parked we have plenty of hot water in a couple of hours. With the coach heating system off and just the diesel burner on with the electric to speed up the domestic water heating for extra shower capacity or washer we never get hot water. cool to warm. The diesel burner seems fine, no smoke, and a nice whine. Am still wondering if there is a priority switch I'm missing or a dirty valve. We recently ran into some bad water in a court in Arkansas that plugged filters and faucets. Just got back from Jacksonville, TX last week and had to winterize as we live in Eastern Montana. It is my understanding, to winterize the Aqua-Hot--- blow it out and pump RV antifreeze through it till it comes out the hot faucets. Correct?
Thanks,
Mike
