The Ginius from ACV Triangle Tube is a high-performance indirect water heater with the Picanto heat exchanger design that allows for higher pressure ratings and higher output. In addition, the design offers less resistance to boiler flow than conventional coil heat exchangers. The heat exchanger and the outer tank are constructed entirely of passivated stainless steel to ensure long service life. The tank is available in 35-, 45-, 55- and 65-gallon sizes, including the 65-gallon Flex tank that features a dual heat exchanger configuration designed for super high-output or for use with multiple energy sources. It is approved for up to 80 psi boiler pressure with ideal continuous hot water performance. 856-228-8881; www.triangletube.com.
