Thanks for the posts guys, this has really got my squirrel cage a turnin'. I haven't had a chance to check on the flow requirements for our particular situation but one GT unit I was browsing claimed they ONLY used 2 cfm of water for operation or about 15 gallons per minute. I expect ours would be quite a bit more than that because the house is bigger than most of the case studies I've looked at. We have a separate pond water pump and pressure tank system and pickup already installed. I may have to draw off the pond for household water and just use the well for drinking water and the heat pump.Is anyone else set up for pond water household supply? Does the hot water side of the unit care where the water comes from or is limited to just the well source? Chip
