Les,

So glad to hear you are in business again with your Aqua-Hot and did not have to replace the tank.

There are a couple things you say in your post that I don't quite agree with and you might want to check on again.

First, the diesel should not have to be turned on for the electric elements to heat. You will have to have 220VAC available for the high wattage one to function. The diesel burner ( Webasto ) and the electric should be able to work completely independent, or together. It is the high wattage element that operates on 220VAC that makes the Aqua-Hot we have in our Newells so much more capable of meeting the needs of the coach without assistance from the diesel burner. The downside, is the big element pulls a lot of current and normal 50A service will not support it and the air conditioners at the same time. That is why Newell installed an interlock on many coaches that turns off the air conditioners if you turn on the electric for Aqua-Hot.

I also believe, just from what I have read, that the tubing used in the tank is copper, not brass.

Take care and enjoy your heat and hot water. Russ
