The use of geothermal energy for more localised energy requirements is becoming more apparent with the use of geothermal heat pumps. The use of heat from the upper portion of the earth's crust can be useful and efficient method of energy saving. At around 50 m below the earth's surface the ambient temperature fluctuates between around 8-12 oC. This heat can be used by being transferred to the surface via a loop system using a high-efficiency refrigerant type of material.These systems are also typically more efficient than gas or oil-fired heating systems. They are more energy efficient than air-source heat pumps because they draw heat from, or release heat to, the earth, which has moderate temperatures all the year, rather than to the air. Geothermal heat pumps use the relatively constant temperature of the ground or water several meters below the earth's surface as source of heating and cooling. Geothermal heat pumps are appropriate for retrofit or new homes, where both heating and cooling are desired. In addition to heating and cooling, geothermal heat pumps can provide domestic hot water. They can be used for virtually any home size or lot in any region of the Czech Republic. |
