Image
Right: dedicated tank connections for HPWH inlet and outlet provide hydraulic separation
Image
Image
These schematics illustrate temporary deployment locations for probes during the commissioning process; these probes connect to smartphone commissioning applications.
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 nitrogen pressure test was completed on this ductless mini-split heat pump using a digital manifold gauge.
Image
A vacuum decay test is performed on this ductless mini-split heat pump using a digital micron gauge for accurate measurement; a deep vacuum is achieved quickly by using large diameter, vacuum-rated hoses, and removing valve cores
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
Image
Most residential heat pumps are installed incorrectly and with energy-wasting faults.
Image
Quality installation and commissioning are critical to optimizing heat pump performance.
Image
Right - The home’s ground source heat pump preheats water for the air source heat pump water heater.
Image
Right: Maintenance valves are installed at the inlet and outlet of this central heat pump water heater
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 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
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
