Living in and with nature

Redevelopment

12 opinions, one solution

Using a clever redevelopment strategy, the owner of the “Alte Schmitte” development in Lohn-Ammannsegg replaced the power-hungry electric heaters of the 1980s with efficient and economical geothermal heat pumps from CTA. Each flat now has a heat pump that is roughly the size of a wardrobe. For heating and hot water, these use heat from a geothermal probe field common to each building.
