Wärmekreise
Wärmekreise, also known as thermal loops or heat circles, are a concept often discussed in the context of building heating systems. They refer to the circulation of heated water or other heat transfer fluids within a closed system designed to distribute warmth throughout a structure. The fundamental principle involves a heat source, such as a boiler or heat pump, which heats the fluid. This heated fluid then travels through a network of pipes, releasing its thermal energy to the spaces it passes through, typically via radiators or underfloor heating elements. Once the fluid has transferred its heat, it returns to the heat source to be reheated, thus completing the loop.
The design and efficiency of Wärmekreise are crucial for effective and economical heating. Factors like pipe
