The technology is relatively simple. Only the recent exposure of our fossil fuel shortage and dwindling world supply has brought prices in line and forced the question of how long conventional heating systems can be fueled. U. S. Weather Bureau data on solar radiation show that practical solar heating can be accomplished in the Mid-west. The price of a solar heating system is determined by variables such as type of building and desired system capability. Cost of operation, today and tomorrow, must be considered.
Solar energy is free and inexhaustible.
The initial cost of a solar heating system can be justified by life cycle cost analysis. The pay back time is within a reasonable number of years.
