The COWB3 Boiler: Efficient Performance for Years You can’t predict winter weather, so why risk your home’s warmth? Be ready 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 raised the bar for fuel-efficient heating. The COWB3 includes a domestic hot water coil that also increases energy efficiency. Winter temperatures are one thing, but it’s the wind that brings us over the edge. That’s maybe the biggest reason why we love the COWB3 system’s sealed-combustion construction. You’ll even get quiet and draft-free heating. What makes this boiler even better is its easy integration with conventional radiator systems. When you select a COWB3 boiler through your Strand Brothers Service Experts Heating & Air Conditioning in Austin, you’ll get reliability, durability and expert furnace installation service.
