Affordable Earth-Air Heat Exchange System Saves Energy Costs

November 21, 2013

geothermalAffordable Earth Tubes, a type of geothermal system, have been used for decades to cut energy costs up to 80% in well insulated homes. While geothermal systems are very efficient and effective the cost can often outweigh the benefits.  A large system of tubes requires a large amount of property to be dug up. This excavation can be very cost prohibitive as well as severely scar the landscape. Complications multiply when there are a large amount of trees or rocky soil where the system needs to be installed. While certainly not the most efficient of the geothermal systems, our research on Earth-Air Heat Exchange Systems has convinced us that this smaller type of system adds great value for a cost that is well within reach of modest budgets, especially when installed in new construction. For existing homes with a crawl space, the retro-fit project will prove more complicated, but worth investigating.
