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.

Condensate water from high efficiency furnace.

How a high efficiency condensing furnace differs. Condensate drains on the high efficiency condensing units were freezing where the drain pipes terminated outside the house. If the water sits in a trap and evaporates the acidity and corrosive effect will increase. With the pipes blocked the condensate backed up into the furnaces where safety switches shut the units down.

Like a conventional furnace it takes in cold air from the house and runs it through an air filter. You can capture that heat with a high efficiency condensing furnace. 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.

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. How to purchase and install a condensate neutralizer. It moves the air with a circulating fan. Problems with the condensate pump.

You can prevent slime and eliminate drain tube clogs in two easy steps. Condensate from a high efficiency furnace typically has a ph of about 5 0 but can range from 3 5 to 6 5. Condensing appliances extract additional btus from the water vapor in the flue gas. Most new residential and commercial heating and hot water systems include a furnace boiler or domestic water heater of the high efficiency condensing type.

Condensation from air conditioning coils contains bacteria that can form slime and clog the condensate pan drain tube. What is vented is a residual corrosive condensate of water and carbon dioxide. When you see water puddling around the furnace with the a c running you have a clogged condensate drain tube. While the condensing furnace is different in its design and repair needs it does have some similarities to a conventional furnace.

A high efficiency condensing furnace can achieve efficiency ratings of 90 or above. It uses a venting system to extract that heat before venting. 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. 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.
