Abstract
A water heater has a heat exchanger positioned within a water tank and connected to an inlet for combustion gases for heating the water within the tank. The heat exchanger has a cylindrical first flue extending downwardly from the inlet with a lower end terminated at a 45-degree first bevel cut. Short fins are fixed to the interior of the first flue. A second cylindrical flue of the same diameter as the first flue extends upwardly parallel to the first flue, and has a 45-degree second bevel cut at its lower end. Longer fins are welded to the interior of the second flue. A cross flue extends between and is directly connected without elbows to the lower ends of the two flues and has 45-degree bevel cuts which are welded to the bevel cuts of the two flues. The right-angle connection of the flues facilitates a compact water heater arrangement.
