Trane® Domestic Hot Water Heat Pumps
Enhance energy savings with a water-source heat pump for domestic hot water.
- 150% more efficient than electric resistance water heaters without using fossil fuels
- Produces water up to 160°F (71°C) at water source temperature 35°F (2°C)
- Combined COP between 3.5-6
- Monobloc design for stacked units with zero clearance, minimizing the footprint in your building
-
Energy Efficient
Saves energy by using heat in your building that would otherwise be wasted. More sustainable than gas boilers and 150% more efficient than electric resistance water heaters. Supports electrification and sustainability goals.
-
Space-saving Design
Monobloc system allows you to fine tune to the capacity you need, all within a reduced footprint with stacked or zero clearance installs. The unit’s modular design means fewer components, easier integration and faster commissioning, whether in a new build or retrofit.
-
High Temperature
Delivers domestic water up to 160°F (71°C) at 35°F (2°C) source temperature. Ideal for large commercial buildings, multi-family housing, hotels, hospitals, government and office buildings, assisted living facilities, hydronic free cooling applications, geothermal and district energy systems and more.
-
Single Pass or Multi-Pass System
Available in multi-pass for operations facing installation challenges and/or requiring precise temperature control. Or select a single pass system for improved efficiency, reduced energy use, less equipment wear and more consistent water temperature.
-
Integrated Solution
Can capture and repurpose heat from chillers and cooling towers, further boosting energy efficiency. BACnet connectivity enables control through a building management system or the included tank sensors.
-
Single Supplier for Hot Water and HVAC
Combining Trane heat pumps for domestic hot water with a Trane chiller system means you can rely on one trusted supplier for support and service across your building systems. Backed by Trane’s national sales and service support network and 2,900 factory-trained technicians.
