Wärmestegen

Wärmestegen is a term used in certain regions, particularly in German-speaking countries, to describe elevated walkways or platforms designed to capture and retain solar heat. These structures are often found in agricultural settings, such as greenhouses or along garden beds. The primary function of a Wärmesteg is to absorb solar radiation during the day and then slowly release this stored heat into the surrounding environment, typically at night or during cooler periods.

The construction of a Wärmesteg can vary, but it commonly involves materials that have good thermal mass properties. Dark-colored stones, concrete, or specialized heat-retaining materials are often employed. The elevated design allows for better air circulation beneath the structure and can also contribute to the even distribution of heat. In some applications, these walkways might be integrated with a system for cultivating plants, providing a warmer microclimate for their growth.

The benefit of using Wärmestegen lies in their ability to extend the growing season, protect sensitive plants from frost, and potentially reduce the need for artificial heating in controlled agricultural environments. They are a passive solar design element that harnesses natural energy to moderate temperature fluctuations. While the term itself might not be universally recognized, the concept of using thermal mass for temperature regulation is a well-established principle in sustainable design and agriculture.
