The COWB3 Boiler: Efficient Performance for Years You never know just how harsh the winter will be, 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 uses a Beckett® oil burner, the product that set the standard 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 why we love the COWB3 system’s sealed-combustion construction. Plus, your heating is both quiet and draft-free. What makes the COWB3 even better is its easy integration with classic radiator systems. When you buy a COWB3 boiler through your Service Experts Heating & Air Conditioning in Memphis, you’ll get reliability, durability and expert furnace installation service.
