Built for greater demand
More capacity. One coordinated system.
Larger buildings need a heating system that can respond to changing demand throughout the day. ETERA-C brings multiple geothermal heat pumps together in a coordinated cascade, with the configuration selected around the building and its available heat source.
For commercial premises, shared facilities and larger residential properties, it offers a modular approach to heating, cooling and hot water. Individual units are connected on site, creating a neatly integrated installation that is easier to transport and assemble.
- Cascade capacity selected around the project
- Ground collector and groundwater options
- Heating, cooling and hot water capability
- Remote access through CLOUD.KRONOTERM
Key benefits
Greater demand, intelligently managed
Capacity that fits
Combine heat pumps to suit the building’s calculated demand, with coordinated operation as heating requirements change.
Stable renewable energy
Draw on energy stored in the ground or groundwater, using a heat source selected for the site.
Modular installation
Separate units are transported into the building and connected on site, simplifying handling and plant room assembly.
Considered acoustic design
Insulated housings and vibration management help limit sound within the building.
Year-round versatility
Bring heating, cooling and hot water into the system design, with equipment selected for each requirement.
Connected visibility
Review operation and adjust settings remotely, helping building operators stay informed and supporting technical diagnostics.
Best fit applications
Ground source thinking for larger buildings
From busy workplaces to larger residential properties, ETERA-C offers a flexible starting point for projects with higher heating demands and a suitable ground or groundwater source.
Coordinated cascade operation
Multiple units, working together
ETERA-C coordinates individual heat pumps as demand changes. A multi-unit arrangement can also support continuity during maintenance, with the available capacity determined by the units remaining in operation.
Modular by design
A considered approach to the plant room
Modules connect on site, with matching panels completing the installation. The coordinated design creates an orderly plant room arrangement, while removable heat pump modules support access for servicing.
Connected system management
Stay close to performance
CLOUD.KRONOTERM provides remote access to settings and operating information. Review schedules, monitor performance and give technical teams the visibility they need to investigate issues and refine system operation.
