Gas Heating Option: The initial equipment and installment of the natural gas system would cost $210,000
right now. The maintenance costs of the equipment are expected to be $2,000 per year, starting next year,
for each of the next 18 years. The energy cost is expected to be $4,000 starting next year and is expected
to rise by 5% per year for each of the next 18 years due to the price of natural gas increasing.
Geothermal Heating Option: Because of green energy incentives provided by the government, the
geothermal equipment and installation are expected to cost only $170,000 right now, which is cheaper than
the gas lines. There would be no energy cost with geothermal, but because this is a relatively newer
technology the maintenance is expected to be $15,000 per year, staring next year, for each of the next 20
years.
