It would be unwise and against code to duct garage air into the house. A HP water heater also can not be hidden in a closet as it needs lots of air movement to work correctly. If you are not willing to place the unit inside conditioned space (to help with cooling load) then you are likely better off with an on-demand water heater. The cheaper efficient option.
