If you are currently only planning your new garden pond or have recently decided to improve your pond set-up either to achieve clearer water for aesthetic reasons or because you want to start keeping fish, you will be looking at pond pumps. These help to keep your pond moving and aerated, which is essential for an aquatic life you may have, and they also help to power things like water features and filtration systems for keeping ponds clean.
That being said, pond pumps are, in most instances, a very important and essential accessory for the majority of pond set-ups. There are obviously many considerations you will need to make when looking at the pond pumps available on the markets. Considerations such as the pump size, power rating, style and many other important aspects about the pump itself.
However, from a budgeting point of view for not just the pump itself but for your pond as a whole, the most important consideration you need to make is running cost of the pump. The running cost is obviously closely related to the pond pump electricity consumption. With the exception of perhaps solar pond pumps, pond pumps cost money to run. When you take into consideration the fact that most pumps should be run day in day out throughout the course of a year, understanding just how much money a pump is going to cost you on a daily, weekly and even yearly basis, is crucial for your budget.
Failing to factor in the cost of running the pump, could mean that your pond set-up ends up costing you more than you expected.
Have no fear though, as we have put together a quick and easy to follow guide to help you understand how you can calculate the cost of running a particular pump before buying it.
Understanding Pond Pump Wattage
As you’d probably imagine, different pumps use a different amount of electricity. The amount a particular product uses is displayed on the actual pump and is normally featured in the specifications list on the site you are looking to buy one from. The electricity is generally measured in watts.
Watts are a measurement that equates to the amount of energy converted in an hour. With regards to a pond pump, therefore, this is the average amount of electricity the pump converts into energy that it uses to push the water into the pond.
The wattage is a good indication of where on the high or low running cost scale a particular pond pump lies. The higher a pond pump’s wattage, the more expensive it will be to run that pump.
Formula For Calculating The Daily Running Cost Of Pond Pumps
There is a formula you can use to work out the running costs of a pump. You need to know a few key pieces of information to use the formula though. This includes:
- The pond pump wattage (converting it into kilowatts by dividing the number by 1000, will help)
- The cost per kilowatt/hour of electricity.
Therefore the formula is – Pond pump kW x the cost of electricity.
