The COWB3 Boiler: Efficient Performance for Years You can’t predict winter weather, so why risk your family’s comfort? Be prepared 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 raised the bar 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 style. Not only is your heating quiet, it’s also draft-free. What makes the COWB3 even better is its effortless integration with traditional radiator systems. When you purchase a COWB3 boiler through your Calverley Service Experts Heating and Air Conditioning in Fort Worth, you’ll get reliability, durability and expert furnace installation service.
