2. Tankless water heating - Wikipedia

   en.wikipedia.org/wiki/Tankless_water_heating

   In theory, tankless heaters can always be somewhat more efficient than storage tank water heaters. In both kinds of installation (centralized and POU), the absence of a tank saves energy compared to conventional tank-type water heaters, which have to reheat the water in the tank as it cools off while waiting for use (this is called "standby loss").

3. 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.

4. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   An 80 US gal (300 L; 67 imp gal) electric storage tank water heater was able to have a minimum energy factor of 86% under the pre-2015 standard, while under the 2015 standard, the minimum energy factor for an 80-gallon electric storage tank water heater is now 197%, which is only possible with heat pump technology. This rating measures ...

5. Hot water storage tank - Wikipedia

   en.wikipedia.org/wiki/Hot_water_storage_tank

   Two red paralleled hot water storage tanks connected to a wood-fuelled furnace. A hot water storage tank where one of the heat sources is solar heating A, that is sent into the hot water storage tank via a smaller pump B (circle with triangle) and the heat exchanger spiral in the hot water storage tank. The other spiral C can be used for a e.g ...

6. Standing loss - Wikipedia

   en.wikipedia.org/wiki/Standing_loss

   A hot water storage tank, for example, will have a standing loss of heat; a proportion of the heat generated for consumption is lost through the cylinder walls by heat transfer, and useful heat provided to the end use (e.g., a hot water tap) is reduced. Standing losses are also associated with any pipework distribution system that is employed ...

7. Combined storage tanks - Wikipedia

   en.wikipedia.org/wiki/Combined_storage_tanks

   These storage tanks are mostly insulated on the outside and designed for the lowest possible heat losses. Usually, it is a tank-in-tank system, that is, a two-compartment system arranged one inside the other. It is thus a combined buffer storage tank with a heat exchange plate in between. Above is a smaller interior tank for drinking water, i.e ...
