Years Payback Time. Payback periods for single components are between 6-50 years.

Long payback periods are due to two factors:

  1. Carbon neutral heating and cooling uses expensive electrical power versus non-expensive natural gas.
  2. The installation of a ground source heat pump and high-performance insulation are still very costly.

Government incentives as well as decreasing cost due to higher demand would shorten payback periods significantly.
