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 prepared for the worst – and cozy throughout the season – with a Lennox® COWB3 boiler. This standard-efficiency heating system uses 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 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 traditional radiator systems. When you select a COWB3 boiler through your Service Experts Heating & Air Conditioning in Columbus, you’ll get reliability, durability and expert furnace installation service.
