ABSTRACT:
A combinational fireplace arrangement has a plurality of log-shaped members having a hollow center portion with passageways through the bottom thereof for permitting air to pass upwardly through the log-shaped members into the hollowed center portion thereof. The log-shaped members also have a plurality of holes extending through the upper portion thereof from the hollowed center. A spiral shaped tube passes serially through each of the logs which tube conveys a fluid, such as water, through the log-shaped members. A fuel burning member, such as a gas burner, extends through the hollowed portion of each log-shaped member along the longitudinal axis defined by the spiral tubing. The fuel burner generates a flame which simultaneously heats the fluid passing through the spiral shaped tubing and generates a flame which passes upwardly through the holes to give the appearance that the log-shaped members are burning.
In an alternate embodiment of the invention, cylindrical members are utilized having the aforementioned structure with solid log-shaped members positioned on top thereof to give the appearance of burning logs while at the same time heating a fluid such as water passing through the center of the cylinders.
