High Efficiency Gas Furnace Water Drain

But a high efficiency furnace.

High efficiency gas furnace water drain.

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. Why a high efficiency furnace creates condensation how in the heck does a high efficiency furnace create condensation water anyway. The epa recommends that household water be between 6 5 and 8 5 for health reasons not because of damage to pipes. What is vented is a residual corrosive condensate of water and carbon dioxide.

Fix the problem with chemical tablets and a larger drain hose. A lower efficiency furnace extracts some heat from combustion gases and then quickly vents them out the flue pipe. 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.

Add new tablets monthly during air. Condensate from a high efficiency furnace typically has a ph of about 5 0 but can range from 3 5 to 6 5. If you notice water around the furnace the condensate drain may be clogged with slime. The resulting no2 nitrogen dioxide and no nitrous oxide dissolve into the water vapor in the exhaust stream to form nitric acid.

It moves the air with a circulating fan. It uses a venting system to extract that heat before venting. The condensate trap is absolutely mandatory for a high efficiency gas furnace. 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. This is typically flown out of a pvc pipe that comes from the furnace and drains into the floor drain in your furnace room. This is one of the things that make it different from a standard efficiency furnace. A high efficiency condensing furnace can achieve efficiency ratings of 90 or above.

Additionally the inducer motor would suck air through the drain if it weren t trapped which could. How a high efficiency condensing furnace differs. Shove the tablets into the drain pan opening and push them in farther using a dowel or long screwdriver. In old fashioned low efficiency gas burners all that gas the co2 the water vapor and the nitrogen products known collectively as nox went up the hot chimney into the atmosphere.
