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 equipped for the worst – and cozy all 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. A domestic hot water coil takes your energy efficiency further by providing hot water at virtually no additional cost. 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 style. Not only is your heating quiet, it’s also draft-free. What makes this boiler even better is its easy integration with classic radiator systems.
