GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re looking for a high-efficiency boiler, consider the Lennox® GWB9-IH boiler. This boiler has earned ENERGY STAR® certification, so it’s met the highest 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. Yes, being energy efficient helps the environment, but what does it really mean for you? First off, you could enjoy lower energy bills. Further, you’ll experience a home that warms up quick thanks to the boiler’s cast-aluminum heat exchanger. Even alone, this exchanger 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 will always be the perfect temperature. The GWB9-IH boiler will heat your home with minimal operating sounds 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. It may seem like a lot, but all this doesn’t add up to a massive machine. In fact, this boiler is compact and easy to install in smaller spaces.
