1. Submersible Pumps: Submersible pumps are placed directly into the well and are typically more energy-efficient than above-ground pumps. They use about 1 to 1.5 kilowatts (kW) of electricity per hour.
2. Above-Ground Pumps: Above-ground pumps, also known as jet pumps, are installed outside the well and use a suction line to draw water from the well. They generally consume around 1.5 to 2.5 kW of electricity per hour.
3. Well Depth: The deeper the well, the more electricity the pump will need to lift water to the surface. For every 10 feet of well depth, the pump's power consumption increases by about 10%.
4. Water Pressure: The higher the water pressure required, the more electricity the pump will use. Each 1 psi (pound per square inch) increase in pressure adds about 10% to the pump's energy consumption.
5. Frequency of Use: The more frequently the pump is used, the more electricity it will consume. If your pump runs for several hours each day, it will use more electricity than if it only runs for a few minutes per day.
On average, a typical household well pump uses about 1,000 to 2,000 kilowatt-hours (kWh) of electricity per year. However, this can vary significantly depending on the factors mentioned above. To get a more accurate estimate of your well pump's electricity usage, consult with a qualified electrician or plumber.
