Trane® Domestic Hot Water Heat Pumps
Capture wasted heat and turn it into savings.
Help Reduce Energy Costs with Water-Source Heat Pump Technology
Is your water heating system dragging down the energy efficiency of your building? In many facilities, gas boilers account for 4% to 37% of total natural gas consumption for water heating, depending on the building type.1 Besides being less efficient than other heating systems, gas boilers contribute significantly to CO₂ emissions, making it more challenging to meet sustainability goals.
While electric water heaters provide a cleaner alternative to gas, they still lag in efficiency. Whether you're designing a new building or it's time to replace your existing building's aging boiler system, consider this a great opportunity to help increase overall energy efficiency and reduce operational costs by integrating a heat pump water heating solution into your HVAC system.
Trane Domestic Hot Water Heat Pumps (DHWHPs) offer a cleaner, more sustainable solution that eliminates fossil fuel use and is about 150% more efficient than electric water heating systems. Instead of generating heat, they maximize efficiency by moving it.
The Least Expensive BTU is One That's Already Created
Trane DHWHPs capture excess heat from external water sources – such as lakes, rivers, wells, underground pipes or engineered water loops – and transfer it to the water in the tank. The domestic heated water can be used for various applications such as bathing, cleaning and cooking.
This efficient approach helps reduce energy consumption while providing the same amount of hot water compared to conventional systems.
Engineered to Serve a Range of Applications
Trane DHWHPs can seamlessly integrate with your building's HVAC system, capturing and repurposing excess heat from the chiller to reduce chiller loads and enhance overall efficiency. These domestic hot water heat pumps are also compatible with district energy systems and can support a geothermal loop, delivering ultra-efficient water heating, even from sources as low as 35°F (2°C).
Producing water temperatures up to 175°F (79°C), Trane DHWHPs are ideal for commercial buildings with typical hot water needs, such as:
- ? Large commercial buildings
- ?️ Multi-family housing
- ? Hotels
- ? Hospitals
- ?️ Government and office buildings
- ? Institutional facilities
- ? Nursing homes and assisted living facilities
Other Applications Include:
Low-Temperature Comfort Heating Loop
In buildings that utilize low-temperature fluid for heating, typically produced from an air-to-water or water-to-water heat pump chiller, Trane Domestic Hot Water Heat Pumps can be integrated into the heating distribution loop to source heat for the water heater.
Water-Source Heat Pump System Loop
Trane Domestic Hot Water Heat Pumps can extract thermal energy from a water-source heat pump loop in a building. This loop typically circulates water through a network of distributed heat pumps used for space heating and cooling, allowing the water heater to utilize the relatively stable temperatures of the loop to efficiently heat domestic water.

Easy Setup, Easy Startup
The monobloc design of Trane DHWHPs allows for stacked units with zero clearance, reducing their footprint in your building. Plus, they're available in multiple models to meet specific system demands.
And because they're preconfigured at the factory for integration into an existing HVAC system, installation and commissioning are smooth and straightforward. All models include open-source BACnet communications protocol for connectivity and advanced staging with virtually all building management system (BMS) controls.
