Which component is not typically found in a boiler system?

In a boiler system, the primary components include the boiler itself, a boiler pump, a temperature control valve, and an expansion tank. The furnace blower is associated with furnace systems, which are designed to heat air and distribute it throughout a space. In contrast, a boiler heats water and circulates it through radiators or baseboard heaters for heating purposes.

The boiler pump is essential as it moves the heated water throughout the heating system. The temperature control valve helps regulate the temperature of the water and maintains comfort levels. The expansion tank is included to accommodate the expansion of water as it heats, preventing excessive pressure in the system. Therefore, the absence of a furnace blower in a boiler system accurately identifies it as the component not typically found in such a setup.
