GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re searching for a high-efficiency boiler, consider the Lennox® GWB9-IH boiler. This boiler has received ENERGY STAR® certification, meaning it meets or exceeds federal guidelines for energy efficiency. And that’s only the beginning. The GWB9-IH boiler also reached an AFUE rating of 90%, which means 90% of the fuel is converted to usable heat. High efficiency products are good for the environment, but what does it really mean for you? Well, 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 won’t be too hot or too cold. It’ll be just right. The GWB9-IH boiler will provide warmth quietly year after year with its sealed combustion. It’ll stay durable for years, too, having been created with heavy-gauge steel and receiving a baked-on paint finish. These features don’t add up to a large machine. In fact, the GWB9-IH is compact and easy to install in smaller spaces.
