How Does Geothermal Heating Work - A Website That Describes Geothermal Energy
How does geothermal heating work
Though geothermal heating has been suggested as a potential technology to resolve the global energy crisis, many of us aren’t aware as to how does geothermal heating system work. In this heating system, air is circulated from inside the Earth’s surface to heat or cool a house.
Geothermal heat refers to heat kept inside the Earth’s surface. The term geothermal is derived from the Greek words, geo for Earth and thermos for heat. As per evidences, heat energy in the deep underground results from the decay of radioactive particles and absorption of solar heat. The average temperature of geothermal heat is fifty - seventy degrees Fahrenheit. This geothermal energy can be used as an alternative energy source for heating homes and home gadgets.
Geothermal Heating
Geothermal heating is an sophisticated leading edge technology implemented for clearing up the worldwide energy crisis. It gets use from geothermal energy for heating or cooling applications. As of now, it has succeeded in providing more than 0.07 p.c of the global energy consumption. In a geothermal heating system, the heat energy contained inside the Earth’s surface is used for heating purposes. It is also referred to as ground source heat pump. The standard geothermal heating system has the capacity to heat up a building without using other heating appliances. Let’s see in a nutshell how does geothermal heating system work.
Working of Geothermal Heating System
For better knowledge of the working of a geothermal heating system, first let’s discuss about its main components. In this heating system, there are three primary parts, namely, a geothermal heat pump, ground loop system and a distribution system. The geothermal heat pump is installed within the house or property, while the ground loops or pipes are configured under the Earth’s crust at a particular depth. The depth of the piping depends upon the chance of geothermal heat in the particular area.

The pipes of the ground loop are connected to the geothermal heat pump and the distribution system is configured as per the need of the user. The heat pump forces a liquid refrigerant or cool water into the pipes of the ground loop, which is then circulated underground. The refrigerant is heated up naturally due to geothermal heating inside the Earth’s surface. The heated water is circulated back to the heat pump that exchanges the heat by employing a heat exchanger. This heat exchanger then circulates warm air within the house via the distribution system.
Speaking about the uses of geothermal heating system in hotter months, this will be operated for cooling a place similar to air conditioners. The working principle of the system is reversed so that heat exchanger now supplies cool air in the house. For setting the desired temperature, an electronic thermostat is configured in the system, which heats or cools the house in an appropriate way. This is in brief an answer to how does a geothermal heating system work.
Since the heat exchanger is operated by using electricity, the final working of geothermal heating system consumes some amount of energy. However, it is terribly cost effective to use geothermal heating in comparison to other heating systems. Geothermal heating system is more successful in areas that lie close to the plate tectonic bounds. Over these regions, the heat-laden magma frequently rises close to the earth’s surface. In such cases, geothermal heating can be effectively used for heating water.
One of the major advantages of geothermal heating is that it is renewable and eco-friendly. It is replaceable since heat encircled inside the Earth’s surface may be employed for both cooling or heating purposes. Also, unlike the other traditional heating appliances, operation of geothermal heating system doesn’t emit poisonous gases or contaminants.
