A method of storing thermal energy in a body which is in direct thermal contact with the surrounding earth. The energy is transferred to said ground body from heat absorbing devices, specifically solar heat absorbing devices, by circulating a liquid in a circuit incorporating a plurality of channels in the ground body and said heat absorbing devices. The thermal energy stored in the ground body is removed therefrom by means of the circulating liquid and used to control the heat of an object such as a building by circulating the heated liquid around the building in a further circuit incorporating further channels and heat emitting devices. The channels in the ground body are arranged and sized in accordance with the calculated amount of thermal energy supplied to and taken out of the ground body period such as one year. A defined surface surrounding the ground body is established at a distance from the most remote of the channels in a direction outwardly of the ground body so to reach a maximum temperature on the order of 35°C. and a temperature variation during the period of energy input and output of not more than 10°C.

A method of establishing a heat-storage zone in the earth which can be supplied with heat from heat-absorbing means during one season of the year and from which heat can be taken in another season of the year for distribution to heat-emitting means in a building or similar structure with the heat storage zone having sufficient capacity to store all of the heat necessary for the building during said another season without raising the temperature at the periphery of the storage zone in the earth above about 35°C. with the variation of the temperature at the periphery of the storage zone not to exceed 10°C. during the year, said method including the steps of: forming a plurality of channels in the earth with the channels spaced a distance s from the periphery of the storage zone and a distance not exceeding 2s from one another, said distance s being approximately one (1) meter in the case of earth rich in water to approximately three (3) meters in earth which is relatively dry and rock such as granite, providing a liquid conduit between said heat-absorbing devices, said heat-emitting devices and said channels, and circulating said liquid between said heat-absorbing devices and said channels during one season of the year to store heat in said heat storage zone and circulating said fluid between said channels and said heat-emitting devices during another season of the year to remove heat from said heat storage zone.
