FIELD: construction.
SUBSTANCE: method to use heat-accumulating properties of soil includes arrangement of tight heat exchangers in soil, for instance, heat wells, organisation of a coolant circulation in them and withdrawal from soil, and/or discharge of low-potential heat energy into soil. At the same time directed flow of ground waters is arranged in soil with the help of open wells, at least one of which is a water-intake well and one is for water injection, at the same time the ground water extracted from soil prior to its injection back into soil may be cooled, picking low-potential heat, or heated, discharging low-potential heat in soil.
EFFECT: higher power efficiency of using heat-accumulating properties of soil.
