Ok I have searched high and low but can't seem to find a viable solution to this. I recently fired my furnace up for the upcoming cooler days and nights and need some help. We only choose to heat our water during this time (fall/winter/early spring) and use our water heater during the warmer months. My wife is convinced that our water quality changes as soon as I start heating our water with the furnace. She states that it makes her hair different. I can't tell any difference personally but I'm a guy and I don't pay attention to that stuff. Thanks for any help. Heatmaster MF5000
