maalämpöpumpuiksi

Maalämpöpumppu, or geothermal heat pump, is a renewable energy system that utilizes the stable temperature of the earth to provide heating and cooling for buildings. The principle relies on the fact that the ground temperature remains relatively constant throughout the year, typically between 5-12 degrees Celsius. A geothermal system consists of a ground loop, a heat pump unit, and a distribution system. The ground loop, usually consisting of pipes buried underground, circulates a fluid (often a mixture of water and antifreeze) to absorb heat from the earth during winter and dissipate heat into the earth during summer.

In heating mode, the fluid from the ground loop transfers its absorbed heat to the heat pump. The heat pump then compresses a refrigerant, increasing its temperature significantly. This heat is then transferred to the building's heating system, such as underfloor heating or radiators. In cooling mode, the process is reversed. The heat pump extracts heat from the building and transfers it to the fluid in the ground loop, which then dissipates the heat into the earth.

Maalämpöpumput are known for their high energy efficiency, as they move heat rather than generate it through combustion. This leads to reduced energy consumption and lower heating and cooling costs compared to conventional systems. They also have a long lifespan and require minimal maintenance, contributing to their popularity as a sustainable and cost-effective solution for climate control in residential and commercial buildings. The initial installation cost can be higher than other heating systems, but the long-term savings and environmental benefits often make it a worthwhile investment.
