Pool Heaters

Enjoy your pool year-round with a high-quality pool heater from Pool Supply Unlimited. We carry top brands like Raypak, Pentair, Jandy, Hayward, Lochinvar, and Trane. Offering gas and electric pool heaters, including low NOx models, high-altitude units, and compact heaters for above-ground pools and spas. 

Types of Pool Heaters

Natural Gas & Propane Heaters: Quick, efficient heating for any climate.
Electric Heaters: Best for smaller pools or spas; installation requires a standard or 220v electrical connection.

Heat Pumps vs. Pool Heaters

Choosing between a pool heater and a heat pump depends on your climate and heating needs. Pool heaters, powered by natural gas, propane, or electricity, are ideal for colder climates and fast heating. Heat pumps offer energy-efficient heating for milder climates where temperatures stay above 50°F.

Choosing the Right Pool Heater

When selecting a heater, consider size, energy efficiency, noise levels, and your local climate to find the perfect fit. Pool Supply Unlimited not only offers the best pool heaters but also a wide range of pool supplies to keep your system running smoothly year-round. Let us guide you to the ideal heating solution tailored to your pool and budget. Shop now or contact us for expert advice!
