2. Swimming pool - Wikipedia

   en.wikipedia.org/wiki/Swimming_pool

   A swimming pool, swimming bath, wading pool, paddling pool, or simply pool, is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground (in-ground pools) or built above ground (as a freestanding construction or as part of a building or other larger structure), and may be found as a ...

3. Ground source heat pump - Wikipedia

   en.wikipedia.org/wiki/Ground_source_heat_pump

   These heat pumps are also preferred for pool heating. Heat pumps typically only heat water to about 55 °C (131 °F) efficiently, whereas boilers typically operate at 65–95 °C (149–203 °F) [citation needed]. The size of radiators designed for the higher temperatures achieved by boilers may be too small for use with heat pumps, requiring ...

4. Specific pump power - Wikipedia

   en.wikipedia.org/wiki/Specific_pump_power

   Specific Pump Power (SPP) is a metric in fluid dynamics that quantifies the energy-efficiency of pump systems. It is a measure of the electric power that is needed to operate a pump (or collection of pumps), relative to the volume flow rate. It is not constant for a given pump, but changes with both flow rate and pump pressure.

   However, the earth can be used to partially cool and dehumidify the replacement fresh air intake for passive-solar thermal buffer zone [5] areas like the laundry room, or a solarium / greenhouse, especially those with a hot tub, swim spa, or indoor swimming pool, where warm humid air is exhausted in the summer, and a supply of cooler drier ...

6. High efficiency glandless circulating pump - Wikipedia

   en.wikipedia.org/wiki/High_efficiency_glandless...

   Many minor factors of the pump's design including its double pump system and control options give it additional efficiency without sacrificing any of its performance. By using a double pump system together with variable and automatic control, the pump is able to decrease its energy consumption while increasing efficiency and reliability. [7]
