Tired of closing your pool as soon as the weather gets cold? Are you looking to extend your swimming season by more than just a few weeks? Gas Heaters are a great way to quickly heat your water, and allow you to enjoy your pool for months past the end of swimming season! Great for in-ground pools in every type of climate, Gas Heaters are designed to extend your swimming into the early spring and late fall by efficiently heating your water to a comfortable swimming temperature. Gas Heaters run on either propane or natural gas, depending on the model, and are very efficient energy users, running at up to 80-95% efficiency. Purchasing a Gas Heater will give you months of warm water even during cold weather, and help you and your family spend more time in the pool than ever before!

Gas Heaters are some of the most effective and powerful pool heaters on the market. These types of heaters work by using either natural gas or propane as fuel to heat the water before returning the water to the pool. All of Leslie’s Gas Heaters use hot surface ignition, meaning they do not use a pilot light. Pilot lights can be a hassle to start, and run the risk of being extinguished in wind or rain. These types of heaters are very easy to use, and require little maintenance.

Gas Heaters are designed to raise the temperature of a pool up to the ideal swimming range, between 78 – 82 degrees Fahrenheit, and because of this, most Gas Heaters are capable of increasing the water temperature 30 degrees or more. Pools come in all shapes and sizes, and require varying amounts of heat in order for the water to reach comfortable temperatures. Our Gas Heaters range from 125K BTUs, ideal for small pools, and up to 400K BTUs, great for large pools. Pool owners in cold climates that see low temperatures for much of the early spring and late fall spring will want to consider a Gas Heater to help make their pool fun and enjoyable for much of the year.

Not only do Gas Heaters save you money by running at up to 95% efficiency, they are also designed to meet Low NOx Emissions Requirements. Nitric Oxide (NOx) is a pollutant known to cause smog and acid rain when produced in large quantities. All of the Gas Heaters that Leslie’s offers proudly meet or exceed Low NOx Emissions Requirements, meaning you are getting the most advanced, eco-friendly heaters available that will keep your pool and your family safe and healthy.

Heating your water is vital to enjoying your pool and extending your swimming season, but without retaining the heat in your pool using a solar cover, much of the energy that is used warming the pool will dissipate into the air. Using a solar cover along with a Gas Heater can save you as much as 50% of the cost of energy it takes to heat your pool. Combining a solar cover with a Gas Heater will heat your pool quickly, and will keep the pool warm long into the night, as well as later into the swimming season.
