How Many Watts Does A Well Pump Use

How many watts a well pump uses depends on the type of pump, the depth of the well, and the amount of water being pumped. In general, a well pump uses between The average power rating of a well pump is about 700 to 800 watts. However, some pumps can use as much as 5,000 watts.

How many watts a well pump use depends on many factors; which horsepower is the most important player? It also depends on how old is your system, the time a well pump works a day, and how much water you are pumping.

Key Takeaways About Well Pump Wattage

  1. How many watts does a well pump use? An average well pump uses about 700 to 800 watts of electricity; however, the larger pumps can go up to 2000 to 5000 watts.
  2. Using a well pump for 8 hours a day will consume 6.4 kilowatt-hours a day and 44.8 kilowatt-hours a week.
  3. Solar power generators are a great choice for running well pumps as they are cost-effective because they are zero fuel cost and can work in off-grid setups.

How Many Watts Does A Well Pump Use?

How many watts a well pump use is an important question because well pumps consume a considerable amount of power and thus can increase your electricity bill drastically. It is also possible that some areas may have cheaper electricity tariffs during certain hours. So running your well pump at off-peak hours can save you money.  

Let us analyze the well pump power consumption in detail. Also, note that you will mostly find the well pump rating in horsepower instead of watts. One horsepower is equal to approximately 746 watts. You find the well pump motor size on the pump level.

Definition of Volts, Watts, Amps, and kWh

We need some background knowledge to understand how many watts a well pump uses. We need to know a few terms, i.e., volts, amperes, watts, horsepower, etc. So, here are the basic definitions.

Volts (V): Voltage is the speed of electric current passing through an electric circuit. It is measured in volts.

Amps (A): amps measure the electric current flowing through the circuit. It is short for Amperes.

Watts (W): Wattage or watts is a device's energy consumption unit.

Horsepower(HP): a horsepower is also a power unit, defined as 746 watts.

Kilowatt-hours (kWh): kilowatt-hours is the energy consumption over a period of time.

How Many Watts Does A Well Pump Use?

Well, pumps are available in a range of sizes and power consumption. The smaller well pumps can consume 400 to 500 watts. The larger ones can go from 2000 to 5000 watts. However, the average well pump size is 700 to 800 watts. An average well pump will use 5.6 to 6.4 kilowatts for 8 hours.

What Size Generator Do I Need for Well Pump When Off-Grid?

It is evident that well pump use medium to high amounts of energy. So running them can be expensive. Also, when you decide to go off-grid, you need an alternative power supply for your well pump.

Solar generators are the best solution as they are very cost-effective because of no fuel cost. However, it is important to know that the starting watts of a well pump can be higher than the running watts. The running watts are your well pump's power requirement when operating. In comparison, the starting watts are the peak power that the device needs for a while when it starts. It is required for a few minutes only.

The Jackery solar generators are available in various sizes and power ratings. You can use the Jackery solar generator 1000 Pro, 1500 Pro,  or 2000 Pro, depending on how many watts your well pump use.
