The closest thing to air conditioning that nature offers us.
Geothermal machines combine the advantages and performance of heat pumps with the thermal inertia of the ground and interact by exchanging heat with it, achieving impressive savings of 80%.
There are also simpler geothermal installations without a heat pump, which extract the temperature using some fluid or air. Although this system may be insufficient, you need to support it with another auxiliary system.
Geothermal systems can be combined with the usual technologies and emitters such as underfloor heating, low-temperature radiators and fan coils.
With these systems we can also obtain domestic hot water.
