The COWB3 Boiler: Efficient Performance for Years Winter weather can take a turn for the worse without warning, 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 uses a Beckett® oil burner, the product that set the standard 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 maybe the biggest reason why we love the COWB3 system’s sealed-combustion design. Plus, your heating is both quiet and draft-free. What makes this boiler even better is its effortless integration with classic radiator systems.
