This inverter heat pump is designed to provide 21,000 BTU for pools up to 7000 gallons. Its inverter technology helps manage energy usage while maintaining your desired water temperature.
This pump is a good fit for those who want more control over their pool’s climate. It isn’t suitable for pools larger than 7000 gallons.
Pros
- Efficient inverter heating technology.
- Handles up to 7000 gallons.
Cons
- Limited to smaller pool sizes.
5. Swimming Pool Heater for Above Ground Pool 18450BTU

6. INTEX Solar Pool Cover for 15ft Round Above Ground Swimming
Best for: Reducing heat loss through evaporation.
This cover sits on the surface of your pool to trap solar energy during the day. It also acts as a barrier to prevent heat from escaping into the air at night.
It’s a great passive tool for 15ft round pools. If you want a significant temperature boost in a very short time, this cover won’t provide the same results as a pump.
Pros
- Retains existing water heat.
- Reduces water evaporation.
Cons
- Requires manual placement daily.

How to Choose in Sixty Seconds
Which type of heater is best for my pool?
Choose based on your power access and pool size. Electric heat pumps provide steady, reliable warmth regardless of the weather, while solar mats and covers rely on sunlight.
Do I need a professional to install these?
Most smaller pumps and solar mats are designed for user-friendly installation. However, always confirm your electrical setup can handle the load of a heat pump before ordering. If you’re unsure about wiring a 110v or 220v unit, consulting a professional is the safest path to ensure your setup meets local safety codes.
What should I check before buying?
Always check your pool’s total gallon capacity against the heater’s rating. A heater that’s too small for your pool will struggle to reach your target temperature. Also, consider the local climate; if you have many cloudy days, an electric heat pump will perform much better than a passive solar mat.
Closing
The 16000BTU Pool Heat Pump stands out for its consistent, reliable performance in smaller pools, while the Intex Solar Pool Cover remains the best choice for passive heat retention. Evaluate your pool’s volume and your local climate before making your final selection to ensure the best results.

Frequently Asked Questions
Is the simplest option enough to heat my pool?
A solar cover or mat is often enough for a small pool in a very sunny climate. These simple tools work by retaining the heat the sun provides, which can be sufficient for casual use. If you need steady warmth in cooler weather, you’ll likely need an electric heat pump.
Can I use these heaters for both above ground and inground pools?
Some models, like the 18450BTU Pool Heater, are designed for specific pool types, while others are more flexible. Always check the manufacturer’s listing to see if the unit is rated for your pool construction. The listing doesn’t mention warranty terms.
Final Thoughts
Choosing the right method depends on your local weather and how often you plan to swim. Before you make a final decision, check your pool’s current cover situation, as it’ll keep that hard-earned heat from escaping overnight. You’ll be enjoying comfortable, warm water in your own backyard before you know it.
