It’s CHEAPER than most other energy forms to make as well as being more efficient at its job of heating things. It’s smaller than a lot of heaters as well.The main disadvantage seems to be that it requires refrigerants to function. These are “fluids that absorbs heat at low temperatures and rejects heat at high temperatures” and are made of some pretty DANGEROUS chemicals such as chlorine. These would EFFECT the environment around geothermal heaters. Another ISSUE is that it is somewhat difficult to set up due to the piping and groundwork needed to set it up....
