The COWB3 Boiler: Efficient Performance for Years You can’t predict winter weather, so why risk your family’s warmth? 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 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 takes winter cold to the next level. That’s why we love the COWB3 system’s sealed-combustion design. You’ll even get quiet and draft-free heating. What makes this product even better is its easy integration with traditional radiator systems. When you select a COWB3 boiler through your Service Experts Heating & Air Conditioning in Dublin, you’ll get reliability, durability and expert furnace installation service.
