High Efficiency Furnace Venting Through Wall

If your furnace has an afue rating below 90 percent it will most likely have a flue pipe that goes up through your roof.

High efficiency furnace venting through wall. I believe high efficiency furnances must be vented horizontally through a wall. The efficiency rating of a furnace is called afue annual fuel utilization efficiency. The difference is that a power vent water heater pulls in combustion air from the space. So which type of venting system should your furnace have.

I would be very leary of a hvac contractor would not do this. I think don t it is possible to vent a 95 efficiency furnace up through an existing chimney. One of the most important safety features of gas condensing systems is furnace sidewall venting. Here are some good venting practices.

It uses a venting system to extract that heat before venting. Read more elaboration about it is given here in respect to this can a high efficiency furnace vent through a chimney. I have not heard of high efficieny only lasting 10 13 years. 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.

The exhaust gas is too cool for it to rise. 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. However these combustion gases contain residual heat that is lost through the ventilation.

If you decide to install this type of heating system take extra precautions to make sure all ventilation systems are properly placed and working correctly. The most efficient furnace units available today are gas condensing models which can achieve efficiency ratings of 90 or above. 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. Instead both systems typically expel exhaust through a pipe that runs outside through an exterior wall.

A conventional furnace vents these combustion gases through a vertical exhaust system that is attached to the furnace. Venting for high efficiency gas furnaces assembly. Don t confuse direct vent heating equipment with the through wall venting and air intake of high efficiency boilers and furnaces. A high efficiency condensing furnace can achieve efficiency ratings of 90 or above.

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. You can capture that heat with a high efficiency condensing furnace.
