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.
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.
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.
