Common Steam Boiler Problems & How to Troubleshoot Repairs

How a Steam Boiler Works. Steam boilers use a contained heat system to generate steam. The steam travels through pipes in the building's walls where they emerge at radiators in heating systems. The radiators warm from the steam's heat. As the steam gives off its heat, it condenses back to liquid water and returns to the tank.
