{"product_id":"vaillant-main-heat-exchanger-refurbished-065179","title":"Vaillant Main Heat Exchanger – Refurbished | Part No. 065179","description":"\u003cp\u003eThe main heat exchanger in a Vaillant boiler is the critical assembly where the heat generated by combustion is transferred efficiently into the primary water circuit. Part No. 065179 is the main heat exchanger used across a range of older Vaillant Turbomax and ecoMax combi and system boilers — a copper tube-and-fin assembly that over time is susceptible to pinhole corrosion, limescale-induced hotspots, and gasket degradation at the flow and return connections. When this exchanger begins to fail, the boiler typically experiences increasing high-limit thermostat trips, reduced heating output, and in advanced cases, trace water contamination in the flue gas. The \u003cstrong\u003eVaillant Main Heat Exchanger (Part No. 065179)\u003c\/strong\u003e is the correct OEM replacement for restoring full thermal output and safe, efficient operation.\u003c\/p\u003e\n\n\u003cp\u003eThis is a professionally refurbished genuine Vaillant main heat exchanger. Each unit is fully inspected — the exchanger body, tube stack, flow and return manifolds, and all gaskets and seals are assessed and replaced as required. Following refurbishment, the assembly is pressure-tested at working pressure across all ports and connections to confirm complete leak-free integrity before dispatch. You receive the same primary thermal performance as a new exchanger at a significantly lower cost.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCompatible Boiler Models\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003cth style=\"padding:8px;border:1px solid #ddd;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:8px;border:1px solid #ddd;\"\u003eGC No.\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eVaillant Turbomax Plus 824\/2 E\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e47-116-18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eVaillant Turbomax Plus 828\/2 E\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e47-116-19\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eVaillant Turbomax Plus 835\/2 E\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e47-116-20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eVaillant Turbomax Plus 837\/2 E\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e47-116-21\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eVaillant ecoMax 828\/2 E\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e47-116-30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eVaillant ecoMax 835\/2 E\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e47-116-31\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eVaillant ecoMax 837\/2 E\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e47-116-32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOEM Quality.
