GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re searching 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 there’s more. The GWB9-IH boiler also produces 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 how does it actually affect you you? Well, you could see lower utility bills. Another nice benefit is that you may experience a home that warms up quick 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 won’t be too hot or too cold. It’ll be just right. 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. The benefits are plentiful, but they don’t add up to a large machine. In fact, this boiler is compact and easy to install in smaller spaces.
