Pool Pumps commonly use a lot of energy. Typical Pool Pumps use around 2250 watts, but the exact amount varies based on brand, size and other factors. One finds this info about power usually in the manual or right on the device itself.
A Pool Pump can rank as the second biggest energy user in the house just after the air conditioner or heat Pump. It maybe uses some thousands of kilowatt hours during a year, what can cost even 270 dollars on the yearly bill.
How Much Electricity Do Pool Pumps Use and How to Save Money
The average cost to run Pool Pumps sits between 30 and 150 dollars per month. This range relates to the kind of Pump, its size and the length of use. Local prices for electricity also matter a lot.
If you run a big Pump at high speed all day, it can add 150 to 200 dollars to the monthly cost of electricity. A small Pump at low speed adds only 30 to 40 dollars.
Single-speed Pumps use 1800 to 2500 watts when they run. These models usually cost 40 to 150 dollars monthly for electricty. For instance, an old single-speed Pump with one horsepower used 1776 watts and worked 16 hours daily during the whole year.
That adds up quickly.
Here is where the situation becomes really interesting. Switching from a standard Pump of 2000 watts to a variable-speed model of 300 watts, one can cut the energy use by around 80 percent. Every half of drop in the RPM speed cuts the energy use by almost an eighth.
Because of that, running the Pump at 1800 RPM instead of 3600 RPM saves a lot of energy. The less the Pump reaches its maximum power, the less it uses energy.
Two-speed Pumps offer both high and low speeds. If it works mostly at low speed, the monthly costs can drop to 30 to 50 dollars, while it still filters the water right four the most home Pool setups. A variable-speed Pump, that runs 24 hours a day at low speed, uses only around 75 watts, what results in almost 6 dollars per month.
That costs less than 75 dollars per year.
Big pools need more powerful Pumps, that use more energy. The location of the Pool also affects the monthly power costs. Running the Pump overnight, during off-peak hours, when the prices are lower, is another way to save.
One owner of a Pool switched from a single-speed to a variable-speed Pump and saved around 50 dollars monthly. In some cases, a Pool Pump accounts for half of the whole home power use in a month. That is quite a bigpattern, if one thinks about it.
Check your price per kilowatt hour to help guess the real cost for any specific case.
