2. 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.

3. Hot water storage tank - Wikipedia

   en.wikipedia.org/wiki/Hot_water_storage_tank

   A hot water storage tank (also called a hot water tank, thermal storage tank, hot water thermal storage unit, heat storage tank, hot water cylinder, and geyser) is a water tank used for storing hot water for space heating or domestic use. Water is a convenient heat storage medium because it has a high specific heat capacity. This means ...

4. Expansion tank - Wikipedia

   en.wikipedia.org/wiki/Expansion_tank

   An expansion tank or expansion vessel is a small tank used to protect closed water heating systems and domestic hot water systems from excessive pressure. The tank is partially filled with air, whose compressibility cushions shock caused by water hammer [citation needed] and absorbs excess water pressure caused by thermal expansion. [1]

7. Central vacuum cleaner - Wikipedia

   en.wikipedia.org/wiki/Central_vacuum_cleaner

   This datum is calculated as follows: P = 1/8.5 x F x S where P translates to the power in air watts; F is the airflow in CFM; and S for the water lift in inches. The standard air watt formula is from ASTM International (see document ASTM F558-21). [3] The air watts indicate the motor's global performance, and thus the central vacuum's ...
