There is a five-year limited warranty for Steffes heaters that covers the heating system parts, as of 2015. Steffes Corporation heaters were the first electric thermal storage heating units designed and made in the United States. The heating systems have a track record of high reliability and long life expectancy.
Steffes heating units do not need routine maintenance, certification or yearly cleaning. A unit may last more than 20 years, depending on its operating environment and whether the proper size was installed. Product technical support meets customer needs during normal business hours and after hours by arrangement. Homeowners needing unit repair or service should communicate with their local Steffes-authorized dealer or installer.
