Key Highlights

  • Gas heaters burn natural gas or propane; air-source heat pumps transfer heat from outdoor air.
  • Gas heating is often selected for faster heat-up, while heat pumps are often used to maintain temperature.
  • Compare the exact equipment, weather, energy rates, and intended pool use before choosing.
  • Fresh & Clear repairs natural gas and propane pool heaters.

Cooler weather changes the amount of heat a pool needs. NWS Las Vegas 1991–2020 normals put the average December high and low at 56.9°F and 39.6°F, and January at 58.5°F and 40.5°F. Those climate averages help describe the season, but they do not predict a heater’s output. If you want heated swimming beyond summer, compare equipment with the temperature you want to maintain and when you plan to use the pool.

A gas pool heater and an air-source pool heat pump operate differently. This guide explains the planning questions; suitability depends on the equipment and your pool.

How Each One Works

A gas pool heater burns natural gas or propane and transfers heat to the water. Pool size, heater output, weather, and heat loss affect heating time.

An air-source pool heat pump uses electricity to move heat from outdoor air into pool water. Check the specific model’s operating-temperature limits, output, and installation requirements.

Las Vegas 1991–2020 normals from NWS/NOAA, rounded to whole degrees. Air temperature is one planning factor. Heat-pump operating limits and output vary by model; compare manufacturer data with your pool and intended use. Climate averages do not predict heating performance.

Cold-weather performance varies by heat-pump model and conditions. Compare manufacturer output data at the temperatures when you intend to swim, rather than relying on a fixed March-to-November season.

Gas heating is often considered when faster heat-up is important. A professional must still account for pool volume, desired temperature rise, wind, and other heat losses.

Which One Fits How You Use Your Pool?

Quick guide

Which Pool Heater Fits You?

Gas Pool Heater

Compare faster heat-up needs, fuel supply, pool size, and heat loss.

Pool Heat Pump

Compare temperature maintenance, model limits, electricity rates, and airflow.

Combined Heating

Have a qualified professional assess compatibility, controls, and site requirements.

  • Heat on short notice: ask how quickly each option can meet your target temperature.
  • Consistent temperature: compare output, run time, and energy use over your intended season.
  • Combined heating: some systems support multiple heat sources; a professional must assess compatibility and installation.
Pro tip

Ask how the operating schedule affects your chosen equipment under local conditions. Follow the manufacturer’s settings and operating limits rather than a universal time-of-day recommendation.

Pro tip

Ask about a compatible cover and safe use to help manage evaporation and heat loss.

Keeping Either One Running

Both options need installation and maintenance appropriate to the specific model. Useful questions to ask include:

  • Water flow. Does the circulation system meet the heater’s requirements? See our pool heater warning signs guide.
  • Water balance. Which requirements apply to the heater and pool finish?
  • Access and clearances. What space and airflow does the manufacturer require?
  • Maintenance. What model-specific inspections and care are recommended? Our fall pool care checklist covers seasonal planning.
Smell gas? Leave the area without operating switches or appliance controls. From a safe location, call 911; for a suspected natural gas leak, also call Southwest Gas at 877-860-6020. Do not return until emergency responders say it is safe.

Frequently Asked Questions

Can a pool heat pump heat my pool in a Las Vegas winter?

It depends on the model’s operating limits and output, the desired temperature, and the pool’s heat loss. Have a qualified professional compare performance at the conditions when you intend to swim.

Which is cheaper to run, a gas pool heater or a pool heat pump?

Compare local gas and electricity rates, model performance, desired temperature, and how often you heat the pool. The cheaper option for one use pattern may differ for another.

Can I have both a gas pool heater and a pool heat pump?

Some systems support combined heat sources. A qualified professional must assess plumbing, controls, electrical and fuel requirements, and manufacturer compatibility for the proposed system.

What size pool heater do I need?

Sizing depends on pool volume, desired temperature rise, heating time, weather, and heat loss. Ask for a calculation for your pool and the specific proposed equipment rather than selecting from a generic BTU range.
