If you haven't yet heard of Viessmann, you'll be hearing more about them in the future. Long known in Europe for their quality and reliability, all Viessmann products are engineered for long life, reliable service, and outstanding quality. The Viessmann system advantage -- boiler/burner/controls/water heaters -- offers a complete system backed by the reputation of the world's largest boiler manufacturer.

Whether a boiler is required for a new heating system or as a replacement, the selection process must be a careful one. The choice should be made based on seasonal heating costs, comfort, convenience, and environmental emissions.

Typically, a boiler accumulates more hours of use than a car, and is expected to outlast it by at least five times. Therefore, quality construction, easy service, and system expandability are all as important as efficiency and reduced emissions.
