Le marché des pompes à chaleur dans les nouveaux immeubles d'habitation en Allemagne (en anglais)

Selon le bureau fédéral allemand des statistiques, la part des pompes à chaleur utilisées comme dispositif principal de chauffage dans des immeubles résidentiels neufs était de 32.2% en 2013 - une augmentation de 2% par rapport à 2012.
According to the German Federal Bureau of Statistics, the share of heat pumps used as primary heating device for newly constructed residential buildings was 32, 2% in 2013 - a gain of 2% compared to 2012.
Trend towards air-source heat pumps

The market share of aerothermal heat pumps further increased. In 2013, 22,9% of the new residential buildings were equipped with heat pumps that use air as heat source. By contrast, the segment of geothermal systems continues to decline. Their market share fell from 10% in 2012 to 9,2% in 2013. In 2010, areo- and geothermal heat pumps had similar shares - with 14,8% for the former and 14,1% for the latter technology.

According to Karl-Heinz Stawiarski, CEO of the German heat pump association (BWP), the main reasons for that development are a) easy access of air as heat source and b) increased efficiency of aerothermal systems. However, he highlights the additional advantages of geothermal heat pumps: The soil offers a constant temperature level of around 10°C. Especially on warm summer days that provides a very efficient and environmentally friendly way cooling the building. In addition, a ground-coupled heat pump is a durable investment: it can last up to 100 years and add value to an equity for decades.
