Carl I'll tell you a story we really don't need a aqua hot in our coach we have inverter heat pumps and one good for 15 degrees plus for a standby a diesel air heater like in truck cabs the only reason we use the aquahot is for hot water and preheat the engine so the 120v element is all we use. I installed a flat plate heat exchanger along with a small diesel water heater like used on truck engines to make a on demand type hot water heater and in doing all this I used plastic fittings to experiment with different configurations and found what worked the best and left for Orange Beach Alabama for the winter ignoring to replace those plastic fittings with brass, the second night we pulled into a campground and I was happy that nothing blew up on our third journey in the coach but when I walked by the AH door smelled antifreeze and upon opening the door found every single one of those plastic fitting has mutated into odd looking creatures. I of course went to lowes and bought all the 3/4" brass fittings and replaced all of them I'm certain I was just a few minutes from a roadside disaster.
