The COWB3 Boiler: Efficient Performance for Years You can’t predict winter weather, so why risk your family’s comfort? Be equipped for the worst – and cozy all season – with a Lennox® COWB3 boiler. This standard-efficiency heating system includes a Beckett® oil burner, the product that set a benchmark for fuel-efficient heating. A domestic hot water coil takes your energy efficiency further by providing hot water at virtually no additional cost. 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 construction. Plus, your heating is both quiet and draft-free. What makes this product even better is its easy integration with classic radiator systems. When you select a COWB3 boiler through your R & M Climate Control Service Experts Heating & Air Conditioning in Knoxville, you’ll get reliability, durability and expert furnace installation service.
