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, meaning it meets or exceeds federal guidelines for energy efficiency. And that’s only the beginning. The GWB9-IH boiler also produces an AFUE rating of 90%, which translates to 90% of the fuel being converted to usable heat. Yes, being energy efficient helps the environment, but what does it really mean for you? For starters, you could enjoy lower energy bills. Further, you’ll experience a home that heats up quicker 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 won’t suffer from heating and cooling inconsistencies – it’ll always be just the temperature you want. The GWB9-IH boiler will provide warmth quietly for years 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. These features don’t add up to a bulky machine. In fact, the GWB9-IH is compact and easy to install in smaller spaces.
