Aquavar Energy Calculator

Use this tool to approximate energy savings with an Aquavar Controller compared to a full speed pump.
Enter data in all Green Boxes.
Program assumes pumped liquid is water.
Enter up to five common flow rates required by your system, starting with the highest flow.
For each flow, enter the TDH of a full speed pump at that flow rate.
For each flow, enter the percentage of total time the pump runs at this flow.
For multi-pump systems, apply the percentage of full capacity to the flow rate of the first pump



TDH Input values Feet PSI
Flow Rates
GPM		 TDH at Max.
Speed in FEET		 % of
total time
PSI Enter the pressure to be maintained in PSI.
PSI Enter suction pressure if any in PSI.
GPM Enter the flow on the full speed pump curve
at FEET TDH
EFF Enter the efficiency of the pump at
FEET TDH & GPM
Energy Cost Enter your average energy cost per kilowatt hour.
Number of Pumps Enter number of pumps in system
 

Based on the data supplied, an Aquavar equipped pump will save:

Kilowatt Hours per year for full speed pump:71,166.70
Dollars per year for full speed pump: $7,116.67
Kilowatt Hours per year for Aquavar pump:55,145.08
Dollars per year for Aquavar pump: $5,514.51
Annual energy savings with Aquavar:$1,602.16
Annual Aquavar savings for system:$1,602.16
