Triangle Tube is an innovative company dedicated to providing unique stainless steel potable hot water products to the U.S. and Canadian markets. The core technology is the \"Tank-in-Tank\" product design, a name coined by Triangle Tube at the beginning of the 80\'s to describe a new type of indirect water heater that is capable of operating at high temperatures and withstanding the negative impact of liming. Since then, Triangle Tube has expanded its product offerings to include \"Tank-in-Tank\" direct-fired products ,complementary brazed plate heat exchangers and a swimming pool or spa heater.
