Electric Storage Heaters: Operation and Maintenance

Principles of Operation

Electric storage heaters, such as those manufactured by Creda, function by accumulating heat during off-peak electricity periods and releasing it later. They typically utilize bricks or other high-heat-capacity materials to store thermal energy. These materials are heated by internal electric resistance elements. The stored heat is then gradually released through natural convection or via a fan, depending on the model. Thermostatic controls regulate the heating and release of stored heat to maintain a desired temperature.

Control Mechanisms

Most models incorporate a thermostat to regulate the internal temperature. This thermostat determines the amount of heat released to the room. Many units also have input controls to adjust the desired temperature, which influences the rate of heat release. Some models feature timers allowing for pre-programmed heating schedules, optimizing energy consumption by only heating during required periods.

Types of Controls

• Mechanical Controls: These often involve rotary dials or switches for temperature and timing adjustments.
• Digital Controls: Digital displays and buttons provide precise temperature settings and programmable timers for greater control.

Safety Features

Safety features vary by model but often include overheat protection mechanisms that automatically shut down the heater if it reaches dangerously high temperatures. Regular inspection for any damage to the unit's casing or wiring is crucial for continued safe operation.

Maintenance

Regular cleaning is essential to ensure efficient operation. Dust accumulation can reduce the heater's ability to both store and release heat. Consult the manufacturer's instructions for specific cleaning recommendations. It's important to regularly check the unit for any signs of damage or malfunction, contacting a qualified electrician if necessary.

Energy Efficiency

Optimizing the use of the timer and thermostat can significantly improve energy efficiency. Avoiding unnecessary heating periods and setting the thermostat to an appropriate level minimizes energy consumption. Consider using insulation and draught excluders to maintain the desired room temperature with less reliance on the heater.
