Biasi Oil Boiler Service & Repair
Plenty of Biasi B-10 oil boilers are still heating Southern NH homes, and our technicians have spent decades working on them. Biasi is no longer sold as a new install in North America, but we keep existing systems running and source replacement parts when available. When replacement makes more sense, we evaluate the home and compare suitable current boiler options, which may include Saint Roch.
A Quick History of Biasi in NH
Biasi manufactured the B-10 as a cast-iron hot-water boiler with a three-pass, low-water-content design and oil- or gas-burner configurations. A.J. LeBlanc Heating services Biasi boilers throughout Southern New Hampshire, including equipment paired with Riello, Carlin, and Beckett burners.
Our technicians are factory-trained and certified on Carlin, Beckett, and Riello oil burners. We match the burner to the equipment and set up combustion for safe, proper operation within the manufacturer's specifications.
When a Biasi boiler can still be repaired responsibly, we explain the work and parts availability. When replacement makes more sense, we measure the home's heating needs and review the piping, venting, burner, controls, domestic-hot-water setup, and available space before comparing current boiler options.
Keeping Your Biasi Running
- Annual Biasi B-10 tune-ups and combustion analysis

Replacement Options for an Aging Biasi B-10
A Saint Roch SR Universal is one option we may compare for an aging Biasi because it is also a low-water-content, triple-pass cast-iron boiler with oil and gas configurations. It is not treated as an automatic drop-in replacement. Our Home Comfort Advisor sizes the new boiler for the home, and the written estimate identifies any piping, burner, control, venting, or domestic-hot-water changes required for the installation.
