I think this is as close to a build and forget as you can get. No moving parts and mostly plastic. Could put some septic Microbe starter in it, let them tend to the cleaning. Be easy to add a small pump to use the water for irrigation
I'll box it in with Styrofoam with the other four barrels to keep the heat in, later.
Right now, I'm trying to figure out how to get the best heat exchange. The coil well pick up some heat but the length only holds about a gallon. If the waste water in the barrel was in motion the coil would pick up more heat. Maybe a air stone.
Next thought would be to put a small metal tank about five gallon, in the barrel in front of the coil to keep the cold water in the warm wast water longer. Like a small bulk storage warming up.
