Heat trap apparatus for water heater

A water heater comprising:

• a tank;
• one or more heat trap apparatuses mounted on the tank;
• and
• one or more conduits fluidly coupled to the one or more heat trap apparatuses, wherein each of the one or more heat trap apparatuses comprises:
• a tubular body configured to fluidly couple with one of the one or more conduits, the tubular body comprising:
• a first end;
• a second end disposed opposite the first end;
• an inner surface extending from the first end to the second end;
• and
• an outer surface extending from the first end to the second end;
• a liner disposed within the tubular body, the liner comprising:
• a tubular wall;
• and
• a projection extending radially outward from the tubular wall and configured to engage with the inner surface of the tubular body at the first end of the tubular body using a first interference fit;
• and
• a heat trap baffle assembly comprising a tubular housing coaxially disposed within the liner, the tubular housing comprising:
• a first diametric portion configured to engage with the inner surface of the tubular body at the second end of the tubular body using a second interference fit;
• a second diametric portion extending from the first diametric portion and configured to engage with an inner surface of the liner using a third interference fit;
• and
• a third diametric portion extending from the second diametric portion and configured to movably support one or more heat trap inserts to inhibit convective fluid flow therethrough.
