Whether you’re upgrading your current pool heating system or installing one for the first time, choosing the right pool heat pump is essential for energy efficiency, performance, and comfort. Not all heat pumps are created equal—and the size of your pool plays a big role in determining the best option. In this blog, we’ll explore what makes a great heat pump for small and large pools, and how to choose one that fits your needs perfectly.
Why Pool Size Matters When Choosing a Heat Pump
The size of your pool directly affects how much heating power (measured in BTUs) your heat pump needs to maintain the desired temperature. A heat pump that’s too small will struggle to heat the water efficiently, while one that’s too large may cycle on and off too frequently, reducing lifespan and wasting energy.
- Small Pools (up to 15,000 gallons) typically require a heat pump with 50,000 to 75,000 BTUs.
- Medium to Large Pools (15,000 to 30,000+ gallons) benefit from models with 100,000 BTUs or more.
Best Pool Heat Pumps for Small Pools
If you have a small or plunge pool, look for compact, energy-efficient models that still offer reliable performance. A few popular models include:
- Hayward HP50HA HeatPro: Great for pools up to 13,000 gallons. It’s compact, quiet, and energy-efficient with a titanium heat exchanger.
- AquaCal TropiCal T55: Known for its durability and easy installation, ideal for small residential pools.
Key features to look for:
- Energy efficiency rating (COP)
- Quiet operation
- Corrosion-resistant materials
- Easy-to-use digital display
Best Pool Heat Pumps for Large Pools
For large pools, power and durability are top priorities. Larger heat pumps can handle higher water volumes and keep your pool warm, even in cooler weather.
Top models for larger pools include:
- Pentair Ultra Temp 120: Delivers 120,000 BTUs with advanced automation compatibility and energy-saving features.
- AquaCal Super Quiet SQ120: Offers powerful heating with one of the quietest operations in the industry, ideal for residential and commercial use.
Essential features:
- High BTU output (100,000+)
- Advanced control systems
- Compatibility with pool automation systems
- Weather-resistant housing
Installation and Maintenance Tips
- Location Matters: Install your heat pump in a well-ventilated outdoor area for optimal efficiency.
- Routine Maintenance: Clean the air filters and check for debris to ensure the heat pump runs efficiently.
- Professional Sizing: Always consult with a professional to ensure the heat pump matches your pool’s size, usage, and climate.
