Maavesilämpöpumppujärjestelmä

Maavesilämpöpu is a term of Finnish origin that generally refers to a system that utilizes the thermal energy stored in the ground or groundwater for heating and cooling purposes. The fundamental principle behind maavesilämpöpu, also known as geothermal heat pumps or ground-source heat pumps, is to extract this ambient thermal energy and transfer it to a building. This is achieved through a network of underground pipes, a heat pump unit, and a distribution system within the building.

In a typical maavesilämpöpu system, a fluid circulates through the underground pipe loop, absorbing heat from the earth. In colder months, this absorbed heat is then transferred to a heat pump, which uses a small amount of electricity to concentrate the heat and raise its temperature to a level suitable for space heating. Conversely, in warmer months, the process can be reversed to extract heat from the building and dissipate it into the ground, providing cooling.

The effectiveness of maavesilämpöpu depends on factors such as ground temperature, soil type, and the amount of land available for the underground loop. While the initial installation cost can be higher than conventional heating systems, maavesilämpöpu systems are known for their energy efficiency and low operating costs, leading to significant long-term savings on utility bills and a reduced carbon footprint. They are considered a sustainable and environmentally friendly alternative for climate control.
