Traditional gas-fired, forced-air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes, or chimneys. In contrast, contemporary high-efficiency condensing furnaces exhaust a lot cooler gasses and want purely plastic pipe materials—such as PVC, CPVC, or ABS—for their exhaust vents. PVC or ABS plastic piping is often used on high-efficiency heating and water heating … Read more
