What material stores heat in night storage heaters and what precaution is taken when mounting these?

• A. Heat stored in fire clay blocks; heavy; caution when handling
• B. Water-filled blocks; float
• C. Plastic pellets; light
• D. Copper bricks; brittle

Answer: (A)

Night storage heaters use fire-clay blocks to store heat. These blocks are dense and heavy, which lets the heater absorb heat during the night and release it gradually during the day. Because of their weight, mounting requires careful handling and solid, proper fixings. Make sure the mounting surface can support the load, use anchors rated for heavy fixtures, and handle the blocks with care to avoid damage or injury. The other materials listed don’t match how night storage heaters store heat, and their properties wouldn’t apply to this type of setup.
