  2. Circulator pump - Wikipedia

    en.wikipedia.org/wiki/Circulator_pump

    A circulator pump for home use. A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit with small elevation changes. They are commonly found circulating water in a hydronic heating or cooling system.

  3. Forced circulation boiler - Wikipedia

    en.wikipedia.org/wiki/Forced_circulation_boiler

    The forced circulation boiler begins the same as a natural circulation boiler, at the feed water pump. Water is introduced into the steam drum and is circulated around the boiler, leaving only as steam. What makes the forced circulation boiler different is its use of a secondary pump that circulates water through the boiler. The secondary pump ...

  4. Powerhead (pump) - Wikipedia

    en.wikipedia.org/wiki/Powerhead_(pump)

    A switching or variable-voltage system (also known as a "wavemaker") is commonly used in reef aquaria to more closely simulate the movement of ocean water. [1] Water circulation is vital to proper biological filtration of most saltwater aquaria (particularly those using the Berlin Method), and is useful in freshwater aquaria for allowing free ...

  5. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    Circulating hot water can be used for central heating. Sometimes these systems are called hydronic heating systems. [22] Common components of a central heating system using water-circulation include: A supply of fuel, electric power or district heating supply lines; A boiler (or a heat exchanger for district heating) which heats water in the system

  6. Hydronics - Wikipedia

    en.wikipedia.org/wiki/Hydronics

    Hydronics (from Ancient Greek hydro- 'water') is the use of liquid water or gaseous water or a water solution (usually glycol with water) as a heat-transfer medium in heating and cooling systems. [ 1 ] [ 2 ] The name differentiates such systems from oil and refrigerant systems.

  7. Boiler feedwater pump - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater_pump

    A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler. The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler. These pumps are normally high pressure units that take suction from a condensate return system and can be of the ...

  8. Condensate pump - Wikipedia

    en.wikipedia.org/wiki/Condensate_pump

    This pump and possibly many more around the plant returns this hot water back to a make-up tank closer to the boiler, where it can be reclaimed, chemically treated, and reused, in the boiler, consequently it can sometimes be referred to as a condensate return pump.

  9. Water-tube boiler - Wikipedia

    en.wikipedia.org/wiki/Water-tube_boiler

    A high pressure watertube boiler [1] (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by fire. Fuel is burned inside the furnace , creating hot gas which boils water in the steam-generating tubes.
