Top-Rated Gas & Electric Pool Heaters and Energy-Efficient Heat Pumps

The perfect pool is neither too hot nor too cold. A comfortable and enjoyable 77-85 degrees provides the optimal experience. However, depending on where you live and your climate, keeping a continuous temperature throughout the summer or even all year requires heating your pool.

A pool heater or a pool heat pump are the most common heating solutions that allow you to extend your swimming season. Both enable energy-efficient heating for every budget, and there are various factors to consider when determining the best heating solution for your pool.

Are pool heaters gas or electric?

Pool heaters can be either gas or electric, depending on the model and type of swimming pool.

Gas heaters use natural gas or propane, while electric heaters use standard electricity. Gas heaters are typically more expensive to install but may provide cost savings in the long run as they are generally more efficient than electric models. Additionally, gas heaters have the advantage of being able to provide a faster heating time and higher temperatures than an electric heater can manage. 

Electric pool heaters, however, tend to be less expensive upfront and require less maintenance over time. They also offer more precise temperature control and are quieter than their gas counterparts. They could be more costly to run long term depending on your local cost of electricity.

FAQs 

Is it cheaper to run a pool heater continuously?

No, it is not cheaper to run a pool heater continuously. It is a myth that it takes more energy to reheat a pool than to maintain a constant temperature. To save energy and money, you should turn down the temperature or turn off your pool heater whenever the pool will not be used for several days.

How to pick the right pool heater?

Choosing the right pool heater involves finding the best size, considering your climate, and selecting the most suitable heater type for your needs.

1. Determine Pool Heater Size (BTU Output)
2. Factor in External Conditions and Usage
3. Choose a Heater Type

Are gas or electric pool heaters better?

Neither gas nor electric pool heaters are universally "better"; the optimal choice depends on your specific climate, budget, pool usage frequency, and environmental priorities.

Choose a gas heater if:    

• You need to heat your pool quickly for occasional or spontaneous use.
• You live in a colder climate where ambient air temperature frequently drops below 55°F (13°C).
• You prefer a lower upfront investment.

Choose an electric heat pump if:

• You live in a warmer or mild climate.
• You plan to heat your pool consistently for extended periods or all season.
• You prioritize long-term savings on energy bills.
• You value a longer heater lifespan and lower environmental impact.

Is it cheaper to heat a pool with natural gas or propane?

Generally, natural gas is cheaper than propane for heating a pool. Both natural gas and propane heaters are efficient at heating pools quickly but are known for higher energy consumption compared to some other heating methods.

Do pool heaters use a lot of electricity?

Yes, pool heaters can consume a lot of energy, but the amount of electricity used and the overall operating cost vary dramatically based on the type of heater, your climate, pool size, and usage habits. While some heaters directly use a lot of electricity, others rely on gas or solar power, influencing their running costs.
