This is a direct repair when a Raypak heater is not working at full output because the internal heat-transfer section is failing.\u003c\/p\u003e\u003cp\u003eThis tube bundle carries water through the heated section of the P-R405A pool heater so combustion heat can move into the system. When the bundle becomes restricted, worn, or starts leaking internally, the heater can still fire but will struggle to deliver usable heat. Replacing it restores the core exchanger-side water path.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeater fires but water temperature rises slowly\u003c\/li\u003e\n\u003cli\u003eInternal leaks or moisture buildup appear in the exchanger section\u003c\/li\u003e\n\u003cli\u003eScale or corrosion is found during teardown\u003c\/li\u003e\n\u003cli\u003eRaypak heater troubleshooting points to exchanger inefficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat this part does:\u003c\/strong\u003e It transfers heat into circulating water through the internal tube bundle assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for the Raypak P-R405A pool heater.
