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 (COP 4.4) delivers conditioned air throughout the home via ducts; an ERV provides fresh air to the system.
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
These plots compare sizing approaches in terms of the approximate annual heating load a heat pump might carry throughout the year for a hypothetical home in Minneapolis, MN.
Image
This “high static ducted cassette” heat pump system is similar to a traditional centrally ducted system, serving several areas of a home from one indoor unit
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 cold-climate heat pump can meet >90% of this home’s heating needs, even in Cordova, Alaska.
Image
This cold-climate heat pump provides heat at 77% capacity at 5°F, and 57% of capacity at -5 °F.
Image
This cold-climate heat pump provides heating and cooling for a home in Cordova, Alaska.
Image
This ducted mini-split heat pump was installed in the unvented, conditioned attic and ducted with short duct runs to several nearby rooms.
Image
This ductless wall-hung indoor unit has supplemental air filters (outlined in red), which only filter a portion of the airflow; most of the air bypasses the supplementary filters and only passes through the standard mesh filters.
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 multi-split heat pump system incorporates several indoor units connected to just one outdoor unit; the indoor units include a wall-mounted unit, floor-mounted, ceiling cassette, and mini-air handler.
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
