2. Tankless water heating - Wikipedia

   en.wikipedia.org/wiki/Tankless_water_heating

   POU tankless heaters also can save more energy than centrally installed tankless water heaters, because no hot water is left in lengthy supply pipes after the flow is shut off. However, POU tankless water heaters are often installed in combination with a central water heater, since the former type have usually been limited to under 6 litres ...

3. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   The inside of a hydraulically operated two-stage tankless heater, heated by single phase electric power. The copper tank contains heating elements with 7.2 kW maximum power. Tankless water heaters—also called instantaneous, continuous flow, inline, flash, on-demand, or instant-on water heaters—are gaining in popularity.

4. Storage water heater - Wikipedia

   en.wikipedia.org/wiki/Storage_water_heater

   Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal.

6. Energy factor - Wikipedia

   en.wikipedia.org/wiki/Energy_factor

   The energy factor metric only applies to residential water heaters, which are currently defined by fuel, type, and input capacity. [5] Generally, the EF number represents the thermal efficiency of the water heater as a percentage, since it is an average of the ratio of the theoretical heat required to raise the temperature of water drawn to the amount of energy actually consumed by the water ...

7. Thermosiphon - Wikipedia

   en.wikipedia.org/wiki/Thermosiphon

   Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used). A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump.
