CTC EcoAir 708M Air Source Heat Pump

The CTC EcoAir 708M is a state-of-the-art, high-efficiency air-to-water outdoor heat pump equipped with advanced inverter speed control. The defining feature of this outdoor unit is its utilization of propane (R290) as a refrigerant. R290 is a natural, eco-friendly substance with an incredibly low Global Warming Potential (GWP), cementing this heat pump as one of the most sustainable and carbon-reducing options available on the market for modern residential homes. Its intelligent compressor smoothly self-regulates its power output between 2 and 9 kW, eliminating energy-wasting on/off cycles while safeguarding core mechanical components against wear.

In addition to highly cost-effective space heating and domestic hot water generation, the CTC EcoAir 708M features an integrated cooling function. This allows the system to reverse its cycle and distribute active, gentle cooling throughout the home during hot summer periods to ensure premium indoor comfort all year round. Engineered to survive tough winters, the unit provides reliable operational stability in outdoor temperatures down to -25 °C. The unit is managed and automated by docking with compatible indoor system modules or smart external controllers.
