De Dietrich 82290030—kompletny dział specjalny

De Dietrich 82290030 is listed as a complete special section in the heat exchangers category. The manufacturer codes are 82290030 and 336.709.015. Parts of this type are the heat exchanger that transfers heat from the flue gases to the system water. In boilers that also produce domestic hot water, a secondary plate heat exchanger is often integrated. Turbulators are fitted inside the flue gas passages to slow the gas flow and improve heat uptake. Such heat exchangers are selected based on model‑specific dimensions and connection patterns, the number of plates or gas‑ways, the material (commonly stainless steel, copper, or aluminium alloy), and the gasket type. When inspecting or replacing a heat exchanger of this class, typical failure points include scaling on the water side, soot deposits on the gas side, gasket leaks, and, in condensing boilers, corrosion where condensate collects.
