They're talking about 176F. Superheated.
Call that guy Neil Chayett(SP) on his “looking at the law” radio show, it was his house.
What I was told was the water is warm enough to prevent your pipes from freezing in the winter, and cool enough to ac the house in summer. All free, after the 20k hole is paid off.
To be superheated it would have to be over 212 degrees F.
Superheated means that the water has been heated above the boiling point for water at a given pressure.
