Benefits of Pool Heaters

  • Extended Season: Enjoy your pool or spa for longer periods, even as temperatures drop.
  • Consistent Comfort: Maintain a steady, comfortable water temperature.
  • Optimal Chemical Performance: Heaters help circulate chemicals effectively, keeping your water clean and sanitized. 

Types of Pool Heaters

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

Accessories for Efficiency

Covers: Prevent heat loss with pool covers, safety covers, or solar rings.
Thermometers and Timers: Monitor temperature and reduce energy use with timers.
Protective Covers for Heaters: Extend heater life and protect against weather or pests.

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!
