Heat traps are valves or loops of pipe on the cold water inlet and hot water outlet of water heaters.

[1] [2] Newer water heaters have built-in heat traps.
A hard candy (American English), or boiled sweet (British English), is a sugar candy prepared from one or more sugar-based syrups that is heated to a temperature of 160 °C (320 °F) to make candy.

Limescale is a hard, chalky deposit, consisting mainly of calcium carbonate (CaCO 3). It often builds up inside kettles, boilers, and pipework, especially that for hot water.

Rinse frequently with clean water to remove loosened dirt and eraser residue. Continue working in sections until all grout is clean. Wipe the entire area with a clean, damp cloth to remove any ...
Limescale build-up inside a pipe reduces both liquid flow and thermal conduction from the pipe, so will reduce thermal efficiency when used as a heat exchanger.. A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles.
