Generally speaking, natural gas steam boilers should have a minimum AFUE rating of 80 percent, meaning 80 percent of the energy consumed is converted to steam. (For context, hot water boilers generally have higher AFUE ratings than steam boilers, and condensing boilers typically have high-efficiency ratings, as well.

Condensate from condensing boilers is acidic and corrosive to many materials and should be treated to maintain a pH of no less than 5 before disposal. There can be a wide variation of the pH of condensate from condensing appliances due to the chemical make-up of the gas being combusted or from the way in which the appliance is operating in a particular application.

2019/5/24 · Condensate units increase efficiency and can even reduce your utility costs. Since the steam that is returned to the boiler is already similar in temperature to the boiler water, less energy is necessary to reheat it – thus reducing your oil, gas, or electricity costs. In addition, capturing steam that would have otherwise been released

As with furnaces, condensing gas-fired boilers are relatively common, and significantly more efficient than non-condensing boilers (unless very sophisticated controls are employed). Oil-fired condensing boilers are uncommon in the U.S. for several reasons related to lower latent heat potential, and potential for greater fouling with conventional fuel oil.

Reducing boiler fuel needs through condensate recovery leads to less air pollution by lowering CO 2, NO x and SO x emissions. Additionally, condensate recovery lines can also limit vapor clouds to reduce noise generated from atmospheric condensate discharge and help prevent build-up of water on the ground, considerably improving a plant's work environment.
