3.  Heated by liquid or air in solar energy collectors.  Collect and absorb solar radiation.  Transfer solar heat directly to the interior space or to a storage.  Heat is then distributed.

4.  Cost-effective in cold climates with good solar resources.  Displace more expensive heating fuels, such as electricity, propane, and oil.  Some states offer sales tax exemptions, income tax credits or deductions, and property tax exemption.  Life span-decades  Reduce air pollution.  Reduce GHG.  Reduce heating bills.

5.  High initial costs.  Limited location.  Solar cells can only produce direct current.  No sun- rely on other energy resource.  Some carbon

6.  Collectors and storage unit.  Stored in hot water tank.  Available hot water when needed.  Closed system.

7.  Increases oil life which is not as reliant.  Decreases costs of heating.  Efficiency
