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 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 brings us over the edge. That’s on reason why we love the COWB3 system’s sealed-combustion construction. Plus, your heating is both quiet and draft-free. What makes this boiler even better is its easy integration with conventional radiator systems.
