wherein said inlet return port directs said previously circulated fluid to an upper portion of said boiler chamber for complete mixing with said fluid in said boiler chamber.

2. A boiler according to claim 1 , wherein said metering means is modular in design for accommodating boilers of differing sizes.

3. A boiler according to claim 1 , wherein said metering means includes a tubular portion having a distal end of reduced diameter, said distal end having extension openings therein for joining successive sections of tubular portions to one another.

4. A boiler according to claim 1 , wherein said burner element is disposed below said boiler chamber.

6. A boiler having a boiler chamber within which a fluid is heated by a burner element, said boiler being supplied with previously circulated fluid, said boiler comprising: a housing having an inlet return port formed therein, said inlet return port being in fluid communication with said boiler chamber; and a metering means for providing controlled turbulence to thoroughly mix said fluid in said boiler chamber with said previously circulated fluid; and

wherein said metering means is disposed in said inlet return port and comprises a tube having apertures therein for passage of said previously circulated fluid therethrough whereby said previously circulated fluid does not ‘overwhelm’ said fluid in said boiler chamber thereby preventing the creation of new temperature striations therein.

7. A boiler having a boiler chamber within which a fluid is heated by a burner element, said boiler being supplied with previously circulated fluid, said boiler comprising: a housing having an inlet return port formed therein, said inlet return port being in fluid communication with said boiler chamber; and a metering means for providing controlled turbulence to thoroughly mix said fluid in said boiler chamber with said previously circulated fluid; and

wherein said inlet return port is oblong in profile and said metering means includes a tubular portion having spaced-apart mixing apertures for the exit of said previously circulated fluid as orthogonal moving jets of higher pressure and velocity which impact the walls of said inlet return port whereby the turbulence created thereby increases the rate and mixing within said inlet return port to harmonize the temperature striations within said boiler chamber.

9. A boiler having a boiler chamber within which a fluid is heated by a burner element, said boiler being supplied with previously circulated fluid, said boiler comprising: a housing having an inlet return port formed therein, said inlet return port being in fluid communication with said boiler chamber; and a metering means for providing controlled turbulence to thoroughly mix said fluid in said boiler chamber with said previously circulated fluid; and

wherein said metering means includes a tubular portion having means for joining successive tubular portions thereto for increasing its length to accommodate boilers of various dimensions.

10. A return temperature stabilizer assembly for a boiler wherein fluid disposed within a boiler chamber is heated by a burner element, circulated within a mixing chamber and mixed with cooler inlet fluid, said return temperature stabilizer assembly being disposed in an inlet return port in fluid communication with said boiler chamber, said temperature stabilizer assembly including metering means for providing controlled turbulence to thoroughly mix said fluid in said boiler chamber with said cooler inlet fluid while reducing temperature striations; and

wherein said inlet return port directs said cooler inlet fluid to an upper portion of said mixing chamber for complete mixing with said fluid in said mixing chamber.
