In this guide, we’ll break down all the key factors that influence pool-related electricity costs, how different types of pools compare, and what you can do to keep your energy use—and bills—under control.
The Short Answer: It Varies Based on System Type and Usage
In a general sense, having a swimming pool can increase your monthly electric bill by $30 to $100, depending on the pool’s size, how much you use it, and the equipment involved. However, with features like heaters, saltwater chlorinators, and lighting, the cost can go higher—especially during the warmer months.
Let’s dive deeper into the details.
1. The Main Electric Components of a Swimming Pool
Before we can calculate how much your pool is costing you in electricity, it helps to understand the different components that contribute to energy use.
1.1 Pool Pump: The Biggest Energy User
The pool pump is typically the main contributor to increased electricity usage. Here’s a breakdown:
- Runs daily to circulate and filter the water
- Uses about 1–2 kWh (kilowatt-hours) per day for a standard single-speed pump
- Can consume up to $100 per month if run continuously
For example, if you use a 1.5 horsepower standard electric pool pump for 8 hours a day and your electricity rate is $0.16 per kWh, your monthly running cost could be around $58.
Tip: Switching to a variable-speed pool pump can cut energy usage by up to 90%, significantly lowering your electric bill.
1.2 Pool Heater: Seasonal Energy Spike

How does owning a pool affect my electric bill?
Owning a pool can have a significant impact on your monthly electric bill, primarily due to the energy required to operate the pool pump, heater, and sometimes lighting and automatic cleaners. The most energy-intensive component is typically the pool pump, which circulates water through the filtration system. Depending on the size of the pool and how often the pump is run, this can add anywhere from $30 to $150 per month to your electricity bill.
Additional factors like the use of a pool heater, especially in cooler climates, can further increase energy consumption. Heating a pool can double or even triple the added electric costs, depending on the heating method and usage patterns. While other features like pool lighting or saltwater chlorinators also consume electricity, their impact is relatively minor compared to the pump and heater. Understanding your equipment’s energy use is the first step in managing the cost of your pool.
What is the average cost of running a pool pump?
The cost of operating a pool pump varies depending on the pump’s horsepower, how long it runs daily, and local electricity rates. On average, a standard single-speed pump can cost between $10 and $50 per month to run, though this can be higher in larger pools or in areas where filtration needs to run longer due to environmental factors. The pump must circulate the entire volume of the pool several times per week to maintain water clarity and sanitation.
Choosing a variable-speed pump can significantly reduce operating costs, sometimes by as much as 75%, since it allows you to adjust the pump speed based on demand. These pumps are more energy-efficient and are worth the higher upfront cost over time due to electricity savings. Additionally, using a timer to run the pump during off-peak hours—when electricity rates are lower—can also help cut costs. It’s important to consult with a pool professional to find the best setup for your situation.
How much does it cost to heat a swimming pool?
Heating a swimming pool can vary in cost depending on the type of heater, the size of the pool, and the local climate. Gas heaters are generally more expensive to operate than heat pumps, using propane or natural gas for heating. For example, a gas heater might cost as much as $300 to $600 per month in colder areas where heating is needed year-round. In contrast, a heat pump uses electricity more efficiently and can cost about $100 to $300 per month during peak usage.
Solar pool heaters are the most cost-effective long-term solution, with little to no operating costs after the initial installation. These systems can be highly efficient in sunny climates and significantly extend the swimming season. Pool covers also complement heating systems by reducing evaporation and heat loss, thus cutting heating expenses by up to 50%. It’s important to compare all available heating options and evaluate their long-term costs and efficiency based on your location and usage patterns.
Do saltwater pools use less electricity than traditional chlorine pools?
Saltwater pools generate chlorine through a process called electrolysis, which involves a salt chlorine generator. While this system does use electricity, it generally does not consume significantly more power than a traditional chlorine pool. The main energy draw for both types of pools remains the pump and heater. In fact, because saltwater pools can maintain more stable chlorine levels, pool owners may benefit from reduced use of chemicals and less time spent managing the system.
However, the salt chlorine generator does add to electrical consumption, typically costing around $5 to $15 extra per month depending on usage and electricity rates. It’s essential to note that a saltwater pool requires regular maintenance, such as cleaning the generator cell, and its longevity may be affected by continuous usage. The energy cost difference between saltwater and chlorinated pools is relatively small, so the decision should be based more on maintenance preferences and water feel than on electricity savings alone.
Can I reduce the electricity usage of my pool without compromising cleanliness?
Yes, there are several ways to reduce your pool’s electricity usage without sacrificing cleanliness. The first and most impactful step is upgrading to a variable-speed pump, which can operate at lower speeds when full filtration is not needed. This results in significant energy savings over time. Additionally, routine maintenance such as cleaning the filter and checking for leaks ensures the system runs efficiently, reducing unnecessary energy waste.
Using a pool cover when the pool is not in use can also reduce heat loss and evaporation, cutting the demand on heaters and chemical treatments. Running the pump during off-peak hours, as determined by your electricity provider, can also help. Shortening the daily runtime of the pump by even an hour or two—without neglecting filtration needs—can add up to noticeable savings. With a few smart adjustments and equipment investments, you can maintain a clean, enjoyable pool while keeping energy use and costs under control.
How much can I save with solar-powered pool equipment?
Solar-powered pool equipment, especially solar pool heaters and solar-powered pumps, can offer significant savings on your electric bill. Solar pool heating systems, which use panels mounted on rooftops or nearby ground space, absorb the sun’s energy and transfer it to the pool water. These systems have high initial installation costs but little to no ongoing operating costs, and they can extend your swimming season in many climates.
A solar-powered pool pump, while less common, can further reduce reliance on the electric grid by operating directly on solar energy. These pumps are ideal for smaller pool applications or in areas that receive consistent sunlight. Overall, adopting solar technology can reduce a pool’s electricity impact by 50% or more, depending on the system size and usage. With available tax credits and rebates in some regions, solar pool equipment can be a cost-effective investment over time.
What are the best practices for managing pool electricity costs?
To effectively manage pool-related electricity costs, start by performing an energy audit of your current equipment. Understanding how much each device—pump, heater, lights, chlorinator—uses daily is crucial. Once you know where your biggest energy draws are, you can prioritize energy-saving measures such as upgrading to energy-efficient pumps, installing a solar heating system, or using smart controllers that optimize system operation.
Proper maintenance is also a key cost-saving factor. A clean, well-balanced pool requires less filtering and chemical treatment, allowing you to run the pump less without compromising cleanliness. Adding a solar cover can reduce heat loss and evaporation, making the heater more efficient. Additionally, programming pool equipment to run during off-peak hours can also cut down on energy expenses. Applying these best practices consistently can help you enjoy your pool more affordably over time.
