{"product_id":"ideal-esprit-main-heat-exchanger-refurbished-177566","title":"Ideal Esprit Main Heat Exchanger – Refurbished | Part No. 177566","description":"\u003cp\u003eThe main heat exchanger in an Ideal Esprit boiler is the core thermal component — the stainless steel or copper assembly through which combustion gases transfer their heat energy into the primary water circuit. When this component deteriorates through corrosion, scaling, or thermal fatigue cracking, the boiler's efficiency falls progressively, flue temperatures rise above normal parameters, and the boiler may begin generating fault codes relating to high limit thermostat trips or combustion analysis failures. In advanced cases, pinhole leaks in the exchanger body allow flue gases to enter the water circuit — a serious safety concern requiring immediate rectification. The \u003cstrong\u003eIdeal Esprit Main Heat Exchanger (Part No. 177566)\u003c\/strong\u003e is the correct OEM replacement for restoring full thermal efficiency and safe operation.\u003c\/p\u003e\n\n\u003cp\u003eThis is a professionally refurbished genuine Ideal heat exchanger. Each unit undergoes a thorough inspection of the exchanger body, flow and return manifolds, flue connections, and all gaskets and seals — with worn or compromised components replaced as required. The assembly is then pressure-tested at working pressure to confirm structural integrity and complete leak-tightness across all joints before dispatch. You receive full OEM-spec thermal output and safety performance at a significant saving over a new replacement unit.\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;\"\u003eIdeal Esprit 24\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e41-516-10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eIdeal Esprit 30\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e41-516-11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eIdeal Esprit Eco 24\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e41-516-14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eIdeal Esprit Eco 30\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e41-516-15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eIdeal Esprit Eco 2 30\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003e41-516-17\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.
