How I picked
When I set out to find the best above ground pool heaters, I knew there wasn't a single "perfect" heater for everyone. It really depends on your pool size, how quickly you want to heat it, your budget, and even your local climate. I evaluated each model based on several key factors:
- Heating Power (BTU/Wattage): This was the absolute first thing I looked at. Is the heater powerful enough for the pool size it claims to serve? A heater that's too small will run constantly and still not get the water warm enough, which is frustrating and wasteful. I focused on units that had clear BTU or wattage ratings and matched them against recommended pool volumes.
- Type of Heater: I looked at both heat pumps and electric resistance heaters. Heat pumps are generally more energy-efficient in the long run, especially in warmer climates, but have a higher upfront cost. Electric resistance heaters are typically cheaper to buy and heat water faster but use more electricity.
- Ease of Installation and Use: For above ground pools, simplicity is key. I considered how easy it would be for someone to install and operate the heater, whether it required specialized plumbing or electrical work, and how intuitive the controls were.
- Durability and Materials: Pool equipment lives outdoors and deals with water, so material quality is crucial. Titanium heat exchangers, stainless steel components, and robust casings were points I noted for longevity.
- Safety Features: As with anything involving electricity and water, safety is paramount. I prioritized heaters with built-in GFCI protection and reliable thermostats.
- User Feedback: I scoured customer reviews to see what real users were saying about performance, reliability, and any quirks they encountered. Looking at aggregate ratings and common themes in feedback helped paint a clearer picture beyond just the spec sheet.
I didn't focus on gas heaters as they often require more complex installation and venting, which is less common for typical above ground pool setups. My goal was to find options that were accessible, effective, and offered good value for the average above ground pool owner.
Buying guide — what actually matters for best above ground pool heater
Thinking about getting a heater for your above ground pool? That's a smart move to extend your swimming season! But with so many options out there, it can feel a bit overwhelming. Let's break down what really counts when you're choosing the right one.
What size pool do you have?
This is your starting point. Heaters are rated for specific pool sizes, usually in gallons. Using a heater that’s too small for your pool will mean it runs constantly and might never get your water to a comfortable temperature. Conversely, an overpowered heater for a tiny pool might be overkill and waste energy.
Always check the manufacturer's recommended pool volume against your pool's approximate gallon capacity.
How fast do you need it to heat?
This is where the type of heater comes into play.
- Electric Resistance Heaters: These are like giant toasters for your pool. They heat water very quickly, which is great if you want to go from chilly to cozy in a few hours. However, they use a lot of electricity.
- Heat Pumps: These are more energy-efficient because they use electricity to move heat from the air into your pool water, rather than directly generating heat. This means they use less electricity overall, saving you money on your energy bill, but they take longer to heat the water, especially when the air is cool.
What's your budget?
Heaters span a wide price range. Electric resistance heaters are typically the most affordable to purchase upfront. Heat pumps have a higher initial cost but can save you money over time through lower energy consumption. Consider not just the purchase price but also the estimated operating cost based on your local electricity rates and how often you plan to use the heater.
Installation and electrical needs
Most above ground pool heaters will require a dedicated electrical circuit. For electric resistance heaters, this might be a standard 120V outlet if the wattage is low enough (like 1500-2000W immersion heaters). However, higher-wattage electric heaters (like 11KW, 15KW) and most heat pumps will need a 220V/240V dedicated circuit. If you don't have this readily available, you'll need to factor in the cost of hiring an electrician.
Heat pumps also require proper ventilation and a level pad for installation.
Safety features are non-negotiable
When dealing with electricity and water, safety should always come first. Look for heaters with built-in Ground Fault Circuit Interrupter (GFCI) protection. This is a crucial safety device that can quickly shut off power if it detects an electrical imbalance, preventing shock hazards. A reliable thermostat is also key for maintaining a safe and comfortable temperature and preventing overheating.
Durability and materials
Since your heater will be exposed to the elements, its construction quality matters. Look for durable materials, especially for components that come into contact with pool water. Titanium is a prized material for heat exchangers because it’s highly resistant to corrosion from pool chemicals. Stainless steel is also common for many components and guards.
Checking reviews for mentions of rust or premature wear can give you clues about long-term durability.
Frequently Asked Questions (FAQ)
Is an above ground pool heater worth the cost?
For many, the answer is a resounding yes. A heater can extend your swimming season by several weeks, making your pool enjoyable on cooler spring and fall days. It also ensures a consistently comfortable water temperature, which significantly enhances the swimming experience. While there's an upfront cost and ongoing energy expenses, the increased usability and enjoyment of your pool often make it a worthwhile investment.
How long does it take for a pool heater to warm up the water?
The time varies greatly depending on the heater's power, the pool's size, and the ambient air temperature. A small 2000W immersion heater might warm a small inflatable hot tub in an hour or two. A powerful 15KW electric heater could warm a medium-sized above ground pool by a few degrees over several hours. Heat pumps are generally slower to bring water up to temperature initially but maintain it efficiently.
Expect anywhere from a few hours to a full day or more for significant temperature increases in larger pools.
Can I use an electric pool heater indoors?
Generally, no. Most above ground pool heaters are designed for outdoor use and require proper ventilation to operate safely and efficiently. Some electric resistance heaters meant for smaller volumes like tubs might be used near indoor spaces or covered patios, but they still often require ventilation to prevent excessive humidity. It's always best to check the manufacturer's specifications and intended use for any heater model.
What maintenance do above ground pool heaters typically require?
Regular maintenance is key to keeping your heater running efficiently and safely. This usually includes keeping the filter for your pool pump clean, as debris can impact water flow to the heater. For heat pumps, you'll want to periodically clean the exterior coils to ensure good airflow. For electric resistance heaters, check for any mineral buildup or corrosion, especially on heating elements if they are accessible.
Always follow the manufacturer's specific maintenance schedule.
Do pool heaters use a lot of electricity?
This depends heavily on the type and power of the heater, as well as how often and how intensely you use it. Electric resistance heaters, which directly convert electricity to heat, are the most power-hungry. Heat pumps are significantly more energy-efficient because they leverage heat from the air and can use up to 50-70% less energy than electric resistance for the same heating effect. Running a heater constantly to maintain a high temperature will naturally result in higher electricity bills.
Final verdict
To sum it all up, finding the right heater can transform your above ground pool experience. For overall performance and convenience, the AQUASTRONG Swimming Pool Heat Pump stands out as an Editor's Choice for its dual heating and cooling capabilities and energy efficiency. If you're looking for a robust unit with smart features, the Electric Pool Heater 30 000 BTU is a top contender, especially with its user-friendly WiFi control. And for those on a tighter budget who still want effective heating, the Electric Pool Heater Inground & Above offers a great value proposition.
Consider your pool size, how quickly you need it heated, and your budget to pick the best fit for your backyard oasis.
