The Efficiency You Want And The Reliability You Need
High efficiency boilers were introduced in response to the energy crisis of the seventies. Most first generation high efficiency boilers were simply standard units that had been hurriedly modified to boost efficiency. These boilers obtained higher efficiencies by permitting steady-state condensation in the combustion chamber. Failure to adequately protect the combustion chamber and heat exchanger from the corrosive effects of condensate meant that most first generation units failed prematurely.

The units condensed, eventually corroded, and finally were discarded. Manufacturers learned from their mistakes. They upgraded materials, redesigned heat exchangers and refined their manufacturing techniques. The second generation of high efficiency boilers, which began to appear in the late eighties, was a vast improvement. However, second generation units still experience damage from condensation. Although the materials used in second generation high efficiency boilers last considerably longer, they will eventually succumb to corrosion.

Third Generation Technology

Primary Heat Exchanger After two decades of trial-and-error, the boiler industry has finally realized that high efficiency and long product life can only be obtained by preventing condensation from occurring in the combustion chamber. Raypak's Advanced Design Boiler is the first of a new generation of boilers that can obtain ultra-high efficiency without compromising product life. The "secret" to the ADB's longevity is that condensation occurs only in a corrosion-resistant secondary heat exchanger. The ADB is designed so that condensation will not occur in the primary heat exchanger or the combustion chamber. The result is an ultra-high efficiency product that lasts.
Welcome to the Future of Boiler Technology.
