Image
A central heat pump water heating system with a parallel loop tank temperature maintenance configuration uses a multi pass heat pump water heater to provide all the heat for hot water circulation temperature maintenance.
Image
A central heat pump water heating system with a parallel loop tank temperature maintenance configuration uses a multi-pass heat pump water heater to provide all the heat for hot water circulation temperature maintenance
Image
A central heat pump water heating system with a temperature maintenance swing tank configuration uses the water from the primary storage tank to provide most of the heat for hot water circulation temperature maintenance
Image
A high-efficiency gas boiler provides hot water to the faucets, to radiant heating loops in the basement floor, and to a hydro-coil for a central air heating system.
Image
All of the pipes are insulated on this high-efficiency 50-gallon heat pump water heater.
Image
Basic components of a gas tankless water heater include a high-powered burner, fan, and heat exchanger; condensing gas water heaters also have a secondary heat exchanger and a piped air intake to the sealed combustion chamber
Image
Central heat pump water heaters like this fully packaged system provide efficient, reliable domestic hot water for multifamily buildings; storage tanks are within the enclosure, and the heat pump is seen just outside.

Image
On-demand hot water pumps speed hot water to faucets at a push of a button to limit water waste and save energy.
Image
Pipe insulation helps retain heat in the pipes which provide hot water from the air-to-water heat pump for domestic hot water and space heating.
Image
Image
Right - A home-run (also called central manifold or parallel piping) system distributes hot water directly from a distribution manifold next to the water heater to each fixture using individual small-diameter PEX pipes.
Image
Right - The geothermal heat pump provides hot water for radiant floor heating, domestic hot water, and the air handler for space conditioning upstairs.
Image
Right - The home’s high-efficiency gas boiler provides domestic hot water as well as in-floor radiant heat, while a high-efficiency heat pump provides cooling and a secondary source of heating.
Image
Right – Hot water from this heat pump water heater is distributed efficiently to each hot water use in the home through a central manifold via PEX piping.
Image
Right – PEX piping speeds hot water directly from the water heater to faucets through the attic in this slab-on-grade home.
Image
Right – The heat pump water heater is equipped with a recirculating pump to push hot water to distant fixtures.
Image
Image
Right: Maintenance valves are installed at the inlet and outlet of this central heat pump water heater
Image
Image
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
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 home’s domestic hot water is provided by three systems: solar water heating panels, a heat pump water heater, and an air-to-water heat pump, which also provides hot water to a fan coil.
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
This utility room houses a high-efficiency gas boiler to provide hot water for the radiant floor heating system and faucets. It also has a central air source heat pump and an energy recovery ventilator.
Image
This wall-mounted high-efficiency condensing gas tankless water heater has PVC vent pipes and insulated water pipes
Image
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

Wrap batt insulation around pipe loosely enough not to compress the insulation and secure with wire or tape
Image
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: The exhaust air from one heat pump water heater is blowing into the intake of the heat pump water heater next to it
