Founded in 1923, Oswald Supply is family owned and operated through four generations. Founder, Henry Charles Oswald built the business as a Boiler supply company that soon became the go-to resource for the heating trades in NYC. Keep in mind, at this time, NYC was incinerating garbage, not compacting it as we do now. Incinerators and boilers are both very similar in design, which is why the two product lines were established as Oswald Supply mainstays and are still our top selling items today, 100 years later!
