Insulating Gas Furnace Exhaust Pipe

The pvc pipes are used for air intake exhaust gas and to remove the corrosive condensation resulting from the combustion process.

Insulating gas furnace exhaust pipe.

The plastic gas furnace intake pipe can be insulated but any insulation strategy must include a vapour barrier on the outside. Traditional gas fired forced air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes or chimneys. To insulate your pipes follow these rules. Without this indoor air will permeate the insulation and condense internally against the pipe.

For hot water systems install electrometric or urethane rubber pipe insulation with a suggested minimum r value of 6 only on supply pipe. Other aspects of high efficiency furnace venting. This high efficiency venting system must be installed when you install the new furnace. How to insulate a metal flue pipe.

The flue is the metal tubing that extends up from the top of your gas furnace or water heater that carries the carbon monoxide gas from the heating unit to your. Insulating the walls and ceiling in a furnace room can reduce heating costs and make the furnace more energy efficient. In contrast modern high efficiency condensing furnaces exhaust much cooler gasses and need only plastic pipe materials such as pvc cpvc or abs for their exhaust vents some high efficiency furnaces also include a plastic pipe for intake area and all types.
