Condensing boilers can be the most efficient type of boiler, often achieving a fuel-to-steam efficiency rate of up to 99 percent. These boilers recover part of the latent heat from unused water vapor that is wasted by other types of boilers by returning it to combine with the boiler water. As long as the temperature of the return water is less
