Before we know it, much like seeing a new water main or sewer main going into a downtown city street, we will see geothermal main lines installed in our communities. The time is coming when energy companies will charge for BTUs exchanged rather than for fossil fuels combusted.
It is counterintuitive for tradespeople who work with boilers and know how to create heat through combustion of fossil fuels to understand that heating can be accomplished with electrically driven heat pumps.
Air-source geothermal heat pumps are absolutely necessary to help us attain the goal of zero on-site admissions. They provide a terrific amount of site-sourced energy from the ambient air and the earth beneath our buildings.
