Generated explanation

The illustration shows a storage water heater connected to a separate add-on heat pump by water lines. Blue arrows indicate cold water flowing from the bottom of the tank to the heat pump, while red arrows show heated water returning to a connection at the tank's cold-water inlet piping. Separate top connections supply cold water to the tank and deliver hot water to fixtures. The heat pump takes in warm room air, discharges cool air, and has a condensate drain line and an electrical power connection. A note explains that some systems connect both heat-pump water lines to the bottom of the tank; no defect is depicted.
