High Efficiency Furnace Exhaust Through Roof

The condition of the chimney is a factor because new super efficient gas furnaces do not vent up the chimney they are vented outdoors horizontally through a wall by a small plastic pipe.

High efficiency furnace exhaust through roof.

It uses a venting system to extract that heat before venting. You can capture that heat with a high efficiency condensing furnace. Traditional gas fired forced air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes or chimneys. 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.

Should my furnace flue pipe go through the roof or the side of the house. One side effect of removing that extra heat from combustion gases is that the combustion byproducts are cooled down and released in a liquid form in high efficiency furnaces. A high efficiency condensing furnace can achieve efficiency ratings of 90 or above. Read more elaboration about it is given here in respect to this can a high efficiency furnace vent through a chimney.

This allows your furnace to get more heat out of the gas that it consumes. So which type of. However these combustion gases contain residual heat that is lost through the ventilation. High efficiency furnaces produce high amounts of condensation moisture in the exhaust vent which is designed to run back into and through the furnace in order to drain out into either a floor drain or other approved draining system.
