Natural Gas or Propane: Which is Right for You?
One of the key decisions pool owners face when purchasing a gas heater is choosing between natural gas and propane. Both fuels have distinct advantages:
Natural Gas: If your property already has a natural gas line, this is often the most convenient and cost-effective option. Natural gas heaters typically have lower operating costs in regions where utility gas prices are stable.
Propane: For rural or off-grid homeowners without access to natural gas, propane provides flexibility. While propane can be more expensive per BTU, propane heaters deliver the same heating speed and performance as their natural gas counterparts.
Both fuel types are capable of heating water quickly, often raising pool temperatures by several degrees in just hours. For those who want on-demand heating — say, warming the spa before an evening soak — gas heaters remain the fastest solution available.
Top Pool Heat Pumps of 2025
While gas heaters excel in speed, heat pumps shine in efficiency, especially in warm and mild climates where they can harness ambient air to heat the pool. According to the DOE’s pool heating guidance, heat pumps often cost more upfront but save significantly on long-term energy expenses.

Pool Heaters vs. Heat Pumps
So, which heating technology is better — gas heaters or heat pumps? The answer depends on your climate, usage habits, and budget.
Gas Heaters (Natural Gas or Propane)
🥇 Best for: Cold climates, large pools, and spa owners who want rapid on-demand heating.
✅ Pros: Heats water quickly, unaffected by outdoor temperature.
❌ Cons: Higher ongoing fuel costs, less energy efficient.
Heat Pumps
🥇 Best for: Warm and mild climates where efficiency matters more than speed.
✅ Pros: Extremely energy efficient, lower operating costs, eco-friendly.
❌ Cons: Slower heat-up times; performance drops in colder air temperatures.
Many homeowners choose gas heaters for spas and heat pumps for pools, or even install both for maximum flexibility.
Choosing the Best Product for Your Pool
When selecting the right pool heating solution, consider:
- Pool Size & Volume – Larger pools may require higher BTU gas heaters or large-capacity heat pumps.
- Climate & Location – Heat pumps thrive in warmer regions; gas heaters dominate in cooler climates.
- Usage Habits – If you want to swim year-round or heat a spa quickly, gas heaters may be worth the fuel cost. For those looking to maintain a comfortable temperature consistently, a heat pump is usually more cost-effective.
- Budget – Gas heaters typically cost less upfront but more to operate. Heat pumps cost more initially but offer significant long-term savings.
- Automation & Integration – Most leading models are automation-ready, making it easier than ever to manage heating from your smartphone or pool system controller.
Pricing a Pool Heater or Heat Pump
When it comes to cost, the conversation starts with equipment price. Gas heaters generally enter the market at a lower price point. A compact 175,000–200,000 BTU model often sells for around $1,800 to $2,500. Mid-range heaters in the 250,000–300,000 BTU class usually run between $2,500 and $3,500, while the biggest 350,000–400,000 BTU units for large pools can exceed $5,000. Heat pumps begin higher. Most standard residential models range from $2,800 to $4,000, and larger 120,000–140,000 BTU or inverter-driven units with heat-and-chill features can climb to $6,000 or even $7,500.
The real difference shows up in monthly energy bills. A gas heater running on natural gas typically costs $200 to $400 a month to operate, depending on pool size and how frequently it’s used. Propane can push those costs even higher. Electricity costs for a heat pump are much lower, usually falling between $50 and $150 per month in most regions. That efficiency makes heat pumps especially attractive for homeowners in warmer climates where the units can draw plenty of heat from the surrounding air.
Over the lifetime of the equipment, gas heaters tend to last five to ten years, which means most owners will spend between $12,000 and $18,000 over a decade when fuel and equipment are combined. Heat pumps last longer—typically ten to fifteen years—and although they cost more to install, the lower operating expense brings total ten-year ownership costs closer to $7,000 to $10,000.
