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

   A forced circulation boiler is a boiler where a pump is used to circulate water inside the boiler. This differs from a natural circulation boiler which relies on current density to circulate water inside the boiler. In some forced circulation boilers, the water is circulated at twenty times the rate of evaporation. [1]

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. 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 ...

6. Condensing boiler - Wikipedia

   en.wikipedia.org/wiki/Condensing_boiler

   Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.

7. Circulation evaporator - Wikipedia

   en.wikipedia.org/wiki/Circulation_evaporator

   The evaporator uses separate parts to create the overall system; a heat exchanger, separation tank and for the forced circulation system (as opposed to the natural circulation system) a circulation pump are standard although can be subject to change depending on the liquids properties of the mixtures being separated and specific design.

8. 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.

9. 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 ...
