  • Fireplace heating system
    Patent number: 4008703

The pipes are arranged in upper and lower sections that provides a pair of closed paths in which air is circulated by a fan. Cast iron slugs are spaced within the pipes in order to transfer heat to the circulating air and to increase the air turbulence.
