Where should furnace condensate drain?

Where should furnace 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.

Does a high efficiency furnace 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.

How much condensate does a high efficiency furnace produce?

HomeTips.com says a high-efficiency furnace can produce as much as 5 or 6 gallons of water from condensation each day. Most of the time, condensate pipes are set up to carry condensation outdoors through a hole in an exterior wall. The water is able to drain harmlessly into the ground.

How do you know if your condensate pipe is frozen?

How do I know if the condensate pipe is frozen? If part of your condensate pipework is outside and does freeze during a prolonged period of very cold weather, you might hear a gurgling noise coming from the boiler and if your boiler has a digital display, you may see an ‘EA’ error code too.

How do I unclog my furnace condensate?

Many times the clogged drain can be cleared with wet/dry vacuum suction. You can also try removing the clog with a plumber’s snake. Use the access port to flush the drain with white vinegar, diluted hydrogen peroxide, or hot water and a drop of dish soap.

How much condensate does a furnace produce?

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.

Why do high-efficiency furnaces drain water?

High-efficiency furnaces create water because they have two heat exchangers, one more than a conventional furnace. The two heat exchangers absorb so much heat that the exhaust gas changes from a gas state to a liquid state. Condensation forms and then drains out through the condensate line.

Where does the condensate go in a high efficiency furnace?

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.

What happens if the drain line to the furnace freezes?

If the pipe that runs the condensate to the outside of the house freezes over, your furnace won’t be able to work! This is something that can unfortunately happen if the drip of condensate outside builds into an icicle that enters the drain line.

Do you need a condensate trap in a gas furnace?

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.

What to do about frozen condensate drain lines?

How to prevent frozen condensate drain lines? The best way to stop condensate drain line freeze is to use weather-proof sleeves placed around the drain. Shortening the drain pipe to give water less space in which to freeze can also be effective.
