    Two Burnham oil fired, hot water boilers, lost in 16 years. Boiler # 1 lost in 3 years, Boiler # 2 lost this year, 14 years old,. Cracked cast iron section. Model # PV78WCTBWN.
    Piped beautifully, 5 circulators, 27 zone valves. Sits a large 6 car garage at the back adjacent to inside basement wall. Provides domestic hot water to an 80 gallon SuperStor Ultra. Any ideas?

    Thermal Shock

    Thermal shock would be my first suspect.
    Condensation would be the next.
    Is it radiant heat?
    Do you have pictures or drawing of the piping?

    Cracked section?

    Where? On right side above cleanout? If so,it's quite common on V7 boilers
