In a fan assisted night storage heater, where is the fan circuit connected?

• A. General domestic supply
• B. Restricted off-peak supply
• C. Battery pack
• D. Solar panel

Answer: (A)

The fan is used to push warm air from the stored heat out into the room, so it needs to be powered from the regular mains whenever heat is being distributed. Connecting the fan to the general domestic (main) supply lets it run during the day when the stored heat is being released, independent of the off-peak charging cycle. The off-peak (restricted) supply is reserved for charging the storage elements at night, not for driving the fan. Battery packs or solar panels aren’t part of the standard fan circuit for a night storage heater either.
