My Water Furnace
This cool little company in Alpena, Michigan, Terra Caloric, makes a product called Well Connect.
This Open Loop Geothermal machine, extracts heat from well water to heat your house.
We installed one at our place near Gaylord, Michigan in September of 2018.
Here is a link to some YouTube video’s about this amazing unit
I saved more than $1000 in propane in our first heating season.
