Sustainable heating with outside air

Air-source heat pumps use energy from the outside air to heat residential buildings efficiently and in a climate-friendly manner, and also to cool them when necessary. They are versatile, relatively easy to install and suitable for both new builds and renovations of single-family homes, two-family homes and small apartment buildings.

For builders and operators, air source heat pumps offer a future-proof alternative to fossil fuel heating systems.

Who are air-source heat pumps suitable for?

Air-source heat pumps are particularly suitable for:

  • Single-Family Homes
  • Two-family homes
  • New build projects
  • Renovations requiring simple retrofitting

Thanks to the use of outside air as a heat source, no earthworks or well drilling are necessary, which is particularly advantageous for properties with limited space.

How do air-source heat pumps work?

An air-source heat pump extracts thermal energy from the outside air and uses a refrigeration cycle to raise it to the temperature level required for heating and hot water.

Modern systems operate reliably and efficiently even at low outside temperatures. Thanks to their flexible application options, air source heat pumps are among the most commonly used types of heat pumps in private residential construction.

Advantages of air-source heat pumps in private housing projects

  • Use of a universally available, renewable energy source
  • Comparatively low investment costs
  • Simple and quick installation
  • Suitable for heating, hot water and optional cooling
  • Compliance with legal requirements for renewable energies

Monobloc - compact and easy to install

Monobloc heat pumps combine all refrigeration components in a single enclosed outdoor unit. This makes them particularly easy to install and ideal for new construction and renovation projects in private residential buildings. Since no refrigeration work is required on site, installation is simplified and commissioning is quick and safe.

Monobloc air-source heat pumps can be installed in a space-saving manner, work reliably with outside air as a heat source and are a proven solution for single-family, two-family and small multi-family homes. In our range, you can recognise monobloc heat pumps by the suffix ‘Bloc’ in their name.

Important aspects of planning and implementation

When selecting and planning an air-source heat pump, builders should pay particular attention to:

  • Building condition and heating system (flow temperatures)
  • Correct dimensioning of the system
  • Installation location
  • Professional installation and commissioning

Careful planning ensures that air-source heat pumps operate efficiently and quietly.
