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, so it’s met the highest federal guidelines for energy efficiency. And that’s only the beginning. The GWB9-IH boiler also produces an AFUE rating of 90%, which translates to 90% of the fuel being converted to usable heat. Yes, being energy efficient helps the environment, but how does it actually affect you you? First off, you could start seeing a decrease in your utility bills. Further, you’ll experience a home that warms up quick thanks to the boiler’s cast-aluminum heat exchanger. This exchanger is stunning – it alone can transfer 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 won’t suffer from heating and cooling inconsistencies – it’ll always be just the temperature you want. The GWB9-IH boiler will heat your home with minimal operating sounds for years to come with its sealed combustion. It’ll stay durable for years, too, because it was created with heavy-gauge steel and includes 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.
