High Efficiency Furnace Condensate Neutralizer

123rf com condensate from a high efficiency furnace typically has a ph of about 5 0 but can range from 3 5 to 6 5.

High efficiency furnace condensate neutralizer. Because of this they generate flue gases much colder than those of a mid efficiency or natural draft unit. 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. 150 000btu hr 8hr 48l 10 5ig day. One brand of condensate neutralizers is neutrasafe.

It s important to note that ph is a logarithmic scale so ph 5 water is 10 times more acidic than ph6. The amount of condensate produced by a high efficiency furnace is approximately 4l 1gal per 100 000 btu per hour. Condensate produced by high efficiency condensing equipment including residential and commercial gas boilers hot water heaters and furnaces has inherently low ph is acidic and poses a problem for sewer piping and septic systems. You may need a system to neutralize the liquid condensate before you send the liquid to your drainage system.

High efficiency boilers and furnaces require a condensate neutraliser to protect drain pipes from corrosion. There is no simple answer. As an example a 150 000 btu furnace or boiler running approximately 8 hours a day in the winter months would produce roughly 50l or 11ig of condensate. Due to the high acidic levels in the condensate produced by high efficiency furnaces boilers or water heaters it is recommended that the condensate be neutralized to prevent damage to drains.

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. For more information on this issue see furnace condensate proves tricky to manage. Most new residential and commercial heating and hot water systems include a furnace boiler or domestic water heater of the high efficiency condensing type. Our neutralizer designs are the direct result of boiler and furnace manufacturers needs for a high quality universal re chargeable and simple condensate neutralizer.
