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 throughout the season – with a Lennox® COWB3 boiler. This standard-efficiency heating system includes a Beckett® oil burner, the product that set the standard 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 takes winter cold to the next level. That’s maybe the biggest reason why we love the COWB3 system’s sealed-combustion construction. You’ll even get quiet and draft-free heating. What makes this product even better is its effortless integration with classic radiator systems. When you select a COWB3 boiler through your Peitz Service Experts Heating & Air Conditioning in Pierre, you’ll get reliability, durability and expert furnace installation service.
