GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re in the market 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. But there’s more. The GWB9-IH boiler also achieved an AFUE rating of 90%, which means 90% of the fuel is converted to usable heat. We know energy efficiency is great for the environment, but what does it really mean for you? For starters, 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 be too hot or too cold. It’ll be just right. The GWB9-IH boiler will provide warmth quietly for years to come 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. It may seem like a lot, but all this doesn’t add up to a bulky machine. In fact, the GWB9-IH boiler is compact and easy to install in smaller spaces.
