Over 50 Years of Heat Innovation

For more than five decades, Raypak has shaped the standard for gas pool heating. From the introduction of the Gemini heater in 1974 —a breakthrough product that set Raypak’s reputation in motion—to today’s Digital Gas Pool & Spa Heater (206A–406A), our commitment to durability, serviceability, and real-world performance has made Raypak a cornerstone of the pool industry.

As we celebrate over 50 years of leadership in gas pool heating, we’re honoring where we’ve been, where we are today, and how we’re evolving to meet the standards of tomorrow.

Raypak’s journey in gas pool heating began with the Gemini heater, an innovative design introduced in 1974. It quickly made waves for its reliability, simplicity, and install-friendly engineering—a formula that would become our hallmark.

From the Gemini forward, Raypak built a reputation for equipment pool techs love working with and straightforward, durable construction. Our products thrive in real-world conditions and have an industry-leading longevity.

This foundation paved the way for what would become a defining chapter in our history: Raypak’s atmospheric gas heaters.

Today, Raypak proudly carries forward the legacy of producing the #1 atmospheric pool gas heater on the market—a position earned over decades of reliability and performance. Atmospheric heaters remain a favorite among pros for their simplicity, resilience, and ease of service.

This continued commitment reinforces our belief that longevity isn’t achieved by chance—it’s engineered.

We have been using the Raypak Atmospheric Heaters as our primary choice for a pool heater for over a decade and have no intention of changing. As a firm that performs new construction and service we consider the lifetime use of the equipment. The Raypak heater is incredibly tolerant of potential variables in gas and flow, easy to service if needed, and its simple design has proven itself as a heater that we watch stay in operation for up to twice the life of the competition. Our favorite line is after a decade in use when other heaters have quit. I could probably shoot an old Raypak, and it will keep heating. I once heard of a customer taking the burners out of their 20-year-old Raypak Atmospheric and making a wood fire in the bottom to get one more season out of it. Having installed and serviced every brand of heater we continue to prefer the Raypak Atmospheric wherever it is a viable option. – Kirk Lavery, Millennium Pool

Building on this legacy, the Digital Gas Pool & Spa Heater has become the trusted, pro-favorite workhorse for well over 20 years. Its service-friendly layout, consistent performance, and rugged design make it one of the most widely used heaters in the field.

Highlights of its evolution include:

• Advanced digital controls for precise, reliable operation
• Enhanced materials and coatings for superior durability
• Refined combustion and heat-transfer systems
• Installer- and technician-friendly access for faster service

This unit is not only trusted by pros and recognized by Forbes two years in a row for “Best Heater” (2023 and 2024), but it is also proven by decades of performance.

Just as we’ve done for more than 50 years, we’re adapting, advancing, and preparing for what’s next. From the Gemini to today’s Digital Gas models, from pioneering atmospheric heaters to preparing for a high-efficiency future, Raypak’s history is grounded in one simple idea: Build heaters that last.

Over 50 years later, that idea hasn’t changed—and neither has our commitment to the professionals who depend on our products every day.
