how much does it cost to heat a pool for a day


Author: Poolking - Swimming Pool Equipment Manufacturer

The costs of heating your swimming pool can vary depending on a number of factors. Naturally, the bigger your pool is, the more it will cost to heat for a day. There are a few different heating options available to you, such as electric, gas, or solar heating, and each carries its own cost considerations. In this article, we’ll explore just how much it might cost to heat your swimming pool for a day.

Defining the Costs of Heating a Pool

Before we can dive into the costs, it’s important to understand just how pool heating works. Generally, pools are heated using a heating source (such as a heater or solar panels) that heats water that is then circulated through the pool. The warmer the water, the more energy it takes to maintain it. So, the size of your pool and the desired temperature will be the largest factors in determining how much energy it will take to heat your pool.

Factors that Impact Pool Heating Costs

Along with the size of your pool, here are a few other factors to consider when calculating the cost of heating your pool for a day:

1. Temperature Desired: If you want to heat your pool to a hotter temperature, you’ll also need to spend more energy, and therefore money, to get it there. Generally, swimming pools are kept around 78-82 degrees Fahrenheit.

2. Type of Heating: There are several different types of pool heating systems, and the costs will vary based on which one you choose. Some heating options are more energy efficient than others, such as solar heating, so you’ll need to determine what works best for your budget and pool size.

3. Outdoor Temperature: If you’re in a cooler climate, the air temperature will naturally cool your pool down faster. It will take more energy to keep your pool at the desired temperature in cooler weather.

4. Location: Your location can also impact the cost of heating a pool. Electricity and gas rates vary by region, and some areas are more prone to cooler temperatures or colder seasons.

5. Efficiency of Pool Cover: One simple way to keep costs down is by using a pool cover to trap heat in your pool. Without a cover, more heat is lost to the air, which will raise your costs over time.

Calculating the Cost of Heating a Pool

Now that we’ve covered the key factors impacting the cost of heating your pool, let’s take a closer look at how much it might cost. The average pool owner in the United States can expect to spend about $50 to $150 per month on heating during the swimming season. However, this will depend on the size of the pool, temperature preferred, and the type of heating installed.

On average, electrical heating will run you between $300 to $1,500 per year. For gas heating, you’ll typically spend about $200 to $1,000 each year. A solar pool heater can vary depending on a number of circumstances, such as the size of your pool, location, and the cost of installation. For the solar option, initial install can cost anywhere between $3,500 to $8,000, with an annual operation cost between $0 and $100.

One efficient way to keep costs low while still allowing for a heated pool with a longer swimming season is with a heat pump. Heat pumps require 70-80% less electricity compared to typical electric heating while also being more cost efficient. These systems are ideal in warmer climates where temperatures are not prone to reach below 40 degrees Fahrenheit. On average, you should expect to spend $125 to $400 per month on operating a heat pump.

Cutting Costs with Solar Heating

Solar heating is becoming more popular among pool owners since it is environmentally friendly and cost efficient. The sun’s energy is free after all! With solar pool heating, a network of small pipes and solar panels are installed on your roof. The solar panel then heats up the water and sends it back into your pool. The initial setup cost can be pricey, but you’ll see cost savings through reduced electric bills since it’s powered by sun rays.

On average, a solar heater that can handle a 20,000-gallon pool cost about $3,500 – $8,000. While it is the most expensive option for installation, solar panels for heating a pool can last nearly 15-20 years with regular maintenance.


Heating your pool requires energy, sometimes a lot of energy, depending on various factors like pool size, heating system, and more. Ultimately, the cost of heating your swimming pool will depend on your specific preferences and circumstances. However, by factoring in the size of your pool, type of heating, efficiency of pool cover, and annual average outdoor temperature, you can determine the best heating option for you with the lowest running cost while still having an optimal swimming season. With a little bit of savvy and calculation, you can ensure the perfect swimming temperature for your family year after year.
