GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re in the market for a high-efficiency boiler, the Lennox® GWB9-IH is the model for you. This boiler has earned ENERGY STAR® certification, which means it meets or exceeds federal guidelines for energy efficiency. But that’s not all. The GWB9-IH boiler also achieved an AFUE rating of 90%, which leads to 90% of the fuel used is converted to heat. High efficiency products are good for the environment, but how does it actually affect you you? Well, you could enjoy lower energy bills. Further, you’ll experience a home that heats up quicker 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 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, the GWB9-IH is compact and easy to install in smaller spaces.
