Geothermal energy or geothermal power is in fact Earth’s thermal energy that is generated by heat stored beneath the Earth’s surface. Since geothermal power has great potential, we’ll take a look here at its main advantages when used for heating.
Probably the biggest advantages of geothermal heating are low heating costs (cost savings can be as much as 80% over the fossil fuels) and it also uses significantly less electricity than standard heating systems. Geothermal heating uses Earth’s heat which is a renewable energy source.
When it comes to efficiency geothermal energy is 48% more efficient than gas furnaces and even 75% more efficient than oil furnaces. There are also very low levels (sometimes none) of the air pollutants and greenhouse gases making it from this point of view as highly ecologically acceptable solution.
Not only that geothermal heating system heats the house but it cools it as well and operates very quietly. There is also uniform heating meaning there’s no cold and hot spots and of course there are no furnaces or chimney to clean after. Maintenance of geothermal heating system is also very cheap since it requires only changing the heat pump unit’s air filter. Geothermal heating system can be also introduced into the existing home, especially if there’s forced air duct system and its underground piping has lifetime of over 50 years.
