  2. Water heating - Wikipedia

    en.wikipedia.org/wiki/Water_heating

    Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers. These metal vessels that heat a batch of water do not produce a continual supply of heated water at a preset temperature. Rarely, hot water occurs naturally, usually from natural hot springs. The temperature varies with the ...

  3. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    A hybrid water heater is a water heating system that integrates technology traits from both the tank-type water heaters and the tankless water heaters. [5] It maintains water pressure and consistent supply of hot water across multiple hot water applications, and like its tankless cousins, it is efficient and can supply a continuous flow of hot ...

    Japanese Zojirushi brand "Thermo Pot" electric kettle hot water dispenser Wall mounted, unpressurized electric boiler with 5 liters maximum capacity. An electric water boiler, also called a thermo pot or tea urn [1] in British English, is a consumer electronics small appliance used for boiling water [2] [3] and maintaining it at a constant temperature in an enclosed reservoir.

  5. Solar water heating - Wikipedia

    en.wikipedia.org/wiki/Solar_water_heating

    The tested SWH system had about 20% of the impact of an electrical water heater and half that of a gas water heater. [ 51 ] Analysing their lower impact retrofit freeze-tolerant solar water heating system, Allen et al. (qv) reported a production CO 2 impact of 337 kg, which is around half the environmental impact reported in the Ardente et al ...

  6. Chip heater - Wikipedia

    en.wikipedia.org/wiki/Chip_heater

    The chip heater is a single point, tankless, domestic hot water system popular in Australia and New Zealand from the 1880s until the 1960s. Examples of this form of domestic water heater are still in use. The chip heater consisted of a cylindrical unit with a fire box and flue, through which a water pipe was run. Water was drawn from a cold ...

  7. Infrared heater - Wikipedia

    en.wikipedia.org/wiki/Infrared_heater

    For example, the absorption spectrum for water has its peak at around 3 μm. This means that emission from medium-wave or carbon infrared heaters is much better absorbed by water and water-based coatings than NIR or short-wave infrared radiation. The same is true for many plastics like PVC or polyethylene. Their peak absorption is around 3.5 ...

  8. Feedwater heater - Wikipedia

    en.wikipedia.org/wiki/Feedwater_heater

    A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. [1] [2] [3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system ...
