Which component is distributed by the boiler to the building's heating system?

• A. Steam or hot water
• B. Electricity
• C. Cold water
• D. Air

Answer: (A)

The boiler’s job is to create heat in a fluid and push that heated fluid through the building’s distribution network. Whether it generates steam or heats water, that medium—steam or hot water—is what travels through pipes to radiators, baseboards, or heating coils to deliver warmth to spaces. Electricity, while essential to the building’s systems, is distributed by the electrical system, not by the boiler. Cold water may be the feed to the boiler, but it isn’t the heated medium distributed to heat the building. Air is moved by the HVAC air distribution system, not the boiler.
