Does a gas furnace have a condensate drain?
Most furnaces will have at least 2 internal drains, typically one for the heat exchanger and one for the vent, usually at the inducer outlet or on the inducer housing. All condensate drains go into a trap. The condensate trap is absolutely mandatory for a high-efficiency gas furnace.
What is condensing gas furnace?
Condensing furnaces are high-efficiency furnaces with a secondary heat exchanger that condenses hot exhaust gases in order to extract the “waste” heat before it wafts up the chimney.
How much condensate does a gas furnace produce?
Typical high-efficiency furnaces will actually produce about 0.8 gallons per hour of condensate for a 100,000 input BTU furnace running constantly. Since furnaces do not run constantly, this amount of condensate is reduced even more.
Do high efficiency furnaces produce condensate?
Plugged condensate drains. 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.
How long do condensing furnaces last?
Average Furnace Lifespan Although some furnaces can last more than 40 years (extremely rare), the average life of a furnace is around 15 to 30 years. As long as you have scheduled annual furnace maintenance, it should easily last over 15 years. Just like your car, your older furnace may need some basic repairs.
Why does a condensing furnace condensate water?
Because the exhaust gases are still very hot, all of that heat is wasted. As the gases cool, they condense to form water and carbon dioxide (which together form carbonic acid). The water (called condensate) drips out through a drain pipe, and the remaining flue gases are vented to the outdoors through a plastic pipe.
Is it normal for a furnace to have condensation?
It’s normal for high-efficiency furnaces to create condensation during its operation process (hence its name “condensing furnace”) so the leakage most likely requires a minor repair. The most common reasons that condensing furnaces start leaking include: Blocked condensate drains. Condensate pump problems.
Is it normal for a furnace to drain water?
Normally, high-efficiency furnaces drain away condensation via a draining system. But if that water ends up on your floor, that’s a sign that there may be an issue with your furnace.
Do high-efficiency furnaces need a drain?
A high-efficiency furnace (also called a condensing furnace) will always have condensation as a byproduct of heating your home. A floor drain is necessary for your high-efficiency furnace because the water has to go somewhere and a floor drain is the easiest and most effective outlet.
Where Should 90% furnaces drain to?
Most “90%” furnaces will have at least 2 internal drains, one for the heat exchanger and one for the vent. One will be located at the inducer outlet or on the inducer housing. The secondary heat exchanger outlet is sealed inside a plastic part called the collector box.
