Venting High Efficiency Furnace Through Wall

Don t confuse direct vent heating equipment with the through wall venting and air intake of high efficiency boilers and furnaces.

Venting high efficiency furnace through wall.

This high efficiency venting system must be installed when you install the new furnace. If you are venting a high efficient furnace with the pvc piping you can go through a roof or wall. They include a second heat exchanger that reclaims additional heat from the system s exhaust gases before they are vented away. Should my furnace flue pipe go through the roof or the side of the house.

Condensing gas furnaces achieve their high levels of efficiency by adding another step to the fuel burning and venting process. If it went out the chimney it would leave more headroom. It could either go out the unused walled in chimney that the oil furnace was vented through or they could cut a hole in the concrete block wall and vent it out the side of the house. That depends on whether you have a standard efficiency or a high efficiency furnace.

Both types of heating systems can vent horizontally through a building wall but the exhaust products of high efficiency or condensing boilers and furnaces are generally cool and have different venting and combustible clearance specifications. So which type of venting system should your furnace have. The basement ceiling is about 6 1 2 or 7 feet high. If your furnace has an afue rating below 90 percent it will most likely have a flue pipe that goes up through your roof.

You need to make sure your furnace is venting properly. To combat this issue a high efficiency condensing furnace uses pvc pipes to extract the acidic water from your home. These are connected to the furnace and routed out to the side of your home. It is easier to go through the wall next to the furnace and makes it a lot easier to deal with.

To avoid this problem high efficiency furnace venting requires the use of pvc pipes instead of metal pipes to remove the acidic condensate from your home. These pvc pipes are connected to the furnace and expelled outside.
