  • Myths and methods for protecting boilers against flue

    Here's a statement that is easy to remember: All boilers that aren't designed to operate with sustained flue gas condensation should be protected against sustained flue gas condensation. The latter includes almost all cast-iron sectional boilers, steel boilers and copper tube boilers. These boilers are not intended to operate with sustained flue gas condensation.
