The tube bundle is the heart of your Raypak heat exchanger. It transfers heat from the burner into the pool water while keeping the combustion gases and water completely separate. Over time the tube bundle can fail due to corrosion, poor water chemistry, electrolysis, scale build-up or freeze damage. Replacing the tube bundle or complete heat exchanger assembly restores heating performance and is often considerably more economical than replacing the entire gas pool heater. Choose the Correct Option Tube Bundle This option is ideal if your existing manifold headers are still in good condition and can be reused. Residential models include new Seal O-Rings. Premium models include new Seal Gaskets. Perfect when replacing only the internal tube bundle. Complete Residential Heat Exchanger Includes: Cupronickel Tube Bundle New Seal O-Rings Black Capron Manifold Headers Suitable for Raypak 200, 280, 350 and 430 Residential heaters. Complete Premium Heat Exchanger Includes: Cupronickel Tube Bundle New Seal Gaskets Bronze Manifold Headers Suitable for Raypak 280 Premium and Raypak 430 Premium heaters. Common Signs Your Heat Exchanger Has Failed Water leaking from inside the heater. Pinhole leaks in the tube bundle. Corrosion inside the waterways. Reduced heating performance. Green staining around the heat exchanger. Freeze damage. Cracked or damaged manifold headers. Frequently Asked Questions What is the difference between Residential and Premium heaters? Residential heaters use black Capron manifold headers, while Premium heaters use heavy-duty bronze manifold headers. What is a tube bundle? The tube bundle is the cupronickel core of the heat exchanger. It is supplied with the required seals so your existing manifold headers can be reused if they remain in good condition. When should I purchase the complete heat exchanger? Choose the complete heat exchanger if your existing manifold headers are cracked, damaged, warped or heavily corroded, or if you simply prefer to replace the entire assembly. Which heat exchanger suits my Raypak 280 or 430? Both the 280 and 430 heaters were manufactured in Residential and Premium versions. Please ensure you select the correct model before ordering.
