The COWB3 Boiler: Efficient Performance for Years You can’t predict winter weather, so why risk your family’s warmth? Be ready 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 design. Plus, your heating is both quiet and draft-free. What makes the COWB3 even better is its easy integration with traditional radiator systems. When you purchase a COWB3 boiler through your Service Experts Heating & Air Conditioning in Plano, you’ll get reliability, durability and expert furnace installation service.
