Comprehensive Chiller-Heater Systems

Trane® Comprehensive Chiller-Heater systems, featuring electric heat pumps, provide cost-effective, energy-efficient, reliable cooling and heating, while reducing carbon emissions. Ideal for larger buildings, especially those with hydronic systems, these pre-engineered solutions make electrified HVAC systems easier to specify and implement. We offer multiple options and variations, so that more buildings in more places can maintain year-round comfort while working to reach their decarbonization goals.

Key Benefits:
  • Becomes part of the climate solution as utilities produce cleaner electricity
  • Cleaner electricity generation: fuel transformation for building electrification can help meet tighter regulatory requirements, avoid carbon penalties and achieve sustainability goals
  • Electrified hydronic heat pump systems can reduce or replace fossil fuels for heating in buildings, cutting down on direct carbon emissions
  • Comprehensive Chiller-Heater systems maximize performance by combining knowledge and expertise into the controls, equipment selection, and system layouts

System Advantages

Trane Design Assist


Comprehensive Chiller-Heater Systems can help you meet diverse heat and cooling loads. These flexible systems can be combined with virtually any hydronic heating and cooling solution, with option to address indoor air quality through improved filtration, air cleaning and variable ventilation.


Comprehensive Chiller-Heater System controls allow you to consistently maintain high performance by managing equipment capabilities and limitations properly to serve changing conditions. It also allows you to design for redundancy and defrost management, as well as to maintain comfort as loads fluctuate throughout the day.

Comprehensive Air-to-Water Heat Pump Systems

The basic Trane Comprehensive Chiller-Heater System packages best-in-class air-to-water heat pump equipment and controls and applies technical expertise to deliver an industry-leading electrified solution for almost any building.  This electrified system works with many existing hydronic airside systems, offering configurations and options to fit a variety of applications. 

Thermal Battery™ Storage-Source Heat Pump Systems

This innovative cold climate heat pump system captures and stores excess heat energy from inside the building and outdoor air for use the next day. Heat energy is stored and dispatched in thermal energy storage tanks— “ice tanks.” The ability to store heat enables the system to work effectively in very cold climates. It is also an ideal fit in dense urban areas where limited rooftop space can’t accommodate large rooftop equipment.
