Geothermal Heat

Earth day is an annual and global event which falls on April 22. It devoted to helping the environment and making the world a greener place. Everyone can make a difference on this day. Only by recycling your garbage you can save many plants and animals all over the world.

On this day I have decided to write about something I truly believe in: geothermal heat. As many of you might know, the earth is incredibly warm underneath the surface and by using pipes and pumps we can transfer this heat into houses and other buildings. There is a huge difference between the amount of Fahrenheit we have on the surface of the earth and only a few feet below our feet. Another advantage with a geothermal heat pump is that the temperature under the surface is quite constant even though the climate above can change drastically. The heat varies from 45*F to 75*F depending on the latitude. The temperature works similar to a cave, it is warmer than the air above it in the winter and cooler in the summer.

The installation price for a geothermal heat pump is a lot more expensive than an air source system and this is the reason why many people won’t install it in their own house. However, the costs are returned to you in energy saving after 5 to 20 years. The geothermal heat pumps are also quieter, lasts longer, and need little maintenance.

This is some of the reasons why I believe in this energy source and why I would like to install one in my house when I get one. I think more people should install one as well. Today there are 50000 heat pumps in the USA but I believe that is too few. What do you think about the geothermal heat pump?
