In the study of alternative energy sources, especially for a
private home, I came across such topics as geothermal heat
from the ground. As far as it became known during the study
of the issue, the earth freezes over in winter, only 1.5-2
meters, the temperature does not drop below 5-7 degrees.
This allows you to lay pipes at a depth of 3 meters and pump
out warm air in winter and cool (like air conditioning) in
summer. |
