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?

Thanks,
- John
