Stelrad provides robust warranty coverage across its extensive heating product portfolio to protect customers against manufacturing, assembly, or material defects. Most standard horizontal steel panel radiators come backed by a comprehensive 10-year warranty, while specialized models like the Softline range feature an extended 15-year warranty. Other selective product lines carry a 5-year warranty. For radiators installed in areas prone to high humidity—such as bathrooms, wet rooms, or kitchens—standard steel panel warranties are typically limited to twelve months unless specified otherwise by particular product lines like the Compact XP range, which maintains an extended warranty.
