Definitions
- the present invention relates to new and improved gas fired fluid heating apparatus useful in providing hot water on demand and having notable utility in providing hot water for home heating and other home uses.
- FIG. 2 is an enlarged elevation section view, partly broken away and partly in section, of an embodiment of a gas fired water heater employed in the hot water supply and heating system;
- the combined stack and heat exchanger unit 16 has a lower flange or collar 60 for securing the stack to the upper end of the fire box housing ls and an upper flange or collar 62 for securing a suitable exhaust conduit 64 to the upper end of the stack 16.
- the combined stack and heat exchanger 16 comprises a plurality of elongated coaxial tubes -73 including an inner tube 70 providing a central exhaust passageway 74, an outer cylindrical tube 73 and a pair of intermediate cylindrical tubes 71, 72.
- the first inner tube being formed with at least one helical convolution extending along a substantial portion thereof and providing corresponding helical grooves on the inner and outer surface thereof for causing generally swirling motion of the hot exhaust in the inner exhaust tube and generally helical flow of fluid around said inner exhaust tube, a third outer tube and a fourth tube intermediate the second and third tubes and defining therewith respectively longitudinally extending intermediate exhaust and outer fluid passageways.
