Massachusetts regulates boilers and pressure vessels through the Board of Boiler Rules under 522 CMR. Inspections are done by Department of Public Safety Engineering Division inspectors or authorized insurance inspectors, and the state licenses boiler operators as engineers and firemen. We prepare boilers for inspection and complete the repairs needed to return them to service.
Worcester sits higher and farther inland than Boston, and its winters are colder and snowier, with heating design temperatures near 0 °F. Boilers run under heavy, sustained load from late fall through early spring, which wears on refractory, tubes and burners. Problems often start elsewhere in the system, so we check condensate return, feedwater and traps along with the boiler itself.
