R L Deppmann

R.L. Deppmann is a heating equipment supplier operating from Brecksville, Ohio, with additional locations in Cleveland, Detroit, Grand Rapids, and Saginaw. The business serves contractors across Northern Ohio and Michigan, specializing in hydronic heating systems, boilers, and related mechanical equipment. Founded in 1927, the company has maintained continuous operations for nearly a century, evolving from a traditional supply house into a comprehensive solutions provider for professional contractors.

What distinguishes R.L. Deppmann is their contractor-only distribution model and deep technical specialization. The company stocks pumps, Variable Frequency Drives, glycol solutions, and snowmelt design systems, offering equipment that typical retail suppliers do not carry. Their project gallery showcases complex installations including data center glycol applications, and their education division provides factory classes and training opportunities for contractors seeking to expand their technical knowledge. The business has earned recognition as a Top Workplace for seven consecutive years, reflecting internal culture alongside external service commitments.

Customer testimonials highlight specific instances of responsiveness, with one account describing a technician named Brad who met a contractor at their Bridgeport location on a Sunday in January to resolve an urgent boiler issue for an elementary school. The reviewer noted the technician tested the product before departure, enabling same-day repairs. Another testimonial emphasizes the company's in-depth component and system knowledge, suggesting technical competence across their product lines.
