Portions of the tubes are bent to form a plurality of openings extending through at least one of the boundary walls. Some of the bent tube portions extend around the openings in the plane of the wall, and others of the bent tube portions extend out of the plane of the wall. The tubes, including the bent portions, extend at an angle with respect to a horizontal plane for their entire lengths to enable the tubes to drain. A burner is associated with each opening to apply heat to the enclosure, and fluid is passed through the tubes to apply heat to the fluid.
