Teledyne boilers are manufactured by the LAARS Heating Systems Company, which is headquartered in Rochester, New Hampshire. LAARS-manufactured boilers utilize natural gas or liquid propane for the heating of domestic hot water and closed loop hydronic systems, according to the company's website.
Teledyne Technologies acquired LAARS Engineering in 1966, which eventually became the LAARS Heating Systems Company, according to the Building Intelligence Center. In 2005, the LAARS Heating Systems Company was purchased from Teledyne by the Bradford White Corporation, a privately-owned American manufacturer of residential and commercial water heaters. As a subsidiary of Bradford White, LAARS continues to manufacture both residential and commercial-grade hot water boilers.
