Hello all -

I'm looking at homes in Central Pennsylvania.

A new one I will be checking out has the following:
R-49 insulation, geo-thermal heating, solar panels.

How does geothermal heating work, vis-a-vis a "standard" hot
air or hot water heat system? Do they actually save any
money in heating costs?

These may look attractive when new, but what are the
long-term maintenance costs?


In theory, geothermal heating (or cooling) pre-heats (or cools) the
air to the temperature of the earth underground - usually about 56F.
So, if the ambient temperature is, say, freezing, the air gets
raised to 56F before regular heating kicks in.




Your heybub version seems to work a little differently than actual
geothermal heating systems...

Agreed. I apologize for the confusion.

My facts were wrong but the narrative was correct.
