How Much Does It Cost to Heat a Pool? Gas vs Heat Pump
The cost to heat a pool depends on your setup, but it comes down to two things:
Efficiency vs speed
Quick Answer
- Heat pump: lowest cost to run
- Gas heater: highest cost to run, fastest heating
Important Note
Every pool is different.
Your actual cost depends on:
- Climate
- Pool size
- Energy prices in your area
- How often you heat your pool
This is a general guide to help you choose the right direction.
Heat Pump Cost (Most Efficient Option)
Heat pumps use electricity to pull heat from the air.
Typical operating cost: lowest
Best for:
- Daily use
- Maintaining temperature
- Warm or moderate climates
If you have solar power, a heat pump is often the best option.
Gas Heater Cost (Fastest Heating)
Gas heaters generate heat directly using natural gas or propane.
Typical operating cost: highest
Best for:
- Fast heating
- Occasional use
- Cold climates
If you have access to low-cost gas or propane, this can still be a good option.
Heating Speed vs Cost
This is the biggest trade-off:
- Heat pump → slower, but much cheaper to run
- Gas heater → very fast, but more expensive
If your priority is:
- Lower monthly cost → heat pump
- Fast heat-up time → gas heater
Climate Matters
- Warm climates → heat pumps perform very well
- Cold climates → gas heaters are more reliable
Heat pumps rely on air temperature, so colder weather reduces efficiency.
What Should You Choose?
Choose a heat pump if:
- You want to save money long-term
- You use your pool regularly
- You live in a warmer climate
Choose a gas heater if:
- You want fast heating
- You use your pool occasionally
- You live in a colder climate
