This is a direct fix when a Raypak heater is not working at full output due to internal heat transfer failure.\u003c\/p\u003e\u003cp\u003eThis tube bundle kit is the internal assembly that carries water through the heated section of the heater in Model 406A polymer cupronickel configurations. When it becomes restricted, corroded, or compromised, the heater can still fire but will struggle to deliver usable heat. Replacing it restores the core heat transfer path and overall performance.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeater fires but water temperature barely increases\u003c\/li\u003e\n\u003cli\u003eInternal leaks or moisture buildup inside the cabinet\u003c\/li\u003e\n\u003cli\u003eScale or corrosion inside the exchanger during inspection\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 combustion heat into circulating water through the internal tube bundle assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for Raypak Model 406A polymer cupronickel systems.
