Kiertoketjutermillä

Kiertoketjutermillä, also known as closed-loop geothermal systems, are a type of geothermal energy system that uses a closed loop of fluid to transfer heat from the ground to a building. The system consists of a loop of piping that is buried underground, with a heat pump located inside the building. The fluid in the loop, typically a mixture of water and antifreeze, is circulated through the pipes, absorbing heat from the ground and transferring it to the heat pump. The heat pump then uses this heat to warm the building in the winter, and in the summer, the process is reversed to cool the building. Kiertoketjutermillä systems are highly efficient, as they can extract heat from the ground at a constant temperature, regardless of the outdoor temperature. They are also environmentally friendly, as they do not release greenhouse gases or other pollutants into the atmosphere. However, they require a significant upfront investment and may not be suitable for all types of buildings or climates.
