The COWB3 Boiler: Efficient Performance for Years You can’t predict winter weather, so why risk your family’s comfort? 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 style. Plus, your heating is both quiet and draft-free. What makes the COWB3 even better is its effortless integration with conventional radiator systems. When you purchase a COWB3 boiler through your TML Service Experts Heating & Air Conditioning in Boise, you’ll get reliability, durability and expert furnace installation service.
