When people think of Las Vegas, they often envision endless sunny days and sipping by the pool. But during wintertime, the temperatures can drop and make it hard to enjoy your pool. But who says you have to give up your backyard oasis in the cooler months? With a few simple tips, you can keep your pool warm and enjoy it year-round.

Different Types of Pool Heaters

If you want to enjoy your pool all year round, a pool heater is a worthwhile investment. Pool heaters come in different types, including electric, gas, and solar-powered. An electric pool heater is the most common and reliable option, but it can be costly to operate. On the other hand, a gas heater is more cost-effective, but you will need a propane or natural gas connection. Lastly, a solar-powered pool heater uses energy from the sun, making it an eco-friendly option. A pool heater will enable you to control the water temperature and swim comfortably during the winter months.

Gas And Propane Heaters

Gas Heaters:

Gas-powered heaters are one of the most popular options for pool owners due to their affordability and effectiveness in heating up the water quickly. They work by igniting a flame in a combustion chamber that heats up the water as it passes through the unit. One thing to keep in mind is that gas heaters tend to be less energy-efficient than other types of heaters, which means that over time they can end up costing you more in monthly utility bills. If you’re looking for a short-term solution to heat up your pool quickly and don’t mind spending a little more on your energy bills, gas heaters can be a good choice.

How Do Gas Swimming Pool Heaters Work?

The basic principle is simple: gas (either propane or natural gas) is burned in a combustion chamber to produce heat, which is transferred to the pool water through a heat exchanger. The heated water is then pumped back into the pool to raise its temperature. Gas pool heaters come in different sizes and models, but most operate similarly and can heat a pool quickly and efficiently.

Pros of using gas swimming pool heaters

  • They can heat a pool quickly and maintain a consistent temperature, no matter the weather or time of day.
  • They are relatively affordable to install and operate, especially if you already have a gas line installed.
  • They are durable and can last for many years if maintained properly.
  • They can be used with any size or type of pool, including above-ground and inground pools.

Cons of using gas swimming pool heaters

  • They are not very energy-efficient compared to other types of heaters, such as solar or heat pump heaters. This means that they can be expensive to run, especially if you use them frequently.
  • They produce emissions that can contribute to air pollution and climate change. To minimize their environmental impact, it’s important to choose a model that is certified for low NOx (nitrogen oxides) emissions.
  • They require regular maintenance and cleaning to ensure proper functioning and safety.

Safety tips when using a gas swimming pool heater

  • Install a fence or barrier around your pool to restrict access to young children and pets.
  • Never leave the pool heater unattended or adjust the controls while swimming.
  • Keep flammable materials (such as cleaning chemicals or gas tanks) away from the heater and the pool area.
  • Have your gas pool heater serviced annually by a licensed technician to check for leaks, corrosion, and other issues.

Propane Heaters

Propane heaters are similar to gas heaters, but they use propane instead of natural gas to heat up the water. While they’re not quite as common as other types of pool heaters, they can be a great option if you live in an area where propane is readily available. They’re quick to heat up the water and relatively energy-efficient, but they can be more expensive than gas heaters over time due to the cost of propane.

How do swimming pool propane heaters work?

Propane heaters work by burning propane gas in a combustion chamber. The heat from the combustion chamber is then transferred to heat exchanger coils, which heat up water as it passes through the coils. The heated water is then returned to the pool, keeping it at a consistent temperature.

Pros of using a propane heaters

One of the main advantages of using a propane heater is its ability to quickly heat up your pool. This is especially useful during colder weather or evenings when your pool water may have dropped in temperature. Propane heaters are also known for being efficient in their energy use, which means less propane is needed to heat up your pool compared to other types of pool heaters.

Cons of using a propane heater

Despite their benefits, there are some downsides to using a propane heater. For one, they can be costly to install and maintain. Additionally, propane heaters require a constant supply of propane gas, which means you’ll need to refill your tank regularly. Finally, propane heaters are not the most eco-friendly option on the market, as they emit greenhouse gases and contribute to environmental pollution.

Safety considerations

It’s important to note that propane heaters can be potentially dangerous if not installed and maintained properly. Never attempt to install or repair a propane heater yourself. Always hire a trained professional to handle these tasks. Additionally, ensure that your propane tank is kept in a well-ventilated area, away from any potential sources of ignition.

Electric Heaters

Electric heaters are becoming increasingly popular due to their energy-efficiency and relatively low cost of installation. They work by using electric heating elements that warm up the water as it passes over them, making them a quiet and reliable option for households with small children. The downside to electric heaters is that they take longer to heat up the water and can be more expensive than gas heaters over the long run, but they’re a great option if you’re looking for something that’s easy to install and maintain.

How Electric Swimming Pool Heaters Work?

Electric swimming pool heaters work by using an electrical current to heat the water. This type of heater is typically installed near the pool’s filter system, and water is pumped through the heater. As the water passes through the heater, it is heated and then returned to the pool. Electric pool heaters are usually very easy to operate. You set the desired temperature and the heater will do the work for you. Unlike with gas heaters, you don’t need to worry about running out of fuel or fluctuating propane costs.

One of the main advantages of electric pool heaters is their efficiency. Unlike other forms of pool heating, electric heaters lose very little heat as the water is circulated. This means that they are both quick to heat up your pool and able to keep the water temperature consistent. Another advantage of electric pool heaters is that they tend to be cheaper to install than heaters that require gas lines or propane tanks, and they don’t produce any emissions.

While electric pool heaters are great for many pool owners, they do have some downsides. One of the main cons of electric pool heaters is that they can be expensive to run. The actual cost of running an electric pool heater will depend on factors such as the size of your pool and the air temperature, but it’s worth noting that these heaters can be a bit of an energy hog. Additionally, electric heaters tend to be slower to heat up than gas heaters, so they may not be the best choice if you’re looking to quickly warm up your pool before a party or event.

Another thing to consider if you’re considering an electric pool heater is that they usually require more maintenance compared to other types of pool heaters. This is because the heating element inside the heater can become corroded over time, which can reduce the efficiency of the heater. This means that you will need to periodically clean your electric pool heater to get it working at its optimal level.

Solar Heaters

If you’re looking for an environmentally-friendly option to heat up your pool, solar heaters might be right up your alley. They work by harnessing the power of the sun to warm up your pool water, making them one of the most cost-effective and eco-friendly options on the market. The only downside to solar heaters is that they rely on consistent sunlight to work properly- if you live in an area with limited sun exposure or have a lot of cloudy days, you may need to supplement your solar heating system with another type of heater to maintain a consistent water temperature.

How do Solar Swimming Pool Heaters Work?

Solar swimming pool heaters work by circulating pool water through a solar collector, which is typically installed on your roof or near your pool. The collector is made up of a series of tubes or panels that are designed to absorb the sun’s heat and warm up the water that passes through them. Once the heated water has circulated through the collector, it is then returned to your pool, thereby warming up your entire pool gradually without any additional cost.

Pros of Solar Swimming Pool Heaters

One of the biggest advantages of using a solar swimming pool heater is that it is a much more eco-friendly solution than traditional gas or electric heaters. You reduce your carbon footprint and contribute to the preservation of our natural resources.

As there are no fuel or electrical costs associated with solar pool heating, you will end up saving a lot of money on your utility bills.

Cons of Solar Swimming Pool Heaters

While there are many benefits to using a solar swimming pool heater, there are also certain drawbacks to keep in mind. For starters, these heaters are not suitable for use in all climates. If you live in an area where sunlight is scarce, you may not experience the same level of heating as someone who lives in a sunnier location. Additionally, the initial upfront cost of buying and installing a solar swimming pool heater can be relatively high, but this is often offset by the long-term savings.

Taking Care of Your Solar Swimming Pool Heater

One important factor to keep in mind is that solar swimming pool heaters require regular maintenance to operate optimally. Keeping the panels or tubes clean from dirt, debris, and leaves is crucial to ensure maximum absorption and heat transfer. Additionally, it’s essential to keep the pool water chemically balanced and ensure that your heater is installed and tested by trained professionals.

Heat Pumps

Heat pumps are a relatively new type of pool heater that use electricity to draw in warm air surrounding the pool and transfer it to the water. Most air-source heat pumps will shut down when temperatures are close to 55 degrees. These pumps work well for heating pools in Las Vegas since the temperatures do not typically drop below that. They’re incredibly energy-efficient and effective at maintaining a consistent water temperature, but they do tend to be more expensive than other types of heaters. If sustainability is a top priority for your family and you’re willing to make a long-term investment in your pool, a heat pump could be a great choice.

How do heat pumps work?

Essentially, a heat pump works by extracting heat from the surrounding air and using it to warm up the water in your pool. The process starts with the heat pump’s evaporator coil absorbing heat from the air. The absorbed heat is then compressed and transferred to the heat exchanger, where it is released into the water, warming it up in the process. The cooled-down air is then released back into the atmosphere, and the cycle begins again. The heat pump can maintain water temperatures up to 95 degrees Fahrenheit, depending on the model and climate conditions.

Advantages of using swimming pool heat pumps

One of the biggest advantages is that they are energy-efficient. Unlike traditional pool heaters that rely on gas or electricity to generate heat, heat pumps use energy from the air, making them more environmentally friendly and cost-effective. Heat pumps are also ideal for owners who want to use their swimming pools for extended periods. They can keep the water warm for longer, even during periods of cold weather when a gas or electric heater would be ineffective.

Downsides of using swimming pool heat pumps

One of the most notable disadvantages is that they take longer to heat up the water compared to other heating systems. If you are looking to heat your pool quickly, say for a spontaneous pool party, then a heat pump may not be the best option for you. Additionally, heat pumps may struggle to generate enough heat in areas that experience extremely cold temperatures. If you live in a location with frequent sub-zero temperatures, then you may want to consider a gas or electric heater instead.

Another important factor to keep in mind when using swimming pool heat pumps is their installation and maintenance. Swim pool heat pumps are complex systems that require professional installation and maintenance. Make sure to work with reputable installers and follow the manufacturer’s guidelines for maintenance. This will help avoid costly repairs and ensure that your heat pump is running efficiently.

Solar Blankets:

With outdoor pools, almost 75% of the heat lost is from evaporation. This is where having a solar blanket can be useful. Keeping a solar blanket on the pool will reduce evaporation and prevent heat loss. Solar blankets do not work well in extremely cold climates, but are perfect for Las Vegas and keeping the water warm into the cooler winter evenings.

Solar Pool Heaters:

One thing Las Vegas has is plenty of sunshine, so solar-powered devices are popular. Solar power heaters are both efficient for keeping the pool warm and affordable. These heaters work by pumping pool water through the filter, then through solar collectors where it gets heated. The warm water returns to the pool.

Install a Windbreak

During winter, the winds can be harsh and can significantly affect your pool’s temperature. By installing a windbreak, you can protect your pool from the wind and keep it warm. A windbreak can be as simple as planting a tall hedge or installing a fence around your pool. This will block the wind and reduce heat loss caused by wind chill.

Electric Resistance Heaters:

These heaters run completely on electricity. Many pool owners like this option because you do not need to install any tanks or lines. The downside is that relying on electricity costs money. Electric heaters are also more expensive to install than gas heaters. Your pool water will be warm year-round, but you will definitely see an increase in those monthly utility bills. Once the pool reaches the desired temperature, the pump does not need to work as hard, so it will become more energy-efficient at that point.


There are several options for keeping the pool warm in a Las Vegas winter. It may not get too chilly, but for those used to the heat, any drop in temperature is felt. Keeping the pool heated means you get more from your investment and you can swim long after the sun goes down. With a heated pool, you never have to worry about diving into frigid waters.
