The COWB3 Boiler: Efficient Performance for Years You can’t predict winter weather, so why risk your family’s comfort? Be ready for the worst – and cozy throughout the season – with a Lennox® COWB3 boiler. This standard-efficiency heating system features a Beckett® oil burner, the product that set a benchmark 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 on reason why we love the COWB3 system’s sealed-combustion design. You’ll even get quiet and draft-free heating. What makes this boiler even better is its simple integration with conventional radiator systems.
