Lämpökaivoihin

Lämpökaivoihin, or geothermal wells, are boreholes drilled into the earth to access geothermal energy. This energy is derived from the Earth's internal heat, which is a continuous and sustainable resource. The temperature of the ground increases with depth, and lämpökaivoihin tap into this temperature gradient to provide heating and cooling for buildings.

The process typically involves drilling one or more wells to a significant depth, often hundreds of meters. A closed-loop system of pipes, usually filled with a fluid like water or an antifreeze solution, is then installed within these wells. This fluid circulates, absorbing heat from the surrounding rock and soil in the winter, and dissipating heat into the ground in the summer.

The absorbed heat from the ground is then transferred to a heat pump located within the building. The heat pump uses a refrigeration cycle to concentrate this low-grade heat and raise its temperature to a level suitable for space heating. In cooling mode, the process is reversed, with the heat pump extracting heat from the building and transferring it to the fluid in the lämpökaivoihin, which then dissipates it into the cooler earth.

Lämpökaivoihin offer an environmentally friendly and energy-efficient alternative to traditional heating and cooling systems. They significantly reduce reliance on fossil fuels, leading to lower greenhouse gas emissions and reduced energy costs for consumers. The initial investment in drilling and installation can be substantial, but the long-term operational savings and environmental benefits make them an attractive option for many.
