Description

The Raypak 009218 336,000 BTU Natural Gas Pool Heater is a high-performance, premium-grade heating solution built to satisfy even the most demanding pool or spa systems. With a powerful 336,000 BTU heating capacity, it supports environments requiring exceptional thermal output—such as large backyard pools, resort installations, and heavy-duty aquatic facilities. Constructed from rugged materials, the unit incorporates cast-iron headers and bronze fittings, delivering strength, corrosion resistance, and long-term reliability even under heavy chemical loads and continuous operation. The internal heat exchanger uses finned copper tubing to maximize thermal transfer from the combustion chamber to the water. A built-in digital control panel allows precise temperature adjustment, real-time status tracking, and error code diagnostics to assist with rapid troubleshooting. For protection and system longevity, the heater also integrates an Unitherm bypass system and flow sensor, maintaining proper water movement and reducing the risk of condensation in low-flow scenarios. Installation is designed to be smooth and adaptable: the 009218 supports standard plumbing connections, includes access panels for maintenance, and is enclosed in a weather-resistant exterior for outdoor durability. Service technicians benefit from intuitive design, accessible components, and simplified diagnostics. Whether for upscale residential pools or demanding commercial applications, the Raypak PR336AENC49 Natural Gas Heater delivers tremendous capacity, structural resilience, control intelligence, and field service ease, making it a dependable and efficient choice for serious heating needs.

  • Very poor quality
We all know the lack of chlorine this year was an issue. My water never was murky we had multiple people using our pool there were no skin issues no burning eyes no issues whatsoever with anyone feeling that the pH could have been off neutral. Yet this heater’s Quality failed us within one year of being used. We replaced a heater that we used for 19 years. And yes it’s heater core failed. But I think that’s reasonable. The quality engineering on this product is substandard. I am highly skeptical if they will stand behind the materials they use and replace the part for me I will update this if they have a quality department that will stand behind Their manufacturing and engineering. ... show more
