    This type of water heater could be 24% to 34% more energy-efficient than a traditional water heater, according to the Department of Energy. Tankless water heaters can also save space, as they don ...

  3. Internal combustion engine cooling - Wikipedia

    en.wikipedia.org/wiki/Internal_combustion_engine...

    For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and ...

  4. Condensate polisher - Wikipedia

    en.wikipedia.org/wiki/Condensate_polisher

    Condensate polishers are important in systems using the boiling and condensing of water to transport or transform thermal energy.Using technology similar to a water softener, trace amounts of minerals or other contamination are removed from the system before such contamination becomes concentrated enough to cause problems by depositing minerals inside pipes, or within precision-engineered ...

  5. Antifreeze - Wikipedia

    en.wikipedia.org/wiki/Antifreeze

    Proper engine coolant and a pressurized coolant system obviate these shortcomings of water. With proper antifreeze, a wide temperature range can be tolerated by the engine coolant, such as −34 °F (−37 °C) to +265 °F (129 °C) for 50% (by volume) propylene glycol diluted with distilled water and a 15 psi pressurized coolant system.

  6. Water cooling - Wikipedia

    en.wikipedia.org/wiki/Water_cooling

    Water is inexpensive, non-toxic, and available over most of the earth's surface.Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer.

  7. Heat pipe - Wikipedia

    en.wikipedia.org/wiki/Heat_pipe

    In a heat pipe life test, heat pipes are operated for long periods of time, and monitored for problems such as non-condensable gas generation, material transport, and corrosion. [17] [18] The most commonly used envelope (and wick)/fluid pairs include: [19] Copper envelope with water working fluid for electronics cooling. This is by far the most ...

  8. Automatic bleeding valve - Wikipedia

    en.wikipedia.org/wiki/Automatic_bleeding_valve

    The top has a small outlet, usually hidden beneath a plastic dust cap. Internally there is a large hollow body, normally filled with water, and containing a float valve. The valve must always be installed vertically, usually at the top of a short vertical pipe. If the valve body is filled with water, the float moves upwards and closes the valve.

  9. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    The presence of certain metal ions like calcium and magnesium, principally as bicarbonates, chlorides, and sulfates, in water causes a variety of problems. [1] Hard water leads to the buildup of limescale, which can foul plumbing, and promote galvanic corrosion. [2] In industrial scale water softening plants, the effluent flow from the re ...
