The COWB3 Boiler: Efficient Performance for Years You never know just how harsh the winter will be, so why risk your home’s warmth? Be equipped for the worst – and cozy all season – with a Lennox® COWB3 boiler. This standard-efficiency heating system uses 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 why we love the COWB3 system’s sealed-combustion construction. Plus, your heating is both quiet and draft-free. What makes the COWB3 even better is its effortless integration with classic radiator systems. When you buy a COWB3 boiler through your Knochelmann Service Experts Heating & Air Conditioning in Sharonville, you’ll get reliability, durability and expert furnace installation service.
