High Efficiency Gas Furnace Water Drain

A high efficiency condensing furnace can achieve efficiency ratings of 90 or above.

High efficiency gas furnace water drain.

It moves the air with a circulating fan. How a high efficiency condensing furnace differs. The resulting no2 nitrogen dioxide and no nitrous oxide dissolve into the water vapor in the exhaust stream to form nitric acid. It uses a venting system to extract that heat before venting.

Fix the problem with chemical tablets and a larger drain hose. The epa recommends that household water be between 6 5 and 8 5 for health reasons not because of damage to pipes. A lower efficiency furnace extracts some heat from combustion gases and then quickly vents them out the flue pipe. Shove the tablets into the drain pan opening and push them in farther using a dowel or long screwdriver.

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 the drain if it weren t trapped which could. If you notice water around the furnace the condensate drain may be clogged with slime. But if there is an issue or a clog anywhere in the condensate line or drain water will begin overflowing and leaking from the furnace and onto the floor.

What is vented is a residual corrosive condensate of water and carbon dioxide. Why a high efficiency furnace creates condensation how in the heck does a high efficiency furnace create condensation water anyway. And it has a gas burner with electronic ignition although condensing. High efficiency boilers and furnaces require a condensate neutraliser to protect drain pipes from corrosion.

The condensate trap is absolutely mandatory for a high efficiency gas furnace. Condensate from a high efficiency furnace typically has a ph of about 5 0 but can range from 3 5 to 6 5. Your high efficiency furnace has an entire system set up to drain away the condensation it produces. But a high efficiency furnace.

While the condensing furnace is different in its design and repair needs it does have some similarities to a conventional furnace like a conventional furnace it takes in cold air from the house and runs it through an air filter. It s all about how the furnace extracts heat from combustion gases. This is one of the things that make it different from a standard efficiency furnace. Add new tablets monthly during air.
