2. Expansion tank - Wikipedia

   en.wikipedia.org/wiki/Expansion_tank

   Expansion tank in a central heating system. 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 ...

3. Steam accumulator - Wikipedia

   en.wikipedia.org/wiki/Steam_accumulator

   A steam accumulator is an insulated steel pressure tank containing hot water and steam under pressure. It is a type of energy storage device. It can be used to smooth out peaks and troughs in demand for steam. Steam accumulators may take on a significance for energy storage in solar thermal energy projects.

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. Pressure tank - Wikipedia

   en.wikipedia.org/wiki/Pressure_tank

   The diaphragm or bladder may itself exert a pressure on the water, but it is usually small and will be neglected in the following discussion. Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V. Referring ...

6. Boiler blowdown - Wikipedia

   en.wikipedia.org/wiki/Boiler_blowdown

   The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of showering hot water on nearby individuals.

7. 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 ...

8. Boiler - Wikipedia

   en.wikipedia.org/wiki/Boiler

   Trycock: a type of valve that is often used to manually check a liquid level in a tank. Most commonly found on a water boiler. Flash tank: High-pressure blowdown enters this vessel where the steam can 'flash' safely and be used in a low-pressure system or be vented to atmosphere while the ambient pressure blowdown flows to drain.

9. Pressure vessel - Wikipedia

   en.wikipedia.org/wiki/Pressure_vessel

   The ASME definition of a pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. [2]The Australian and New Zealand standard "AS/NZS 1200:2000 Pressure equipment" defines a pressure vessel as a vessel subject to internal or external pressure, including connected components and accessories up to the connection to external ...
