Abstract
A heat trap apparatus for a water heater is provided. The heat trap apparatus includes a tubular body, a liner disposed within the tubular body, and a heat trap baffle assembly having a tubular housing coaxially disposed within the liner. The liner includes a projection to engage with an inner surface of the tubular body at a first end using an interference fit. The tubular housing includes a first diametric portion to engage with the inner surface of the tubular body at a second end using an interference fit, a second diametric portion extending from the first diametric portion and to engage with an inner surface of the liner using an interference fit, and a third diametric portion extending from the second diametric portion and to movably support one or more heat trap inserts to inhibit convective fluid flow therethrough.
