"August 29, 2000 Teledyne Laars, an Allegheny Teledyne Incorporated company, recently acquired the assets of Randolph, Massachusetts-based Trianco-Heatmaker, Inc., manufacturer of high efficiency gas- and oil-fired boiler and water heating products. “Trianco-Heatmaker’s high efficiency, sealed combustion systems add to our heating technology base,” says Wendy Howells, vice president of Teledyne Laars heating systems. "
In fact, they still make the “heatmaker” under a different name and the parts are interchangeable and they honor any existing warranties, have manuals etc. and a nice customer service department. I just had my daughter’s Trianco serviced under a Laars warranty.
