2. Circulator pump - Wikipedia

   en.wikipedia.org/wiki/Circulator_pump

   By installing a thermostatically controlled pump just after the farthest fixture on the loop, cyclic pumping maintains ready hot water up to the last fixture on the loop instead of wasting energy heating the piping from the last fixture to the water heater. Installing a circulation pump at the farthest fixture on a hot water circulation loop is ...

3. Water heat recycling - Wikipedia

   en.wikipedia.org/wiki/Water_heat_recycling

   Installation of a double-walled copper-on-copper heat exchanger in a vertical section of the master drain line in a Canadian home (2007) Water heat recycling (also known as drain water heat recovery, waste water heat recovery, greywater heat recovery, [citation needed] or sometimes shower water heat recovery [citation needed]) is the use of a heat exchanger to recover energy and reuse heat ...

4. Thermosiphon - Wikipedia

   en.wikipedia.org/wiki/Thermosiphon

   Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used). A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump.

5. Soil regeneration - Wikipedia

   en.wikipedia.org/wiki/Soil_regeneration

   Soil regeneration, as a particular form of ecological regeneration within the field of restoration ecology, is creating new soil and rejuvenating soil health by: minimizing the loss of topsoil, retaining more carbon than is depleted, boosting biodiversity, and maintaining proper water and nutrient cycling. [1]

6. Circulation evaporator - Wikipedia

   en.wikipedia.org/wiki/Circulation_evaporator

   Tubular forced circulation evaporators employs an axial circulation pump which navigates the flow of liquid in a circular motion through the system's heat exchanger in which it is superheated. Thereafter, when the liquid reaches the separator the liquid pressure decreases dramatically forcing a portion of the liquid to be rapidly boiled off.

7. High-density solids pump - Wikipedia

   en.wikipedia.org/wiki/High-density_solids_pump

   Reciprocating pumps include plunger, diaphragm, and piston pumps. The high-density solids pumps which can be used in the widest range of situations are piston (or reciprocating) pumps. They can be realized as single-cylinder or two-cylinder pumps. In the latter case, power is transferred to the material via delivery pistons working in push-pull ...

8. Forced circulation boiler - Wikipedia

   en.wikipedia.org/wiki/Forced_circulation_boiler

   The secondary pump takes the feed water going to the boiler and raises the pressure of the water going in. In a natural circulation boilers, the circulation of water is dependent on the differential pressures caused by the change of density in the water as it is heated. That is to say that as the water is heated and starts turning to steam, the ...

9. 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 ...
