Vertical Domestic Hot Water Boilers

Superior Domestic Hot Water Boilers are high-quality indirect water heaters that are a creative solution for virtually any potable water application.

These vessels have an oversized indirect copper coil that provides substantial water volumes at a typical rise of 100°F.  An oversized 1.5 inch diameter copper coil of up to 90 feet long provides substantial water volumes when needed. This large diameter indirect water hearter is indirectly-fired, so the boiler water heats potable water inside the coil. This method is superior to direct-firing a coil, because it results in fewer hard water deposits being percolated out of the water. These indirect water heaters can be paired with a domestic hot water storage tank, or simply used to circulate domestic hot water through the building loop for instant hot water.

These boilers are ready-to-install packaged systems featuring a perfectly matched powerful and efficient burner/boiler combination. All necessary hot water boiler controls and secondary plumbing are in place and pre-wired, with the vessels easily fitting into difficult spaces.
