Rear insulation De Dietrich 7623993

The rear insulation is a thermal barrier installed at the back of the boiler to minimize heat loss and improve energy efficiency. This insulation layer helps maintain consistent operating temperatures and reduces the workload on the heating system. Over time, insulation can degrade or become damaged, leading to increased fuel consumption and uneven heating. Replacing the rear insulation is a cost-effective way to restore your boiler's performance. This component is typically made from high-temperature resistant materials and is designed to fit snugly within the boiler casing.
