摘要

Heating unit of parent patent has the by-pass coil, which slows circulation, replaced, in the addition by a vertical tube which is fixed inside the external cylinder with its coaxial internal cylinder by the tubular arms. The vol. between the walls, is connected to the pump circuit by connectors. The assembly has a cover with an evacuation outlet for the fumes and hot gases from the high press. gas burner. The by-pass tube, connected to the heating circuit by the tubes, has a spiral sheet welded to its outer wall; this deflects the burnt gasses and improves the heating of the annular space. The unit quickly increases the temp of the contents of large tanks and reservoirs. It can easily be moved from one tank to another.
