2. How It Works Anti-freeze/water in boreholes (heat exchanger).
Grout around boreholes- helps heat transfer.
Cold air from house is taken through hot pipes.
Reversible direction for seasons.

3. How It Works Fans toggle direction/keep moving. Ground water.
More efficient (lowers around 40 degrees).
Any temperature of air/water to get heat.
