IBC SL Boiler Reviews

"Constant Repairs Needed"

1.0 rating
Very Unsatisfied

We had an IBC Boiler installed and it has been in need of constant repair. There hasn't been a season yet that it needed work to be done for the winter season and then through out.
Parts are hard to find when you contact the Manufacturer you don't get replies back. Very hard to find replacement parts.
