Thanks for all the knowledgeable advice. I also envision a 1000 gallon poly water tank with a float valve to even out demand on our well. If the water in the cooling loop gets too hot, I could put some of that room temperature water from the reservoir tank into the condenser and replace it with water circulating through the cooling loop to get me through the run. Like you mentioned, I could lose some hot water into the cooker. Just got to figure out how to plumb it. I'm thinking about maybe 600 ft of slinky pipe in the ground. In 3' slinky loops, that should fit into a 100' trench. I could always add more if I had to. Doesn't seem like the condenser on a 2-300 gallon still would require all that much cold water. Anybody have any more thoughts?
