One of the most recent trends in the pool-equipment industry is to go “green,” that is, to provide consumers with energy-saving devices that can do the job at a reduced cost over a period of time.

Variable-speed solar pumps have been added to the 00® family of circulators. The pumps are designed to match solar collector output, a feature that increases solar system performance by 20 percent.

In a previous article I promised that we would venture into the word of light commercial pump sizing using variable speed pumps (July, p. 36). How many times have we been called upon to work on a ...

The Evolution® Extreme variable-speed heat pump (280ANV) offers efficiencies of up to 13 HSPF and up to 20.5 SEER. When combined with an Evolution® control and Evolution® gas furnace or fan coil, the ...

The ePump + SVRS is a 2.0 horse power pump with eight variable speeds and incorporates the benefits of a Safety Vacuum Release System (SVRS). Zodiac's SVRS technology aids in the prevention of full ...

Can variable speed pumps be used on compensated heating circuits, in place of three port and pressure relief valves. Are they cost effective, and how is the pump controlled? Variable speed driven ...

THIS INTELLIGENT VARIABLE SPEED PUMP is designed for the commercial HVAC market. Variable speed technology allows the pump to automatically adjust to meet the actual system demand. The resulting ...

First note - I am a completely new to water cooling, this is the first build I've done. With GPU prices the way they are, I decided to try for an overclock vs a new GPU. Things are working well, and I ...

Chris Parsloe argues that a modular approach to system design helps exploit the energy saving potential of variable speed pumps In the shadows cast by Part L of the new Building Regulations and the ...
