Well Pump Electrical Usage

Dedicated circuit for well pumps.

Well pump electrical usage. The amount of energy required is a function of the amount of water consumed by the household. A breaker that keeps tripping likely means a problem with the well pump and you ll need to call a pro for that. To do this work the pump converts electricity into mechanical action and the harder the job the more electricity it uses. To calculate electrical energy for well pumps we first calculate the energy needed to lift and pressurize the water for delivery to the home then divide by the overall efficiency of the pump and motor system wateright 2003 and greenberg 2005.

The pump basically is recirculating the water back into the well. You could pump 1000 gallons for a kwh of power. Whatever the type of pump it does the same thing which is lifting water from the well to ground level. Take the wattage of the specific water pump and multiply it times how many hours a day it runs.

Be sure the power is on. Submersible pumps with iron pipe to the wellhead that use a below frostline casing fitting have an o ring in the slider coupling assembly that can rot and cause a leak back into the well. If you have a 100 ft deep well and if you want to pressurize your water to a bare minimum of 30 psi ie another 69 ft of lifting each gallon of water you pump will require almost exactly 1 watt hour of power assuming the 55 efficiency. 120 volt power for a pump house light and heat cable.

You will then multiply the three power consumption operating hours cost of electricity together to calculate total cost per. Are they in the pump house or at the. Start by checking that the well switch located near your pressure tank hasn t been switched off. The circuit to the well pump is a dedicated circuit designed for the load of the well pump only.

Not sure where the main water shutoff valves are. Then check the well s double pole circuit breaker to see that it hasn t tripped. Then multiply it by how many days a year it runs and divide by 1000. Electrically powered well pumps may be submersible or positioned clear of the water.

The average cost is 0 12 per kilowatt hour. A typical water pump s wattage can vary between 250 watts to 1 100 watts. There is a calculation to find the power consumption of a water pump. The 240 volt pump circuit to your well pump does not have a neutral so you cannot get 120 volts without doing something that would be unsafe.
