Does a furnace produce condensation?
High efficiency gas furnaces produce condensation as a normal part of their operation. What's not normal is for water to be leaking out of the furnace. All furnaces have a drain pipe taking excess water to a floor drain or outside.
Why is my furnace Condensating so much?
If you have a high-efficiency furnace, it's likely that your furnace system will generate condensation. A condensation leak can be the cause of two things: damage/clogged tubing or a floor drain clog. If the tubing that aids the draining is damaged or clogged, this is where a leak occurs.
Which furnace type produces the most condensation?
High-efficiency furnacesHigh-efficiency furnaces extract as much heat from their exhaust products as possible, so the exhaust products in high-efficiency furnaces produce lots of condensation. HomeTips.com says a high-efficiency furnace can produce as much as 5 or 6 gallons of water from condensation each day.
How do I stop condensation in my furnace?
Keep in mind that lower temperatures hold lower moisture. So one solution would be to turn the heat up so it can hold more moisture, or turn the humidifier down till the condensation goes away.
Can a furnace leak a lot of water?
Leaks are a fairly common issue for furnaces. There are a number of reasons they happen; some major, others minor. If you come home to a furnace leaking water, you'll most likely need a technician to come out and diagnose the problem. But it never hurts to stay educated on the different components of your home.
Why is my furnace dripping water?
Causes of Furnace Leaks This can be the result of clogged condensation tubing, breaks in the condensation line or other possible issues with the pump. Humidifier issues are also a possible cause of furnace leaks. A clogged filter or drain in the humidifier can easily cause any furnace to produce unwanted moisture.
Do high efficiency furnaces create condensation?
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.
Does running furnace increase humidity?
Right? So when an atmospheric combustion furnace inside your house is running, it causes dry outdoor air to come in, and that lowers your humidity. So in the case of atmospheric combustion furnaces inside the conditioned space, we can say that one of the results of operating it is drier air.
Do high efficiency furnaces dehumidify?
The short answer is yes, you do need a humidifier with a high-efficiency furnace. These furnaces may contribute to low humidity levels in the home, but winter humidity levels are already so low that you may need a humidifier with any furnace, not just a new high-efficiency one.
Will turning up the heat reduce condensation?
Heating. As air warms up, it can hold more moisture - so using heaters in wet areas can reduce condensation.
Does a dehumidifier get rid of condensation?
Dehumidifiers seem to be the obvious way of reducing humidity, removing condensation, stopping walls becoming damp and preventing mould. But a more effective solution is to give your home a small but consistent background movement of fresh air. This will help keep your home feeling fresher, healthier and mould free.
Can a dirty furnace filter cause condensation?
If your air filter gets too congested during the summer cooling season, it may cause lack of airflow to the evaporator or cooling coils. This lack of adequate airflow causes condensation that is normally produced during the cooling process to freeze.

Where do I drain my high efficiency furnace condensate?
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.
What is condensation on a furnace?
Furnace condensation is typically a buildup of water around the unit's base. This can be caused by a few different phenomena but doesn't necessarily indicate a problem with the furnace. Advertisement.
Why is my furnace leaking condensation?
If the furnace is producing condensation during the winter, the problem could be that one of these pipes has frozen and is backing up all the way to the main furnace unit. The condensation is then draining onto or around the area of your house where the furnace is.
What happens if a furnace hose is blocked?
If these hoses become blocked up, knotted or obstructed in any way, it could cause the natural flow of water to back up onto the furnace and produce the appearance of condensation.
What is a frozen pipe in a furnace?
Frozen Pipes. A series of pipes used for various purposes is connected to your furnace. These pipes run throughout your house, and certain pipes even run outside. If the furnace is producing condensation during the winter, the problem could be that one of these pipes has frozen and is backing up all the way to the main furnace unit.
Can a furnace produce condensation?
Certain types of furnaces naturally produce condensation over time. This is not an issue. These furnaces often have a specialized drain used to collect the condensation that should prevent you from ever seeing it. If you notice your furnace is producing more condensation than normal, check to make sure nothing is obstructing the condensation drain and preventing it from emptying.
How many drains does a furnace have?
Most furnaces will have at least two internal drains, typically one for the heat exchanger and one for the vent, usually at the inducer outlet or on the inducer housing. The secondary heat exchanger outlet is sealed inside a plastic part called the collector box, designed to collect the condensate and drain it.
How does a high efficiency furnace work?
High efficiency (or 90%, or condensing) furnaces use a set of two heat exchangers to retrieve more heat from the combustion products than their mid-efficiency counterparts. Because of this, they generate flue gases much colder than those of a mid-efficiency or natural draft unit. That not only completely changes the way the furnace has to be vented (I will talk about venting specifically in a later tip), but a lot of condensate is also generated, which we'll focus on. This water comes from two sources: moisture, which was already present in the combustion air, and the combustion process itself, as the hydrogen atoms from the natural gas molecules (methane, CH4) combine with oxygen to form water. Now, as technicians, you don’t need to know this part, but if you’re a bit into chemistry, here’s the basic chemical equation:
What is CH4 + 2 O2 + heat?
CH4 + 2 O2 + heat = CO 2 + 2 H2O. That equation means that in perfect combustion, for every molecule of CO2 you produce, two water molecules are also produced. That adds up to a lot of water vapor. For the furnace to work properly, that condensation needs to be drained out.
What are the three things that are needed to maintain combustion?
To maintain combustion (burning), you need three things: fuel, heat, and oxygen. If you have all three in the proper proportion, you can maintain a continuous state of combustion. Remove one (or reduce one sufficiently), and the triangle of combustion can collapse. In a common NG gas furnace, the heat…. 11/13/2019.
Can you run a furnace drain in an area that freezes?
Avoid running the drain in an area where it could freeze. That includes running it under the natural fresh air inlet if there is one. Finally, note that furnace condensate is acidic, and some states/provinces/countries may require the condensate to be neutralized prior to draining. —Ben. Share this:
Do condensate drains go into traps?
All condensate drains go into a trap. The condensate trap is absolutely mandatory for a high-efficiency gas furnace. Since the drain taps into the exhaust system, leaving it open to the air would allow for a potential exhaust/flue gas leak in the living space, which is a big no-no. Additionally, the inducer motor would suck air through ...
Why does a new furnace cause condensation?
New furnaces hooked up to existing flues can result in condensation problems because they are more efficient than old models. While much of the heat produced by older heaters was lost out the flue, this heat prevented condensation by keeping the chimney or vent pipe warm so that air moved upward.
What happens when gas goes up the chimney?
When everything is working properly, the vapor is pushed up out of the the end of the pipe and into the atmosphere before it condenses. If something is awry, the vapor cools before it exits the flue and condenses right then and there. In order to stop the vapor from condensing, conditions must be adjusted so that it does not cool before leaving the chimney.
Is carbon monoxide in a furnace dangerous?
This exhaust from the furnace contains dangerous carbon monoxide. Have a technician check the flue for leaks and test your home's carbon monoxide levels if you notice moisture in the furnace vent. Carbon monoxide is o dorless and colorless, and it can be deadly. References.
Is it dangerous to have condensation in your flue?
It can lead to a dangerous situation in your home that might not be obvious until it is too late. Determining the cause of the condensation in the flue can help you determine what repairs are necessary.
Is a furnace vent dangerous?
Condensation in the flue or vent pipe is not dangerous in itself, but can create a dangerous condition. Over time, the moisture, as well as the chemicals released by the furnace, can damage the flue and vent pipe. Rust and corrosion create leaks that allow the vapor to make its way into your home. This exhaust from the furnace contains dangerous carbon monoxide. Have a technician check the flue for leaks and test your home's carbon monoxide levels if you notice moisture in the furnace vent. Carbon monoxide is odorless and colorless, and it can be deadly.
Condensation From High-Efficiency VS Standard-Efficiency Gas Furnace
Furnace leaking water in winter is much more common with high-efficiency gas furnaces. That’s because standard-efficiency furnaces are not supposed to leak water at all. Running a standard-efficiency furnace doesn’t involve condensation; running a high-efficiency furnace does. We’ll explain this later on.
Do You Need Professional Help With Furnace Leaking Water?
In most cases, you will need a professional to take a look at your furnace. Disassembling and reassembling the furnace is a complex process and usually, the primary reason why you would need a professional.
How to tell if a furnace is condensing or condensing?
It is relatively easy to identify your furnace type, and to narrow down the reason for the leak. Look at the exhaust pipe. When the pipe is white plastic furnace PVC pipe, then it is a condensing furnace, making it high efficiency. A metal exhaust pipe has a standard efficiency rating and does not produce condensation.
What happens when a furnace releases exhaust gases?
When a high efficiency furnace releases the exhaust gases, condensation is created. This condensation is a significant amount of moisture on the PVC pipe, and it needs to be drained either into a floor drain or a condensation pump. A water leakage occurs when the condensation is unable to drain properly.
How Does My Gas Furnace Work And Does it Produce Water?

Why is my furnace not working?
Water leaking inside the furnace can also cause damage to the internal electrical components. This can cause your furnace not to work all together. The circuit board, for example, is responsible for transmitting the signals needed to start the furnace's heating procedure. If water leaks on to the circuit control board, it won't be long before you need to replace it!
What happens after a furnace heat exchanger?
After the burning gas exits the primary heat exchanger, it proceeds to the secondary heat exchanger. The secondary heat exchanger is where the exhaust or flue gas undergoes further heat exchange. This creates water vapor forms. ( Find out more about Heat Exchangers here! ). As water transitions from a vapor to a liquid, more heat is released into the secondary heat exchanger. In this way, the furnace functions even more efficiently. From there, the condensation is drained into a condensate pump or a floor drain.
