Watertube Boilers

A condensing boiler is a hot water heating system designed to recover energy normally discharged through the chimney as waste. How it works is the water vapor produced by the burning of gas in the boiler condenses back into liquid water releasing the latent heat of vaporization from the water. Because latent heat is a more significant source of energy, condensing boilers have efficiency ratings up to 98%.
