How long is the payback period for a geothermal system?
Geothermal systems are so
energy-efficient that the payback period is remarkably brief. A study by the
Air Force Institute of Technology calculated that it takes on average just
seven to eight years to recoup costs.
Your specific payback point
depends on factors like local utility rates, excavation/drilling costs, how
well your house is insulated, the efficiency of the model you choose, and what
incentives your state or utilities provide.
One of the best aspects about
geothermal is cash flow. If you install a geothermal system, the monthly
savings in operating costs generally offset the additional monthly financing
cost, resulting in an immediate positive cash flow – especially in a new home.
Again, your specific situation may vary.
