Can’t stress enough, is the person who is working on your boiler licensed? Before you allow someone to work on your steam & hot water system, you should verify that they are licensed to do so.
Boilers can last most of a lifetime but they need to be taken care of. Annual temperature & pressure calibrations can make or break a system. Annual inspection of safety devices, as well as redundant safety devices are incredibly important for your safety and the safety of those around you. Air mitigation is a periodic must do also.
Some of the brands we recommend are Dunkirk, Intellihot and Lochinvar, but click here for more information about other brands of boilers.
