Can High Efficiency Furnace Vented Through Chimney

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

Can high efficiency furnace vented through chimney.

To combat this issue a high efficiency condensing furnace uses pvc pipes to extract the acidic water from your home. But it is not advisable. Additionally how do you seal furnace exhaust to chimney. I think don t it is possible to vent a 95 efficiency furnace up through an existing chimney.

I would be very leary of a hvac contractor would not do this. They include a second heat exchanger that reclaims additional heat from the system s exhaust gases before they are vented away. Conventional furnaces use only one they use a two stage process. High efficiency furnace venting uses two heat exchangers.

The heater pipe is normally level and moderately short. These are connected to the furnace and routed out to the side of your home. Sometimes we see multiple appliances using the same flue vent system for multiple appliances but this isn t always a possibility. The condition of the chimney is a factor because new super efficient gas furnaces do not vent up the chimney.

Brush away any dirt or dust from the area around the furnace vent that you will be sealing. You may want to look into simply having the pvc intake and exhaust pipes for the furnace rerouted to go through a sidewall in your basement to the exterior. The efficiency rating of a furnace is called afue annual fuel utilization efficiency. That depends on whether you have a standard efficiency or a high efficiency furnace.

The venting system is installed at the same time as your high efficiency furnace. Two depending upon where the inlet for furnace combustion air intake pipe is located in relation to the fireplace chimney it could pull fireplace combustion gases and smoke into the furnace. Can your new furnace be vented through the chimney. In fact we almost always recommend against it if you have an older chimney and a new high efficiency furnace.

I believe high efficiency furnances must be vented horizontally through a wall. You need to make sure your furnace is venting properly.

For these reasons exhaust from a condensing furnace should never be vented through a standard chimney.

They are vented outdoors horizontally through a wall by a small plastic pipe. Also the acidic elements in the exhaust can damage unprotected chimney bricks and mortar. I have not heard of high efficieny only lasting 10 13 years. How new furnaces vent.

Condensing gas furnaces achieve their high levels of efficiency by adding another step to the fuel burning and venting process. The exhaust gas is too cool for it to rise. If your furnace has an afue rating of 90 percent or above it will have a flue pipe that goes out of the side of your house. Traditional gas fired forced air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes or chimneys.
