Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Hydraulic power = water density × gravity × flow × total head. Input power divides hydraulic power by overall efficiency. Energy use multiplies input power by runtime.
FAQ
Water Pump Energy Cost Calculator questions
Why does more head increase energy use?+
The pump must add more energy to each unit of water as total dynamic head rises.
Does throttling change cost?+
Yes. Throttling changes the operating point on the pump curve and may reduce flow without proportional energy savings.
Can a variable-speed pump save energy?+
Often, when flow demand varies, but savings depend on the system curve and control strategy.
