 Not sure about this, but the hot water option may only function properly if your system uses a conventional hot water tank. You mention a green home, so I suspect you may have a 'tankless' or on demand hot water heater? If so, I'd research that a little more before purchasing the 'hot water option'. Besides, that involves another bit of additional plumbing and possibly another booster pump, pressure switch, etc.
