The water heater was plumbed between the heat exchanger and the injection elbow
, and the sink water was damned hot when the engine was running
If you think about it, if the water heater exchanger rots out, I'd rather have saltwater in my plumbing
How would you plumb it if you had a raw water cooled engine?
I guess some of the newer heaters have a double walled heat exchanger coils, I'll check it out if I ever get around to changing the heater, but that'll involve cutting out the quarter berth bulkhead, and that puts it waaay down the to-do list.
Back to my original question, does anybody know anything about the Quick Sigmar heaters?
