CO₂ water-to-water heat pump COOLSHIFT M for heating an office and warehouse building
Efficiency boost with ejector lift
A CO₂ heat pump with ejector lift replaces an oil-fired boiler: using groundwater, solar power, and innovative technology, TEKO’s system heats an office and warehouse building efficiently and sustainably—with up to 15% higher efficiency!

CO₂ water-to-water heat pump for heating an office and warehouse building
The goal of this project was to use available groundwater to provide an eco-friendly, energy-efficient heating solution for an office and warehouse building—while replacing the outdated oil-fired boiler.
The solution
A CO₂ water-to-water heat pump from TEKO
By using the natural refrigerant CO₂, integrating the ejector, and harnessing the fundamental energy sources of groundwater and solar power, the building’s heating system is implemented in an efficient and sustainable way.
