Size comparison between two 50-gallon water heaters: a traditional electric-resistance-only water heater on the left and a heat pump water heater on the right
Image
The cool exhaust air from this heat pump water heater is ducted out of the room, inducing warmer intake air to enter through a wall grille
Image
The Energy Guide label on this heat pump water heater shows a first hour rating of 60 gallons; the low Estimated Yearly Energy Cost of $121 reflects the HPWH’s high Uniform Energy Factor (UEF) of (not shown on label)
Image
Image
The heat pump water heater’s evaporator fan provides enough air movement for active ventilation of a small room when the exhaust is ducted; intake air enters passively through a wall grille
Image
The small heat pump located on top of the tank on a heat pump water heater extracts heat from the surrounding air to create hot water
Image
The ultra-efficient air-to-water heat pump draws heat from the outside air to heat inside room air in winter and domestic hot water year-round.
Image
The ultra-efficient ground-source heat pump provides the home with forced-air heating and cooling, and hot water.
Image
The very high efficiency (4.7 COP) ground-source heat pump provides hot water to a tank for radiant floor heat and domestic hot water.
Image
This central heat pump water heating system with a hot water circulation loop that returns to the primary storage tank relies on a single pass heat pump to provide both primary DHW heating and hot water circulation temperature maintenance
Image
This central heat pump water heating system with a hot water circulation loop that returns to the primary storage tank relies on a multi pass heat pump to provide both primary DHW heating and hot water circulation temperature maintenance
Image
This fully packaged/skid-mounted central heat pump water heating system was shipped to the building on a truck and craned into location
Image
This fully specified central heat pump water heating system has four individual outdoor heat pump units plumbed in parallel to indoor storage tanks
Image
This heat pump water heater has been fitted with ducts to exhaust its waste cooling into the occupied living area
Image
This Heat Pump Water Heater has Pipe insulation installed on the hot water line (on left) and on the cold water line (on right)
Image
This heat pump water heater is centrally located in a laundry room so that all hot water uses are less than 15 feet from the tank.
Image
This Heat Pump Water Heater is Sitting on an Insulation Pad to Reduces Heat Losses
Image
This home is equipped with an ultra-efficient (COP 5.7) ground source heat pump, which also provides domestic hot water that is stored in a tank.
Image
This home’s ultra-efficient ground-source heat pump provides hot water for space heating as well as domestic hot water for the 50-gallon storage tank.
Image
This is the compact outside unit for an ultra-efficient air-to-water heat pump (COP 4.1) that provides space heating and domestic hot water.
Image
This mechanical room contains both the storage tanks (right) and heat pumps (left) of a central heat pump water heating system
Image
This packaged central heat pump water heating system has the heat pumps on the exterior of the blue enclosure, and the storage tanks, temperature maintenance equipment, mixing valve, and control modules on the inside
Image
This retrofit central heat pump water heater system utilizes the existing water heater as a swing tank to provide temperature maintenance for the hot water circulation loop
Image
Types of heat pump water heaters commonly used in central heat pump water heating systems include single pass units, multi pass units, and integrated units
Image
Image
Wall grilles installed high and low on the wall of the heat pump water heater closet allow passive ventilation of a small room with warmer air coming in at the top and cooler exhaust air exiting at the bottom of the wall
Image
Wrong: HPWH inlet and outlet are piped to mixing valve inlet and DCW make up, driving erratic HPWH and mixing valve behavior
Image
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)
Image
Wrong: The exhaust air from one heat pump water heater is blowing into the intake of the heat pump water heater next to it
