It seems like a "long" time ago I read an article about a guy ( I believe it was Popular Mechanics) who mounted a car radiator in his air duct and ran well water through it. I believe you would just have to run the water pump whenever the fan was running. The house thermostat could control this. You want to keep the water in the heat exchanger as cold as possible for best efficiency. Just be sure the recovery rate of your well is sufficient to supply your system. ----- Original Message ----- From: Rick C.
