Electric vs. Gas Pool Heaters: What’s the True Cost to Run One in Las Vegas?
Why are so many Las Vegas pool owners comparing electric and gas heaters?
In Las Vegas, your pool is usable almost year-round — but when the nights get cool or the winter chill sets in, heating becomes essential. The real question is: what’s the smarter choice — electric or gas?
Many homeowners assume electric is cheaper because it’s “energy efficient,” while others stick with gas for faster heating. The truth? Both systems work well in the desert, but the real cost to run them depends on how and when you swim.
At Pool Supply Depot, we help Las Vegas pool owners run these numbers every day. Here’s what you need to know before choosing between electric and gas pool heating — and what it actually costs to keep your pool warm in Nevada’s desert climate.
How does an electric pool heater work — and when does it make sense?
An electric pool heater (often called a heat pump) doesn’t create heat — it transfers it. It pulls warmth from the surrounding air and moves it into your pool water. That means it’s most efficient when the air temperature stays above 50°F — which covers most of Las Vegas’s swimming season.
Why homeowners love it:
-
It’s energy efficient, especially for daily or long-term heating.
-
It works quietly and steadily, maintaining temperature over time.
-
It has lower operating costs once installed.
When it’s not ideal:
During cold nights or sudden temperature drops, heat pumps lose efficiency because there’s less warm air to pull from. They can take longer to heat your pool compared to gas models.
If you swim regularly from spring through fall, an electric heat pump can save you hundreds annually compared to gas.
How does a gas pool heater work — and who benefits most?
A gas pool heater (natural gas or propane) burns fuel to create instant heat. It can raise water temperature by several degrees in just a few hours — regardless of outdoor conditions.
Why homeowners love it:
-
Fast heating — perfect for spas or quick weekend swims.
-
Reliable performance in any weather.
-
Great for families who use the pool occasionally.
When it’s not ideal:
Gas heaters are less energy-efficient and can be expensive to run if used frequently. For everyday heating, those costs add up quickly — especially with fluctuating natural gas prices in Nevada.
If you use your pool only occasionally or want on-demand spa heating, gas is the clear winner in convenience.
What’s the true cost to run each in Las Vegas?
Let’s break down the numbers based on average Las Vegas utility rates and typical residential pool sizes (15,000–20,000 gallons).
| Type | Average Cost to Run per Hour | Estimated Monthly Cost (Moderate Use) | Ideal Use Case |
|---|---|---|---|
| Electric Heat Pump | $1.00 – $1.50/hour | $100 – $200 | Daily or extended heating |
| Gas Heater (Natural Gas) | $3.00 – $7.00/hour | $300 – $600 | Quick or occasional heating |
| Gas Heater (Propane) | $5.00 – $9.00/hour | $400 – $700 | Areas without natural gas lines |
Key takeaway:
While gas heaters cost less upfront ($1,800–$3,000), their long-term operating costs can double or triple those of heat pumps. Heat pumps cost more to install ($3,000–$5,000) but typically pay for themselves within 2–3 years of regular use.
At Pool Supply Depot, we help homeowners run custom energy comparisons based on their usage, pool size, and local utility rates — because even small variations in your swim habits can change the math.
How does Las Vegas’s desert climate affect your heating choice?
Las Vegas’s dry desert air creates huge temperature swings — warm days and chilly nights. This makes heat pumps highly efficient from March through October, when daytime highs stay above 70°F.
But in winter, especially during cold nights, gas heaters outperform. They heat quickly regardless of air temperature.
Smart homeowners often use both: a heat pump for everyday heating and a gas heater as a backup for the coldest months or spa use.
This hybrid approach provides year-round comfort while keeping energy bills low.
Which one lasts longer — electric or gas heaters?
-
Heat Pumps: 10–15 years lifespan with minimal maintenance.
-
Gas Heaters: 5–10 years lifespan, depending on usage and water chemistry.
Heat pumps have fewer moving parts, so they typically last longer and require less servicing. Gas heaters, while powerful, need more frequent maintenance — especially in areas with hard water like Las Vegas.
So… which is truly the best option for Las Vegas pools?
Here’s the simple answer: it depends on how you use your pool.
-
If you swim several times a week and want consistent warmth → Electric Heat Pump.
-
If you swim occasionally or heat a spa on-demand → Gas Heater.
-
If you want year-round flexibility → Hybrid system (heat pump + gas).
