Chlorinated polyvinyl chloride (CPVC) first made its way into the world of venting systems in the residential market. Recently, CPVC has been used to vent Category IV high-efficiency boilers. While it can cost up to 20 percent less than stainless steel, those specifying venting systems should consider other differences that may impact boiler efficiency and present potential safety hazards.
