Acidic condensate, that escapes up the flue, compared with ordinary boilers. Condensing boilers convert 86% or more of the fuel they use into useful heat. Older types of ordinary boilers convert as little as 60% of the fuel into useful heat. The change over to condensing boilers is set to save 0.8-0.9 million tonnes of carbon per year by the end of 2010. The one problem with these eco boilers is the acidic condensate they produce which has a pH of around 4. The acidic nature of this by-product means it needs to be neutralised before being discharged into the environment.
