Abstract
Disclosed herein are heat pump systems for water heaters. The heat pump systems can comprise a housing defining an interior chamber, an air inlet, and an air outlet. The air inlet and the air outlet can form an air flow path through the interior chamber, and an evaporator unit can be positioned within the interior chamber such that the air flow path contacts the evaporator unit. The housing can also have a flue pipe having a cross-section to encourage aerodynamic flow and/or side baffles to encourage air flow into the evaporator unit. The housing can also have a second air inlet to increase air flow and a curved elbow around the first air inlet to direct the air flow path. The air flow path can flow from a top side of the housing to a side of the housing, and the air flow path can be reversible.
