High Efficiency Gas Furnace Vent Installation

Energy star has found that new furnaces often do not perform to their rated efficiency with.

High efficiency gas furnace vent installation. This heat exchanger extracts extra heat from the combustion gases that would otherwise be wasted. This allows your furnace to get more heat out of the gas that it consumes. 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. The installation for this natural type is quite easy with modest cost.

Traditional gas fired forced air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes or chimneys. Goodman 96 afue variable speed gas furnace has 2 pipe direct vent to ou. High efficiency gas furnaces take advantage of the fact that combustion gases contain heat and they send those gases to a second heat exchanger. A conventional furnace vents these combustion gases through a vertical exhaust system that is attached to the furnace.

When a furnace is installed so that supply ducts carry air circulated by the furnace to areas outside the space containing the furnace the return air shall also be handled by a duct s sealed to the furnace casing and terminating outside the space containing the furnace. Most us homes have a gas furnace while some of the more northern states use oil and many rural areas have wood burning furnaces. However without a quality installation the furnace may never deliver its expected energy. A high efficiency furnace uses a different type of venting system because it extracts the heat that remains in those combustion gases before venting the resultant mixture of water and carbon dioxide.

When the vent is withdrawing air from the house it expels the gas outside through the vent. Proper installation of a high efficiency gas furnace requires attention to many details and interconnecting systems. Heating capacity sizing consideration for duct distribution systems gas piping vent systems provision for combustion air flue gas condensate disposal electrical. It should be done.

However there could be reasons to change based on your house size location and energy bills. A gas fired furnace for installation in a residential garage. A conventional natural gas furnace will vent the dangerous combustion gases through a simple vertical exhaust system that is attached to the furnace. This structure generally uses the furnace vent pipe through roofbecause the b venting pipe is designed in vertical manner.
