Front insulation 24 kW Viessmann 7825502

Front combustion chamber insulation (insulation board) for Viessmann wall-mounted gas boilers with 24 kW power. Combustion chamber insulation plays an important role in boiler operation. It prevents heat loss, increasing equipment efficiency and saving fuel. Additionally, insulation protects surrounding components and housing elements from overheating, ensuring safe operation of the device. Technical specifications: Part numbers: 7825502, 956.280.001. Manufacturer: Viessmann (Germany). Name: Front insulation (Faserdammung vorn), also may be called combustion chamber insulation. Compatibility: Viessmann boilers with 24 kW power: Vitopend 100-W (type WH1B). Vitopend 100-W (type WHKB 25 kW). Material: High-temperature insulation material (fiber). Warranty: 6 months. Compatibility (Important!) This front insulation is designed for Viessmann Vitopend series boilers with 24 kW power (and some 25 kW models). For boilers of other power (e.g., 30 kW), the insulation part number will differ. Before purchasing, be sure to check the required part number in your boiler's documentation. ⚙️ Signs of malfunction and when to replace Thermal insulation has no electronic components and does not break in the usual sense, but over time it can deteriorate. Replacement is required for the following signs: Physical destruction: Insulation material crumbles, falls apart when touched, or has obvious through cracks and chips. Salting: When water leaks from the combustion chamber, the insulation becomes saturated with salts and loses its thermal insulation properties (becomes hard and brittle). Heat exchanger or combustion chamber replacement: During major boiler repair with replacement of key components, it is strongly recommended to replace the insulation with a new one, as the old one often becomes deformed.
