This is a direct repair point when a Raypak heater is not working efficiently because the internal heat-transfer section is failing.\u003c\/p\u003e\u003cp\u003eThis ASME copper tube bundle is the internal heat-transfer assembly for compatible 336A heaters. It carries water through the heated section so combustion heat can move into the system effectively. When the bundle becomes restricted, worn, or starts leaking, heater output drops and larger internal repairs can follow.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeater runs but water temperature rises slowly\u003c\/li\u003e\n\u003cli\u003eInternal 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 forms the internal tube bundle that transfers heat into circulating water inside the heater.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for Raypak 336A ASME heaters.
