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?
