The COWB3 Boiler: Efficient Performance for Years You never know just how harsh the winter will be, so why risk your family’s comfort? Be prepared 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. Thanks to a domestic hot water coil that provides hot water at almost no extra cost, you’ll see greater 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 construction. Plus, your heating is both quiet and draft-free. What makes this boiler even better is its easy integration with classic radiator systems.
