ABSTRACT:
Apparatus is provided for heating liquid, utilizing a power burner for burning a combustible fuel. Elongated pipes comprising a flue and a water jacket extend horizontally from the power burner, the flue and water jacket being long enough so that at least some of the exhaust products of combustion exiting through the flue are cooled below the dew point of water so that the latent heat of vaporization from these exhaust products is transferred to the water circulating in the water jacket. A baffle is disposed within the interior of the flue for effecting gas turbulence to maximize heat transfer. The end of the flue remote from the burner has a glass lining to prevent corrosion of the flue from condensate formation, and a condensate drain is provided. The drain includes a U-tube with limestone chips or the like disposed therein for neutralizing condensate flowing through the U-tube. Spaced C-shaped components partially surround the flue and function to space the water jacket from the flue and provide a water baffle. A tubular coil of heat-conductive material is disposed in an enlarged portion of an exhaust conduit extending from the flue, and is connected up to the domestic hot water supply to obtain further heat recovery from the exhaust gases. Efficiencies of greater than 90% can be obtained.
