CTC EcoPart i425 Pro Ground Source Heat Pump 25 kW

The CTC EcoPart i425 Pro is a robust, high-capacity brine-to-water heat pump (ground, borehole, or lake source) delivering an output of 25 kW, engineered for large residential complexes, commercial properties, and agricultural facilities. The Pro model stands out from standard configurations due to its integrated advanced automation hub, the CTC EcoLogic Pro system. This smart controller allows the unit to act as the primary master controller for the entire utility plant, regulating hydronic distribution across up to four separate climate zones, solar panels, auxiliary heat sources, buffer tanks, swimming pools, and passive cooling loops while managing up to nine other secondary heat pumps in a cascaded network.

The mechanical loop features dual low-noise scroll compressors paired with separate, heavily sound-insulated cooling modules, allowing the CTC EcoPart i425 Pro to step up its output capacity in three distinct stages. This ensures a smoother overall operation with fewer energy-wasting on/off cycles, protecting internal components against premature wear and maintaining steady climate comfort. For lowest possible running costs, the unit is fitted with A-rated low-energy circulation pumps on both the brine and heating medium sides. By omitting an internal domestic hot water cylinder, it provides a highly versatile, space-saving design. It effortlessly delivers high flow temperatures up to 65 °C, supporting both underfloor heating grids and high-temperature radiator networks.
