The Vitocrossal 300 Gas Fired Hot Water Boiler has a reliable heat exchanger that is capable of producing a high efficiency heat transfer and a high condensation rate throughout the heat exchanger surfaces that allow the flue gases the flow through the system. The boiler’s water and gases also flow through in a counter flow method. This creates a low to zero heat loss. These boilers can run with 98.3% efficiency through the most intense condensation from the boiler. The flue gas temperatures are about 9-27 degrees Fahrenheit above the return temperature. Also contributing to the boilers’ efficiency is that the combustion has low NOx emissions, which creates a cleaner combustion.
