The COWB3 Boiler: Efficient Performance for Years Winter weather can take a turn for the worse without warning, so why risk your family’s comfort? Be equipped for the worst – and cozy throughout the season – with a Lennox® COWB3 boiler. This standard-efficiency heating system features 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 why we love the COWB3 system’s sealed-combustion design. You’ll even get quiet and draft-free heating. What makes the COWB3 even better is its simple integration with conventional radiator systems. When you purchase a COWB3 boiler through your Winnipeg Supply Service Experts Heating & Air Conditioning in Winnipeg, you’ll get reliability, durability and expert furnace installation service.
