The science behind geothermal heat pump systems is fairly simple. All you need to know are a few basic concepts:
Learn how heating and cooling efficiency is measured.
Find out what goes on below the frost line.
Soil & Rock
Heat transfer is crucial to a geothermal system.
Geothermal antifreeze solutions are biodegradable, non-toxic and non-polluting.
A duct system can make a big difference in both cost and effectiveness.
