indirect tank boiler piping heat transfer question
For a typical indirect domestic hot water tank, hot water from boiler goes in (5) and flows in a coiled loop then exits tank (6) and goes back to boiler.
question is wouldn't u want hot boiler water entering near the bottom of the indirect tank or specifically nearest where the potable cold water inlet enters the tank? In doing so wouldn't there be a greater temperature differential and better heat transfer?
