VARIABLE SPEED PUMP
WHY VARIABLE SPEED PUMPS?
A New Department of Energy Rule effective July 2021, Eliminates many single Or two speed pool pumps. Pumps fro, 1 HP though 5Hp must be replaced with VARIABLE SPEED PUMPS. Pumps less than ½ HP will be legal. The new variable speed pumps will be given a weighted energy factor or WEF. This factor is a measure of gallons per watt hour. The higher the gallons per watt hour the more efficient the pump. Total dynamic head of the system is a large factor in considering a new pump or motor replacement. TDH measurements need to be taken with the skimmer off, the filter clean, and pressure side valves in the open position. The system TDH can be determined at the pump drain plugs with a vacuum gauge at the suction side strainer plug and a pressure gauge at the volute drain plug. Vacuum reading X 1.13, pressure reading X 2.31=TOTAL=TDH or measure with flow meter accurate to +- 10% and installed to manufacturers specifications. Compare the TDH to manufacturer pump curve to determine flow rate for suction outlets and piping. New and replacement pumps must have GFCI protection.
BENEFITS OF VARIABLE SPEED PUMPS
- THEY SAVE A LOT OF ENERGY: They save you a lot of money. You are able to run the pump at a lot less RPM’S and because of that you save a lot of watts(power) each day. This is what yields your power savings each month. You can save up to 90% of the energy your currently using to power your pool pump!
- THEY WILL LAST LONGER: This Weill save you a lot of money. With single speed pumps costing anywhere from $600-$800 to install every 3-5 years we can help reduce how many times you need to install a pump. Wear and tear is the reason behind this. The single speed pump running at 3450 RPM is running full speed all day long for up to 12 hours a day. With a variable speed pool pump we can reduce the strain on the motor in RPMS by 40-60%.
- YOUR POOL AND EQUIPMENT WILL LAST LONGER: Your pool water will be circulating a lot more so it will be able to eliminate things like bacteria or other contaminants’s easier because the water is moving. The water will be moving slower through your filter and heater allowing both to optimally functional. This is particularly true for solar heating options.
- Can be a safety device: Because the water is running at a much lower speed the chances of entrapment are diminished greatly. Not to say this can’t happen but if you are running the pump 40-60% less power wise, it may save a life on that alone. Second, there are pumps that have a SVRS (suction release vacuum system) built in. If the pump senses an obstruction, like someone stuck to a drain or vac line, it shuts off in two seconds. I really like the PENTAIR, INTELLIFLO VS + VSRS pump which offers great money savings plus high safety.
