Air-to-water heat pump in integral construction- 6-9 kW heat output.

You can’t get more quiet and flexible.

M Flex 6-9 is an air-to-water heat pump for heating purposes, consisting of a compact outdoor unit and a space-saving indoor unit.

With a heat output of 6-9 kW, M Flex is the perfect solution for detached and semi-detached houses or even flats. For new buildings, renovations or modernisation. M Flex is less complex than comparable heat pump systems yet remains hugely flexible. Domestic hot water cylinders and central ventilation can be individually added, too. This enables M Flex to be adapted to your construction project at any time

  • Maximum flexibility. Domestic hot water cylinders or central ventilation can also be planned and ordered independently of M Flex. This means you can react flexibly to changes at short notice before installation.
  • High level of integration. All relevant components are already integrated. As so much is ready-assembled ex works,

    installation is quick and easy.

  • Extremely quiet. The outdoor unit has been specially optimised for installation close to walls. The special owls’ wing fan provides a naturally quiet sound. The compressor has been deliberately shifted into the indoor unit. This keeps noise emissions to a minimum, even at full heat output.
  • Efficient. With inverter technology. The heat pump output is intelligently adapted to actual heat or hot water consumption. Verifiable efficiency thanks to certification measurement.
  • Eligible for subsidies. When old oil heating is replaced, the investment costs are subsidised by the state by BAFA, The Federal Office for Economic Affairs and Export Control. . Up to 35%

    in existing and new buildings. High CO2 savings compared to fossil heat generators.


  • Attractive design. Compact format. The M Flex design features reassuringly high-quality materials, clearly accentuated surfaces and excellent workmanship. The indoor and outdoor unit have an extremely space-saving design.
