Wrong: Not enough space was left in the floorplans for both the heat pump water heater and a duct elbow to be attached to the right side of the water heater (the orange circle outlines the tank; the rectangle shows the space needed for the duct)

Wrong: Sized per Approach 1 or 2, this heat pump’s modulating zone has a small overlap with the home’s heating load line, resulting in a large amount of short-cycling; the unit will require backup heat when the temperature is below 25°F

Wrong: Sized per Approach 3, there is minimal overlap between this heat pump’s modulating zone and the home’s heating load line, causing excessive short-cycling; it will require backup heat and may not contribute significantly at temperatures below 5°F
