Why Replace the Tube Bundle?
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.

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.

Professional Installation Recommended
Replacing a tube bundle or complete heat exchanger requires disassembly of the heater and reconnection of the water circuit. HeaterFix recommends installation by a qualified pool heater technician. While the heater is dismantled, it is also a good opportunity to inspect the bypass assembly, pressure switch, burner tray and ignition components to ensure reliable heater performance.
