GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re looking for a high-efficiency boiler, the Lennox® GWB9-IH is the model for you. This boiler has earned ENERGY STAR® certification, meaning it meets or exceeds federal guidelines for energy efficiency. And that’s only the beginning. The GWB9-IH boiler also produces an AFUE rating of 90%, which means 90% of the fuel is converted to usable heat. Yes, being energy efficient helps the environment, but what does it really mean for you? First off, you could see lower utility bills. Another nice benefit is that you may experience a home that heats up fast thanks to the boiler’s cast-aluminum heat exchanger. This exchanger alone transfers heat three times faster than those made with cast iron. An electronic ignition control will monitor water temperature and turn the boiler on only when necessary, so your home will always be the perfect temperature. The GWB9-IH boiler will quietly warm your home year after year with its sealed combustion. It’ll stay durable for years, too, since it was made with heavy-gauge steel and has a baked-on paint finish. These features don’t add up to a bulky machine. In fact, this boiler is compact and easy to install in smaller spaces.
