Every time a hot tap is opened, it transfers heat from the primary circuit to the domestic hot water circuit almost instantaneously — cycling through thousands of thermal events across a boiler's lifespan. Over time, limescale accumulation, thermal fatigue, and minor internal leaks gradually reduce its efficiency until hot water delivery becomes inconsistent, flow rates drop, or the boiler starts throwing fault codes. The \u003cstrong\u003eWorcester Bosch 20 Plate Heat Exchanger (Part No. 87161082120 \/ 448435)\u003c\/strong\u003e is the exact replacement required to restore full heating and hot water performance to your Worcester Bosch combination boiler.\u003c\/p\u003e\n\n\u003cp\u003eThis is a professionally refurbished genuine Worcester Bosch component. Each unit undergoes a thorough inspection, deep cleaning, and pressure testing process before being verified against original manufacturer specifications — giving you OEM-grade reliability without the new-part price tag. The \u003cstrong\u003e20-plate design\u003c\/strong\u003e provides an efficient heat transfer surface area, ensuring rapid and consistent hot water delivery exactly as the boiler was originally engineered to deliver. It fits directly into place with no modifications required, making for a clean, straightforward installation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCompatible Worcester Bosch Models\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"width: 41.2455%;\"\u003eCompatible Model\u003c\/th\u003e\n\u003cth style=\"width: 56.2945%;\"\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 41.2455%;\"\u003eWorcester CDI 35 COMBI\u003c\/td\u003e\n\u003ctd style=\"width: 56.2945%;\"\u003eDirect Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 41.2455%;\"\u003eWorcester CDI 40 COMBI\u003c\/td\u003e\n\u003ctd style=\"width: 56.2945%;\"\u003eDirect Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 41.2455%;\"\u003eWorcester Greenstar 35CDI FSN NG\u003c\/td\u003e\n\u003ctd style=\"width: 56.2945%;\"\u003eDirect Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 41.2455%;\"\u003eWorcester Greenstar 40CDI FSN NG\u003c\/td\u003e\n\u003ctd style=\"width: 56.2945%;\"\u003eDirect Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 41.2455%;\"\u003eWorcester British Gas 532i 32CDI FSN NG\u003c\/td\u003e\n\u003ctd style=\"width: 56.2945%;\"\u003eDirect Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 41.2455%;\"\u003eWorcester British Gas 537i 37CDI FSN NG\u003c\/td\u003e\n\u003ctd style=\"width: 56.2945%;\"\u003eDirect Replacement\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\n\u003cp\u003e\u003cstrong\u003eRefurbished to OEM Standards.
