Condensate Water From High Efficiency Furnace

When the flue gas drops below its dew point of approximately 135 degrees fahrenheit it starts to condense.

Condensate water from high efficiency furnace.

It s important to note that ph is a logarithmic scale so ph 5 water is 10 times more acidic than ph6. Like a conventional furnace it takes in cold air from the house and runs it through an air filter. This residual liquid is highly acidic. It moves the air with a circulating fan.

When you see water puddling around the furnace with the a c running you have a clogged condensate drain tube. Most new residential and commercial heating and hot water systems include a furnace boiler or domestic water heater of the high efficiency condensing type. In older homes a whole house trap might be buried in the floor and the main sewer line to the street is most likely cast iron even if modern pvc drains have been installed in the house. All high efficiency furnaces create acidic water as a by product of the combustion process so it s best to install a condensate neutralizer before corrosion causes damage to your pipes septic system or sewer system.

Condensing appliances extract additional btus from the water vapor in the flue gas. A clog or problem in the condensate system your high efficiency furnace has an entire system set up to drain away the condensation it produces. And it has a gas burner with electronic ignition although condensing furnaces may have more electronic controls. You can capture that heat with a high efficiency condensing furnace.

Condensate from a high efficiency furnace typically has a ph of about 5 0 but can range from 3 5 to 6 5. You can prevent slime and eliminate drain tube clogs in two easy steps. 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. How to purchase and install a condensate neutralizer.

What is vented is a residual corrosive condensate of water and carbon dioxide. Condensate drainage in a high efficiency gas furnace high efficiency or 90 or condensing furnaces use a set of two heat exchangers in order to retrieve more heat from the combustion products than their mid efficiency counterparts. While the condensing furnace is different in its design and repair needs it does have some similarities to a conventional furnace. How a high efficiency condensing furnace differs.

It uses a venting system to extract that heat before venting. A high efficiency condensing furnace can achieve efficiency ratings of 90 or above. Condensate drains on the high efficiency condensing units were freezing where the drain pipes terminated outside the house. Problems with the condensate pump.
