Engineers and armchair experts, could someone run the numbers on this for me?
The water coming out of my tap is cooler than my home. If I hooked up a garden hose to the drain of my baseboard water heating system, flushed the room temperature water out of the house and into my yard, thus replacing the water in the system with fresh, cool, tap water, could I generate a significant cooling effect (thus, taking pressure of my AC unit)?
Would any heat transfer into the pipes? Would a fan on the pipes make a difference?
