Triangle Tube is best known for two things: feats of hydronic innovation and incredibly efficient products. If you are looking for those qualities in your hot water boiler, the Keystone certainly fits the bill. The Keystone is a high-efficiency, condensing boiler for large spaces. The condensing technology behind the Keystone will capture and reuse gaseous heat that escapes traditional boilers. Stainless steel construction of the heat exchanger and an internal condensate trap will protect the KS 750 from corrosion. The Keystone's modulating burner scales heat production based on your needs and reduces unnecessary energy consumption. All told, the Keystone is an incredibly reliable and efficient water heating solution.

Should you experience an issue during the installation or the initial startup of the unit, please do not contact the manufacturer.
