Maalämmöllä

Maalämmöllä refers to geothermal heating or cooling systems that utilize the stable temperature of the earth as a heat source or sink. This technology, also known as ground-source heat pumps, involves a network of pipes buried underground to exchange heat with the soil or groundwater. In winter, the system extracts heat from the ground and transfers it into the building for heating. In summer, the process is reversed; heat is extracted from the building and dissipated into the cooler earth, providing cooling.

The installation of a maalämmöllä system requires drilling or excavation to place the underground loop system. This can involve vertical boreholes, horizontal trenches, or a pond loop depending on the available space and geological conditions. The heart of the system is a geothermal heat pump, which uses a refrigerant cycle to concentrate and transfer heat. While the initial investment for a maalämmöllä system can be higher than conventional heating and cooling methods, its long-term operational costs are significantly lower due to its energy efficiency.

Maalämmöllä systems are recognized for their environmental benefits. They produce fewer greenhouse gas emissions compared to fossil fuel-based heating systems and reduce reliance on electricity from the grid, especially when that electricity is generated from non-renewable sources. The lifespan of the underground components is typically very long, often exceeding 50 years, making it a sustainable and durable solution for climate control.
