  7. Heat trap - Wikipedia

    en.wikipedia.org/wiki/Heat_trap

    Heat traps are valves or loops of pipe on the cold water inlet and hot water outlet of water heaters. The heat traps allow cold water to flow into the water heater tank, but prevent unwanted natural convection and heated water to flow out of the tank. [1] [2] Newer water heaters have built-in heat traps.

  8. Shower-curtain effect - Wikipedia

    en.wikipedia.org/wiki/Shower-curtain_effect

    Hanging the weight low against the curtain just above the rim of the shower pan or tub makes it an effective billowing deterrent without allowing the weight to hit the pan or tub and damage it. There are a few alternative solutions that either attach to the shower curtain directly, attach to the shower rod or attach to the wall.

    In the tropics, this may occur, for example if a clothes drier has not been used for a year or a large water boiler used for coffee, etc. has been in storage. In such cases, if the unit is allowed to power up without RCD protection then it will normally dry out and successfully pass inspection.
