Abstract

A combined heating system comprising a first heating subsystem including a first fluid conductor, a first heating unit adapted to heat a first fluid and output the first fluid at the outlet of the first fluid conductor, and a fluid mover adapted to move the first fluid through the first heating unit, a second heating subsystem including a second fluid conductor adapted to receive a second fluid, a third fluid conductor, a second heating unit adapted to heat the second fluid and output the heated second fluid in the third fluid conductor, a fluid mover adapted to move the second fluid from the outlet of the third fluid conductor to the inlet of the second fluid conductor, at least one heat exchanger operably connected to a downstream location of the first heating unit and a fourth fluid conductor connecting the second fluid conductor and the third fluid conductor.

Claims7

Dependent claims

A heating system for heating a fluid, said heating system comprising:

(a) a U-shaped fluid conductor comprising a first arm comprising an inlet and an outlet and a second arm comprising an inlet and an outlet, said first arm is configured for receiving the fluid at said inlet of said first arm and channeling the fluid to exit said first arm at said outlet of said first arm and said second arm is configured for receiving the fluid from said outlet of said first arm and emptying the fluid through said outlet of said second arm;
and
(b) at least one heating unit functionally coupled with a fluid mover, said at least one heating unit is configured to receive a portion of the fluid through said first arm at a location between said inlet and outlet of said first arm, add heat to the portion of the fluid to produce a heated fluid and return the heated fluid into said second arm at a location between said inlet and outlet of said second arm, wherein the heated fluid is emptied into said second arm to heat the fluid.

Dependencies are inferred from the claim text.
