How warm does geothermal heating get?
For direct use of geothermal heat, the temperature range for the agricultural sector lies between 25 °C (77 °F) and 90 °C (194 °F), for space heating lies between 50 °C (122 °F) to 100 °C (212 °F). Heat pipes extend the temperature range down to 5 °C (41 °F) as they extract and "amplify" the heat.
How much money can you save by using geothermal energy?
