    Inside the boiler, the burners or electric coils generate heat that is transferred to the water by the heat exchanger. The process creates either hot water or steam, depending on the type of boiler. The hot water or steam is circulated via pipes throughout your commercial facility. The water or steam enters radiators or other components that disperse the heat providing the heating you need to keep your indoor spaces comfortable. Natural gas is the most common fuel used in commercial boilers.Learn More
