I got an ecotech hot water heater heat pump last year. It was made around 1999 and appeared to have barely been used when I got it. I got it going late last summer then put it in dry storage over the winter. This time I added an over sized filter and a duct to blow the cool air out of the hot water heater closest. The condensates are still collected into a 1 gallon milk jug, need to install an actual condensate pump since I have a drain and a 120v receptacle in the closet. The hot water heater heat pump kills 4 birds with one stone. It provides: hot water Intermittent air conditioning It eliminates a major 240v load Eliminates scale deposits that accumulate in the bottom of the hot water heater.
