    TriangleTube Smart 40 - Insufficient Hot Water

    Problem: Although I have hot enough water, it just doesn't last. I have an indirect fired water heater, TriangleTube Smart 40, eight to nine years old. Boiler is Weil-McLain CGA6PIDN natural gas. I can't find anything wrong with the control circuits. Taco SR504-4 seems to be working properly...
