Heat-transfer failures here usually show up as slow recovery, moisture in the cabinet, and a heater that feels weaker every season.\u003c\/p\u003e\u003cp\u003eThis tube bundle is the internal heat-transfer assembly for compatible C-R265A and C-R266A ASME heaters. It carries water through the heated section so the unit can move combustion heat into the system efficiently. When the bundle is scaled, damaged, or leaking, heater performance drops fast and continued use can lead to larger internal repairs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSlow heating and reduced overall output\u003c\/li\u003e\n\u003cli\u003eInternal exchanger leakage or moisture buildup\u003c\/li\u003e\n\u003cli\u003eScale or wear found in the bundle during service\u003c\/li\u003e\n\u003cli\u003eNeed to fix a Raypak heater with 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 C-R265A and C-R266A ASME heaters.
