Why Choose a Full-Inverter Heat Pump?

COP Efficiency in the Belgian Climate

At an ambient temperature of 15°C, a high-end inverter heat pump achieves a COP of 7 to 10, delivering up to 10 kW of heat for every 1 kW of electricity consumed.

  • Up to 60% energy savings compared to On/Off models
  • Ultra-low noise level (down to 20-25 dB at 10 meters)
  • Longer compressor lifespan thanks to soft-start tech
  • Seamless solar panel integration
