10 Best Above Ground Pool Heaters Electric - Best Deals in 2024

What is the best option for heating above ground pools?

When it comes to heating above-ground pools, the best option depends on various factors such as budget, desired heating speed, energy efficiency, and availability of resources. Here are a few commonly used heating options for above-ground pools:

1. Heat Pumps: Heat pumps are considered one of the most efficient and cost-effective options for heating above-ground pools. They extract heat from the surrounding air and transfer it to the pool water. Heat pumps are energy-efficient, provide consistent heating, and are suitable for moderate climates. They work best when the ambient air temperature is above 50°F (10°C).

2. Solar Heating: Solar heating is an environmentally friendly option that utilizes the energy from the sun to heat the pool water. Solar panels or collectors capture the sun's heat and transfer it to the pool through circulation. While solar heating may have higher upfront costs, it can be cost-effective in the long run due to minimal operating costs.

3. Electric Resistance Heaters: Electric resistance heaters use electricity to generate heat and warm the pool water. They are quick to heat the pool and can work in any climate. However, they tend to be less energy-efficient and may have higher operating costs compared to other options, especially for larger pools or prolonged heating periods.

4. Gas Heaters: Gas heaters, powered by natural gas or propane, provide fast and powerful heating for above-ground pools. They can quickly raise the water temperature, making them suitable for all climates. Gas heaters are effective regardless of air temperature but can have higher operating costs compared to other options.

Consider your budget, energy efficiency, installation requirements, and local climate when selecting the best option for heating your above-ground pool. It's recommended to consult with a pool professional or heating specialist who can assess your specific needs and provide recommendations based on your circumstances.

How big of an electric heater do I need for my pool?

To determine the size of an electric heater needed for your pool, you'll need to consider several factors, including the pool size, desired heating speed, average ambient temperature, and insulation. Here's a general guideline to estimate the heater size for electric pool heaters:

1. Calculate the Heat Loss: Determine the heat loss of your pool by subtracting the desired pool temperature from the average ambient temperature. For example, if you want to heat the pool from 70°F to 80°F and the average ambient temperature is 50°F, the heat loss is 30°F.

2. Calculate the Pool Surface Area: Measure the surface area of your pool. If it's rectangular or square, multiply the length by the width. For irregular shapes, you may need to break it down into smaller sections and calculate the area for each section separately.

3. Calculate the BTU Requirement: To estimate the BTU (British Thermal Unit) requirement, multiply the pool surface area by the heat loss and then multiply the result by a heat transfer factor. A common heat transfer factor for electric pool heaters is 12-15 BTUs per square foot per hour.

4. Choose the Heater Size: Once you have the estimated BTU requirement, you can choose an electric pool heater that matches or exceeds that value. Electric heaters are typically available in various sizes, ranging from around 5,000 BTUs to 60,000 BTUs or more.

It's important to note that this is a general guideline, and it's recommended to consult with a pool professional or heating specialist who can assess your specific pool's characteristics, insulation, and local climate conditions to provide a more accurate recommendation for the electric heater size needed for your pool.

How long does it take an electric pool heater to heat a pool?

The time it takes for an electric pool heater to heat a pool can vary based on several factors, including the size of the pool, the desired temperature increase, the BTU output of the heater, and the ambient conditions. Electric pool heaters typically heat the water at a rate of around 1-2 degrees Fahrenheit per hour.

To estimate the time it will take to heat your pool, you can use the following formula:

Time (in hours) = Temperature Rise (in degrees Fahrenheit) / Heating Rate (degrees Fahrenheit per hour)

For example, if you want to raise the pool temperature by 10 degrees Fahrenheit and the heater has a heating rate of 2 degrees Fahrenheit per hour, it would take approximately 5 hours to achieve the desired temperature increase (10 degrees Fahrenheit / 2 degrees Fahrenheit per hour = 5 hours).

It's important to note that this is a general estimation, and the actual heating time can be influenced by factors such as the size and insulation of the pool, outdoor temperature, and initial water temperature. Additionally, starting with colder water or colder ambient conditions may require more time for the heater to reach the desired temperature.

It's recommended to consider the specific characteristics of your pool, consult the manufacturer's guidelines for your electric pool heater, and monitor the heating progress to ensure safe and efficient heating.

How long do electric pool heaters last?

The lifespan of an electric pool heater can vary depending on several factors, including the quality of the heater, usage patterns, maintenance, and environmental conditions. On average, electric pool heaters can last between 5 to 10 years. However, with proper care and maintenance, some electric pool heaters have been known to last even longer.

To maximize the lifespan of an electric pool heater, consider the following:

1. Regular Maintenance: Follow the manufacturer's instructions for regular maintenance, including cleaning or replacing filters, inspecting and cleaning heating elements, and checking electrical connections. Regular maintenance can help prevent issues and prolong the lifespan of the heater.

2. Water Chemistry: Maintain proper water chemistry in your pool, including pH balance and appropriate sanitizer levels. Imbalanced water chemistry can lead to corrosion or scale buildup, which can affect the heater's performance and longevity.

3. Proper Sizing: Ensure that the electric pool heater is properly sized for your pool. Undersized heaters may need to work harder, leading to increased wear and potential premature failure. Consult with a pool professional or heating specialist to determine the appropriate size for your specific pool.

4. Professional Installation: Have the electric pool heater installed by a qualified professional to ensure proper installation, wiring, and adherence to safety guidelines. Improper installation can lead to performance issues and may impact the lifespan of the heater.

It's important to note that the lifespan of an electric pool heater can vary based on individual circumstances and usage patterns. Regular inspections, timely repairs, and monitoring can help identify any issues early and extend the life of the heater. If you experience any problems with your electric pool heater, it's recommended to consult a professional technician or contact the manufacturer for guidance and support.
