How much does it cost to run different sized pumps?

Different types and sizes of pumps will have different sized motors, which will affect how much they cost to run. It’s possible to work out a rough idea of the total cost per annum of running the pump with a simple calculation that will help you forecast costs for the coming year.

For example, a pump with a motor size of 1.1Kw running 24/7 365 days per year will require 9,636kw per annum. At an average cost per kWh of 10p, the total cost per annum will be £963.60.

Calculation:

1.1 (Pump motor size in kW) x 24 (hours) x 365 (days) = 9636 kW per annum.

£0.10 (Cost per kWh) x 96336 (kW per annum) = £963.60 total cost per annum.

You can even adjust this calculation by the number of hours a pump runs in a day and how many days it runs in a year. For example, if we take the previous example but with the pump only running for 8 hours during weekdays, the total cost per annum would be £229.68.

Calculation:

Pump motor size in kW x 8 (hours) x 261 (days) = 2296.8 kW per annum.

£0.10 (Cost per kWh) x 2296.8 (kW per annum) = £229.68 total cost per annum.

Here are the costs for different size pumps running 24/7 365 days per year:

5.5 kW – £4,818

11 kW – £9,636

18.5 kW – £16,206

22 Kw – £19,272

30 kW – £26,280

90 kW – £78,840

If you want to work out the potential cost per annum of your pump, simply use this calculation.

Size of pump motor in Kw x hours pump runs per day x number of days in the year the pump will be running = Number of kW per annum.

The number of kW per annum x cost per kWh = Total cost per annum.

As you can see, the costs can start to rack up if you have a large pump running constantly, and the costs can be even higher if your pump systems are inefficient and are using more energy than is required.
