The compact EZ Series is designed to speed replacement of conventional storage-tank water heaters, offering a Uniform Energy Factor of 0.96 and a 25-year warranty. Two types of high-grade stainless steel in the heat exchangers offer resistance to heat shock and cracking while extracting latent heat from the combustion process, resulting in resistance to corrosion and scale buildup. In addition, a Steady Btu (SBtu) Mode eliminates concerns over high incoming water temperatures.
