The COWB3 Boiler: Efficient Performance for Years Winter weather can take a turn for the worse without warning, so why risk your home’s warmth? 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. 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 really chills our bones. That’s on reason why we love the COWB3 system’s sealed-combustion design. Plus, your heating is both quiet and draft-free. What makes the COWB3 even better is its simple integration with classic radiator systems. When you buy a COWB3 boiler through your Rob's Albertan Service Experts Heating & Air Conditioning in Edmonton, you’ll get reliability, durability and expert furnace installation service.
