Pond Pumps Vs Pool Pumps
Often people install pool pumps to run their water feature because of initial cost savings of purchasing such a pump. This is ill-advised for a variety of reasons; most importantly, use of a pool pump can lead to massive increases in your electricity bill.
Also, many unscrupulous landscapers and some retailers provide quotations that include supply of a pool pump rather than a pond pump in order to reduce final cost of quotation in an effort to win work. They do not inform recipient of quotation of running costs of a pool pump.
Simple arithmetic proves that initial cost savings of purchasing a pool pump to run your water feature can cause a blow out of staggering proportions in your annual budget. This is especially true when keeping fish or plants, which requires that your pump is running 24 hours a day to oxygenate water.
To calculate your operating costs per year multiply watts your pump uses per hour, by number of hours you run it per year (if you run it 24/7 then use 8,760 hours per year), then divide by 1,000 to convert it to kilowatts, then multiply by your cost per kWh (kilowatt-hour) ($0.1447 in QLD – see www.energexinstitute.com).
watts x 8,760 / 1,000 x $kWh = $ operating costs per year
A Blagdon Amphibious P8000 Fountain Pump (169 watt)
169 (watt) x 8760 (hours per year) / 1000 x $0.1447 = $214.22 per year
An Average 1.0 HP Pool Pump (750 watt)
750 (watt) x 8760 (hours per year) / 1000 x $0.1447 = $950.68 per year
Total Cost Savings = $736.46 per year ($184.12 every quarter!)
