  • Patent number: 7401742
    Abstract: A temporary heating apparatus comprises a portable heat exchanger which transfers heat from a hot fluid circulating in a primary circulation loop thereof to a heated liquid circulating in a secondary circulation loop thereof. The heat exchanger is connectable to a hot fluid source such that hot fluid from the hot fluid source circulates through the primary circulation loop. A portable remote heating unit comprises a fluid coil releasably connected by flexible conduits to the secondary circulation loop, and a secondary pump is connected to the flexible conduits and the secondary circulation loop to pump heated liquid through the secondary circulation loop, flexible conduits, and the fluid coil of the remote heating unit. The heat exchanger isolates the heating circuit from the hot fluid source, allowing the use of steam as the hot fluid source, and further allowing high pressures in the heating circuit, such as encountered in tall buildings.
