The COWB3 Boiler: Efficient Performance for Years You can’t predict winter weather, so why risk your family’s warmth? 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 brings us over the edge. That’s why we love the COWB3 system’s sealed-combustion construction. Not only is your heating quiet, it’s also draft-free. What makes the COWB3 even better is its effortless integration with conventional radiator systems.
