Maapohjalämpöpumput

Maapohjalämpöpumput, also known as ground source heat pumps, are a type of geothermal heat pump that utilizes the stable temperature of the earth for heating and cooling. These systems typically consist of a ground loop, which is a network of pipes buried horizontally or vertically in the ground, and a heat pump unit located inside the building. The ground loop circulates a fluid, usually a mixture of water and antifreeze, which absorbs heat from the earth during winter and releases heat to the earth during summer.

The heat pump unit then transfers this absorbed or released heat to or from the building's heating and cooling distribution system, most commonly radiant floor heating or forced air. During the winter, the heat pump extracts heat from the ground loop and transfers it to the building, providing warmth. In the summer, the process is reversed, with the heat pump absorbing heat from the building and transferring it to the ground loop, thus cooling the interior.

The efficiency of a maapohjalämpöpumppu relies on the consistent temperature of the earth, which remains relatively constant year-round, unlike the air temperature which fluctuates significantly. This makes them a highly energy-efficient and environmentally friendly option for climate control. Installation involves drilling or excavation to place the ground loop, which can be a significant initial investment. However, the long-term savings in energy costs and reduced carbon footprint often make them a cost-effective solution over the lifespan of the system. Regular maintenance is recommended to ensure optimal performance and longevity.
