Conventional Energy Wells
Conventional shallow wells are used in combination with a heat pump. They are suitable for heating and cooling houses with one single well, or larger buildings with fields of up to several hundred wells. An anti-freeze fluid is usually circulated in these wells to transfer the heat from under the ground to the surface.
The wells we have developed go beyond the conventional: they go deeper. By drilling deeper, more energy can be extracted without the need for a large surface area. This is a big advantage in areas where there is limited available space. Since the temperature in the wells is higher, the heat can be transferred with clean water instead of an anti-freeze fluid. This also makes it possible, in some cases, to use the heat directly without a heat pump, such as keeping a surface free of ice in the winter.
