De Dietrich 7619579 na izolacja

This insulation panel, listed under the boiler insulation category, is a replacement part for the casing of a De Dietrich appliance. Parts of this type are fixed to the boiler housing and serve to retain heat within the combustion chamber, reducing heat loss and protecting surrounding components from excessive temperatures. Because the insulation sits against the boiler body, its shape and thickness must match the original exactly to prevent cold spots, condensation, or damage to the casing. Insulation panels degrade over time due to repeated heat cycling, and can become brittle or lose their thermal efficiency. When selecting a replacement, the correct part is identified by the appliance model and the specific position the panel occupies on the boiler – not by a technical rating. A panel that does not fit precisely can leave gaps that allow heat to escape or create local overheating. For this reason, it is essential to verify the part number against the original insulation before fitting. The item is referenced under manufacturer codes 7619579 and 336.778.012. As with all boiler casing components, ensure that the appliance is cold and depressurised before handling or replacing the insulation.
