Ruud Air to Water Heat Pump
Where Energy Efficiency is Essential, Air to Water Heat Pump offers up to 150°F outlet water temp in a Super-efficient, Super-compact Package
Key Features
Highly Efficient
Delivers hot water with a system Coefficient of Performance (COP) exceeding 4.0 at 80°F ambient and 60% relative humidity. Heat pumps can also be used as a preheat to other fuel types. Contributes to the overall increase in building efficiency and can qualify for LEED points. HPHD135 models are ENERGY STAR® certified.
Installation Flexibility
Available models and options to meet the diverse needs of every building, the heat pump takes gas lines and flue venting out of the equation. It can be installed indoors or outdoors with a choice between vertical and horizontal discharge models. Optional kits are available to connect ductwork for ducting cool discharge air, as well as stacking kits to stack horizontal discharge models, saving valuable floor space.
Suits Most Mild Climates
The heat pump will efficiently perform in ambient temperatures down to 40°F. For colder days, it includes an auxiliary boost mode and auto defrost. In addition, it features an epoxy coated evaporator coil which provides extra protection in coastal and non-coastal environments.

Performance Data
Performance Graphs
HPHD-60 Heating COP Graph: This graph illustrates the relationship between Ambient Temperature (F) on the x-axis and COP and Capacity (BTU/h) on the y-axis. It shows increasing COP and Capacity as ambient temperature rises.
HPHD-135 Heating COP Graph: Similar to the HPHD-60 graph, this shows COP and Capacity (BTU/hr) versus Ambient Temperature (F), indicating performance trends.
System Diagram
The diagram illustrates the water flow and connections for the Air to Water Heat Pump system. It shows the direction of flow for cold water supply, primary flow, primary return, hot water flow, and hot water return. Key components include the A2W Heat Pump, Primary Pump, Storage Tanks, and connections to the building's hot water supply and return. It also indicates the location of a Building Hot Water Temp Sensor and a Tank Thermostat Sensor, along with the Electrical Supply and Heat Pump LAN Connection.
