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.
A combinational fireplace arrangement comprising at least one log-shaped member having a hollowed center portion and having means for transferring air from below the log-shaped member to said hollowed center portion thereof and having aperture means extending from said hollowed center portion to the outside of said log-shaped member proximate the top thereof, means for supporting said at least one log, a spiral shaped tube extending within the hollowed center portion and substantially throughout the length of said at least one log, and a fuel burning means extending along the longitudinal axis defined by said spiral tubing, said fuel burning means heating a fluid passing through said spiral tubing while at the same time generating the flame which passes through said apertures upwardly away from said log-shaped member to give the appearance of a burning log.
A combinational fireplace arrangement having at least one hollow cylinder, said cylinder having means for transferring air from below said cylinder to the center portion thereof and having aperture means extending from the center thereof to the outside proximate the top thereof, means for supporting said at least one cylinder, a spiral shaped tube extending within and substantially throughout the length of said at least one cylinder, a fuel burning means extending along the longitudinal axis defined by said spiral tubing, said fuel burning means heating a fluid passing through said spiral tubing while at the same time generating a flame which passes upwardly through said apertures, and at least one non-combustible log positioned with respect to said cylinder, said flame passing upwardly from said cylinder about said log to give the appearance of said log burning.
