I am interested to hear other people's experiences with IBC BOILERS as a result of the dangerous issues that we have faced. Carbon Monoxide was pumped into our home over a period of nine months, after the new boiler was installed. Installer couldn't figure it out - exhaust lines extended so that there wasn't a re circulation of exhaust. Power supply was addressed (battery backup installed) and that wasn't the issue. The efficiency was tuned down (so much for high efficiency). That wasn't the issue. Finally the manufacturer admitted the problem was widespread - a faulty processor. Fire Department was called out TWICE to our home. Now its only a year later (two years after install) and the heat exchanger goes. IBC says not a warranty issue because our system - which had been purged prior to install, wasn't clean enough. Clearly this is not a good choice for a home, or as a replacement boiler. We don't trust it and are wondering if we bite the bullet and rip it out and install something else? A Lennox? Interested in other experiences.
