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 received ENERGY STAR® certification, so it’s met the highest federal guidelines for energy efficiency. But that’s not all. The GWB9-IH boiler also reached an AFUE rating of 90%, which leads to 90% of the fuel used is converted to heat. We know energy efficiency is great for the environment, but what’s in it for you? Well, you could start seeing a decrease in your utility bills. But, you’ll also experience a home that heats up quicker 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 will always be the perfect temperature. 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, 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 large machine. In fact, the GWB9-IH boiler is compact and easy to install in smaller spaces.
