Optimal Energy drills through bedrock at Busy Beaver

Did you know that Busy Beaver installed geothermal heating and cooling in the new Logan Square button building?  When rehabbing the two flat, vintage storefront we decided it was a good idea to save money and energy at the same time.

How does this system work?  Wikipedia describes geothermal energy as, “heat retained within the Earth’s core since the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface.”
