The forte of the Aldrich Company has always been to only manufacture products of the highest quality and design, by using the finest materials available and employing loyal craftsmen with the skills and aptitude necessary towards this end. We outsource no sub-assemblies and we procure only domestic steel and tubing to fabricate our pressure vessels. All Aldrich boilers and water heaters are constructed and stamped to Section IV of the ASME code and registered with the National Board of Pressure Vessel Inspectors.
