Energy-efficient pond pumps are more expensive to purchase, but can be ‘earned back’ within a certain period of time. This article will explain with a number of examples why it is smart to compare the energy costs of pond pumps. After all, you can save a significant amount on the electricity bill at the end of the year.
Pond pumps
A pond pump is a device that will have to function in a koi pond (or normal pond) 24 hours a day, 365 days a year. There are many different types of pond pumps for sale. Fortunately, nowadays there are more and more manufacturers who take into account the electricity costs of the pond pumps that are produced. Yet very large differences can still be observed when these pond pumps are compared with each other.
Two examples will be used to explain why it is wise to check your pond pump for power consumption. Two pond pumps with a high capacity and two pond pumps with a high capacity will be used for this.
Cheaper pond pumps are often expensive pumps in use. How much this makes a difference will be explained in this article.
Calculation example for a low capacity pond pump
When comparing the two low capacity pond pumps, an EcoMax DM-8000 and EcoMax M-8500 model pond pump was used. Both pond pumps move +/- 8,000 liters of water per hour.
| Fashion model | EcoMax DM-8000 | EcoMax M-8500 |
|---|---|---|
| Capacity per hour | 8,000 liters | 8,200 liters |
| Power consumption | 70 Watt | 95 Watt |
| Head | Maximum 4.5 meters | Maximum 4.2 meters |
| MSRP | ?? 182.75 | ?? 116, – |
Calculation of electricity consumption per year
The following formula can be used to calculate the electricity consumption per year:
EcoMax DM-8000: 70 * 24 * 365/1000 = 613.2 kW per year
EcoMax M-8500: 95 * 24 * 365/1000 = 832.2 kW per year
Calculation of electricity costs per year
To calculate the electricity costs per year, we will have to multiply the number of kW consumed by the pond pump by the price per kW. As an average price we can ?? 0.25 handle per kW used.
EcoMax DM-8000: 613.2 kW * ?? 0.25 = ?? 153.30 per year
EcoMax M-8500: 832.2 kW * ?? 0.25 = ?? 208.05 per year
Comparison
When we make a comparison between these two pond pumps, you can immediately see how much electricity costs are saved by choosing the EcoMax DM-8000.
| Fashion model | EcoMax DM-8000 | EcoMax M-8500 |
|---|---|---|
| Electricity costs per year | ?? 153.30 | ?? 208.05 |
| Savings after 1 year | ?? 54.75 | |
| Savings after 2 years | ?? 109.5 | |
| Savings after 3 years | ?? 164.25 |
The EcoMax DM-8000 is significantly cheaper in terms of energy costs. However, since the purchase price only has an additional cost of ?? 66.75 compared to the EcoMax M-8500, it is certainly worthwhile to spend a little more money when purchasing the pond pump. The more expensive pond pump pays for itself within a little more than just one year in terms of electricity costs.
Calculation example for a high capacity pond pump
When comparing the two high-capacity pond pumps, a Blue Eco 320 and EcoMax P-25000 model pond pump was used. Both pond pumps move 25,000 liters of water per hour.
The Blue Eco is a relatively expensive pump, but this pump has a controller and the wattage and speed of the pond pump itself can be determined.
| Fashion model | Blue Eco 320 | EcoMax P-25000 |
|---|---|---|
| Capacity per hour | 25,000 liters | 25,000 liters |
| Power consumption | 320 Watt (adjustable) | 520 Watt |
| Head | Maximum 9 meters | Maximum 8 meters |
| MSRP | ?? 799, – | ?? 244.50 |
Calculation of electricity consumption per year
The following formula can be used to calculate the electricity consumption per year:
Blue Eco 320: 320 * 24 * 365/1000 = 2803.2 kW per year
EcoMax P-25000: 520 * 24 * 365/1000 = 4555.2 kW per year
Calculation of electricity costs per year
To calculate the electricity costs per year, we will have to multiply the number of kW consumed by the pond pump by the price per kW. As an average price we can ?? 0.25 handle per kW used.
Blue Eco 320: 2,803.2 kW * ?? 0.25 = ?? 700.80 per year
EcoMax P-25000: 4555.2 kW * ?? 0.25 = ?? 1138.80 per year
Comparison
When making a comparison, it can be seen how much costs can be saved per year by using the Blue Eco 320 pond pump.
| Fashion model | Blue Eco 320 | EcoMax P-25000 |
|---|---|---|
| Electricity costs per year | ?? 700.80 | ?? 1138.80 |
| Savings after 1 year | ?? 438.00 | |
| Savings after 2 years | ?? 876.00 | |
| Savings after 3 years | ?? 1314.00 |
In terms of energy costs, the Blue Eco 320 is clearly significantly cheaper. There is no less than ?? 438.00 savings in electricity costs per year. However, the pump is also considerably more expensive to purchase, the additional cost is ?? 758.50. In this way we can read that the more expensive Blue Eco will pay for itself within two years. After this you can ?? Saving 438 per year on your electricity bill.
Not to forget that the Blue Eco 320 is an adjustable pond pump. The pump has a controller with which the pump can be regulated in terms of speed and wattage. In the winter period, when it is not necessary to work at full capacity with the pond pump, the wattage can be significantly reduced.
Conclusion
Do not immediately be alarmed by expensive pond pumps. Do not rely directly on the “bargains” or cheaper pond pumps. Cheap is often expensive for this equipment. Be careful when choosing a pond pump, always calculate the energy costs per year. Base the choice of the pond pump on, among other things, the calculation.
