In a night storage heating system, which device is used to regulate the room temperature?

• A. Room stat
• B. Thermal cutout
• C. Charge controller
• D. Fan

Answer: (A)

Controlling how warm a room gets comes from a device that senses the room air temperature and turns the heat source on and off to keep the room at the chosen temperature. In a night storage heater, the bricks store heat overnight and release it during the day. The room stat sits in the living space, monitors the air temperature, and signals the heater to release stored heat when the room cools to the setpoint, and to stop heating once the setpoint is reached. This keeps the room at a comfortable level without wasting energy. The other devices serve different roles: a thermal cutout is a safety device that cuts power if the system overheats, not for maintaining a temperature setpoint. A charge controller relates to charging batteries or storage in solar/battery systems, not typical room-heat regulation. A fan helps circulate air but does not control how much heat is produced.
