CTC EcoPart 612M Ground Source Heat Pump

The CTC EcoPart 612M is a highly compact, premium brine-to-water heat pump (ground, borehole, or lake source) featuring advanced inverter speed control. This specialized unit is intentionally engineered for residential and commercial spaces with strict installation footprints, or setups where an independent domestic hot water tank is already present. By omitting an internal water storage unit and master screen interface, it achieves a low clearance height of just 760 mm, making it the perfect solution for low-ceiling basements or underneath pre-existing hardware. Its intelligent compressor continuously modulates its output between 2.5 and 11.8 kW to balance real-time energy draws, protecting components against wear.

The mechanical architecture is optimized for hybrid docking, working seamlessly alongside CTC indoor modules or external system control panels. For high-capacity property applications, multiple units can be easily cascaded together. Delivering flow temperatures up to 65 °C, it effortlessly supports both underfloor heating grids and traditional high-temperature radiator networks. To guarantee premium comfort inside the home, the scroll compressor and cooling loop components are fully enclosed within a heavily sound-insulated compartment, securing nearly silent operation.
