Boiler Fundamentals and Best Practices

Sep 21, 2003 · Most boilers are configured for flow from the bottom return to the top supply. The location of the high limit control on the majority of boilers is near the top supply tapping. Piping the boiler with the return in the top supply tapping will wash the high limit with cooler return water and cause an override of the desired high limit temperature.

Direction of tankless hot water coil leaks into vs. out of a heating boiler or indirect water heater tank. This article explains conditions under which the direction of a hot water coil leak can reverse from its expected behavior and how that condition may be detected. We explain that an indirect or hidden coil leak usually increases boiler temperature but when building water supply pressure is lost the leak can reverse and may contaminate the building potable water piping or water
