Neutralizing Condensate in Condensing Boilers and Hot Water Heaters
With the growth of high efficiency condensing boilers, furnaces and hot water heaters, the installation of a condensate neutralizer is now a mandatory requirement. What is Condensate? High efficiency condensing boilers and hot water heaters extract additional BTUs form the water vapor in the flue gas. When the gas drops below 130°F, it starts to condense and produces an acidic liquid which has the potential to cause damage to your piping, drains and other system components. When your boiler or hot water heater is operating in full condensing mode, approximately one gallon of condensate gets created for every 100,000 BTUs of input. So if your system runs for 1,200 hours each year, it will produce 1,200 gallons of condensate! The acidic level of the condensate is measured in pH on a scale from 0 to 14. Most condensate will have a pH between 2.9 and 4 with 7 being neutral. This scale is not linear; each step below 7 is 10 times more acidic than the next higher number. Treated c...
