Inspired by: While under construction, my shower was drained directly to the outdoors. In winter I could see my money for the water heater's propane being totally wasted as the hot drainwater melted ice which would soon freeze over, and I could witness the noxious fumes from the heater. Multiplied by the tens of millions of homes. Had to try something.
