Plumas, Lassen, Sierra and Washoe counties are ideal climates for GeoExchange technology, similar to the upper Midwest, Canada and Sweden.
A properly designed system can heat a well-insulated building in sub-zero weather where stored underground thermal energy averages 40°F or better.
Heat Transfer Principles
- Heat moves from warmer to cooler areas.
- Greater temperature differences increase heat-transfer rates.
Below the frost line (3 to 5 feet deep), ground temperatures in this region remain between 35 to 50°F, allowing ground source heat pumps to operate more efficiently than traditional systems.
