Geothermal heat pumps

Maalämpö toimii hyödyntämällä maaperään varastoitunutta uusiutuvaa lämpöenergiaa. Energiakaivon tai maapiirin kautta kerätty lämpö siirtyy lämpöpumpulle, joka kompressorin avulla nostaa lämpötilan vesikiertoiseen lämmitykseen ja käyttöveden tuotantoon. Järjestelmä toimii ympäri vuoden, myös pakkasilla.

The installation of a geothermal heat pump includes drilling a heat well or installing a horizontal circuit, installing the heat pump device itself in the technical space, as well as connecting the water circuit and electrical work. The installation usually takes 2–4 working days and requires both interior and exterior work. The work is carried out as a turnkey contract by specialized installers.

Ground source heat pumps are very popular in Finland, as the ground temperature remains constant throughout the year. Finnish conditions are particularly well suited to borehole solutions, which offer high efficiency even in winter. Their use is also supported by a long service life and a clear reduction in energy costs.
