Which of the following is a precaution when installing electric storage heaters?

• A. The heater is securely fixed to a wall with suitable wall-fixing screws
• B. The heater should be placed on carpet for insulation
• C. The heater should be placed on a metal frame
• D. The heater's location should block vents

Answer: (A)

Secure mounting to a wall with suitable wall-fixing screws is essential because electric storage heaters are heavy and generate heat over a large surface. When they’re firmly fixed, they won’t tip or shift, which reduces the risk of injury or fire and ensures proper clearance for airflow and maintenance. Using the correct fixings for the wall type (masonry or timber) and following manufacturer guidance helps maintain structural integrity and safe operation.

Placing the heater on carpet isn’t safe because it can be a fire risk and provides unstable support for a heavy appliance, potentially blocking heat dissipation. A metal frame isn’t ideal either, since it may not offer the required stability or clearance and could still allow tipping. Blocking vents is dangerous because it restricts airflow, leading to overheating and reduced efficiency.
