Geothermal Design - Installation

When considering the installation of a new heating system give geothermal a look. With today's federal and local rebates, it can actually cost less to go with a geothermal heating system rather than the best propane or oil system. Benefits include minimal reliance on fossil fuels, cleanest energy available and a typical fuel savings annually of 50%.


To give those interested a better understanding of Geothermal Heating, I have decided to offer a look into this technology and its benefits. The featured home is a new 2 story, 1800 square foot home being constructed with optimum energy efficiency in mind here in the Lakes Region.

Step 1. System Design: The design of a geothermal heating system is specific to each individual home. Windows, doors, insulation r-values and the building envelope are important features to consider when designing a system.
