The COWB3 Boiler: Efficient Performance for Years You never know just how harsh the winter will be, so why risk your family’s warmth? Be prepared for the worst – and cozy all season – with a Lennox® COWB3 boiler. This standard-efficiency heating system uses a Beckett® oil burner, the product that set a benchmark 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 takes winter cold to the next level. That’s on reason why we love the COWB3 system’s sealed-combustion design. Not only is your heating quiet, it’s also draft-free. What makes the COWB3 even better is its simple integration with classic radiator systems. When you select a COWB3 boiler through your Broad Ripple Service Experts Heating & Air Conditioning in Indianapolis, you’ll get reliability, durability and expert furnace installation service.
