This is a common root cause when a Raypak heater is not working efficiently even though the burner side still appears normal.\u003c\/p\u003e\u003cp\u003eThis tube bundle carries water through the internal heat transfer section of the C-R405A ASME pool heater. When the bundle becomes restricted, corroded, or starts leaking, the heater loses efficiency and internal damage can spread fast. Replacing it restores the core water path where combustion heat is transferred into the pool water.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeater runs but recovery time is much slower than normal\u003c\/li\u003e\n\u003cli\u003eInternal water leakage develops 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 core heat transfer failure\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat this part does:\u003c\/strong\u003e It transfers combustion heat into circulating water through the internal tube bundle assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for the Raypak C-R405A ASME pool heater.
