Raypak 207A Digital Low NOx ASME Pool & Spa Heater

The Raypak Digital Low NOx ASME Gas Pool & Spa Heater (models 207A–407A) is a top choice for homeowners, service professionals, and commercial facilities that require efficient, flexible, and long-lasting performance. Named the #1 Pool Heater by Forbes in “Top 10 Best Pool Heaters”, this heater is engineered to deliver consistent heating power while meeting strict ASME commercial standards. With an input rate of 199 MBTU/h and 82% thermal efficiency, it provides reliable results for pools and spas of varying sizes while reducing operating costs.

Built for strength and durability, the heater features a corrosion-resistant galvanized metal cabinet, a copper or cupronickel fin tube heat exchanger, and bronze ASME headers. The straight tube design of the exchanger eliminates unnecessary bends and friction, extending the unit’s lifespan. Raypak’s exclusive ProTek Shield module adds another layer of protection by absorbing corrosive elements in both chlorinated and saltwater pools, ensuring the heat exchanger performs at its best for years.

The Digital Low NOx ASME series also incorporates a blower and gas valve system to maintain a clean, safe burn even when gas pressure fluctuates. This Low NOx certification meets additional safety standards and environmental regulations in states such as California, Texas, and Utah. Intelligent digital controls with a microprocessor-based thermostat make temperature management easy, and the system can be integrated into existing remote control setups for added convenience.

Whether upgrading an older heater or installing a new system, the sleek low-profile design, flexible installation options, and self-adjusting burner make the Raypak Digital Low NOx ASME heater one of the most trusted and versatile solutions on the market. Engineered for year-round use, it is equally effective in residential backyards or demanding commercial environments.
