Does anyone have or are you familiar with hooking a water line to a heat pump?
As a real estate broker, I saw one in a house about a year ago, and I plan to ride back out to see it again, but I don't remember many of the details other than it seemed like a great idea, & it worked - the actual water heater saw about 30% of normal use, as I recall.

Pretty simple concept, run the water through the heat pump, and have a recirculate-able holding tank, all tied into the hot water line to the house.

I have a dinosaur a/c unit, runs great (and A LOT!), just not efficient, and plan to replace shortly. I like this idea, and curious of downsides etc.

Thanks!
