ABSTRACT:
A combinational fireplace arrangement has a plurality of log-shaped members having a hollow center portion with a spiral shaped tube passing serially through each of the logs, which tube conveys a fluid through the log-shaped members. A first fuel burning member, within the log member, heats the fluid passing through the spiral shaped tubing. An arrangement of pipes, encased with heat collectors, placed in the fireplace flue, captures energy escaping from the logs and preheats the fluid. A second fuel burning member, controlled independently from the first, is placed beneath the logs to cause the logs to appear to be burning. A thin gauge twisted pair of copper wire within the spiral shaped tube eliminates the formation of air pockets therein.
