The COWB3 Boiler: Efficient Performance for Years You never know just how harsh the winter will be, so why risk your family’s warmth? Be prepared for the worst – and cozy all winter – with a Lennox® COWB3 boiler. This standard-efficiency heating system includes a Beckett® oil burner, the product that raised the bar for fuel-efficient heating. The COWB3 includes a domestic hot water coil that also increases energy efficiency. Winter temperatures are one thing, but it’s the wind that really chills our bones. That’s why we love the COWB3 system’s sealed-combustion style. Not only is your heating quiet, it’s also draft-free. What makes the COWB3 even better is its simple integration with conventional radiator systems. When you buy a COWB3 boiler through your Roland J.
