In a fan-assisted night storage heater, what feature boosts daytime heat output?

• A. External blower boosts daytime output
• B. Internal fan boosts daytime output, controlled by switch or room thermostat
• C. The heater only uses stored heat at night
• D. The fan reduces heat output

Answer: (B)

The feature that boosts daytime heat output in a fan-assisted night storage heater is an internal fan that circulates the stored heat more quickly into the room. This fan is often controlled by a boost switch or the room thermostat, so you can increase the rate of heat delivery when more warmth is needed. The heater stores heat overnight and releases it during the day; the fan simply speeds up how fast that stored heat is distributed, making the room feel warmer without creating extra energy.
