Maapohjalämpöpumpun

Maapohjalämpöpumppu, often referred to as a ground source heat pump, is a renewable energy system that utilizes the stable temperature of the earth for heating and cooling buildings. This system consists of a buried network of pipes, a heat pump unit, and a distribution system within the building. The underground pipes, known as a ground loop, absorb solar energy that has been stored in the soil or bedrock. Even in colder climates, the earth's temperature remains relatively constant, typically between 7-12 degrees Celsius (45-54 degrees Fahrenheit) at a sufficient depth.

The heat pump unit, located inside the building, is the core of the system. It contains a refrigerant that circulates through the ground loop. In heating mode, the refrigerant absorbs the heat from the earth loop, which is then compressed to a higher temperature. This heat is then transferred to the building's heating system, such as radiant floor heating or forced-air systems. In cooling mode, the process is reversed. The heat pump extracts heat from the building's interior and transfers it to the ground loop, effectively cooling the space.

Maapohjalämpöpumput are known for their high efficiency and low operating costs compared to traditional heating and cooling methods. They have a long lifespan and require minimal maintenance. The initial installation cost can be higher due to the excavation required for the ground loop, but the long-term energy savings and environmental benefits often make it a cost-effective solution. They also have a minimal environmental impact, as they do not produce on-site emissions.
