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 there’s more. The GWB9-IH boiler also reached an AFUE rating of 90%, which means 90% of the fuel is converted to usable heat. Yes, being energy efficient helps the environment, but what’s in it for you? First off, you could see lower utility bills. But, you’ll also experience a home that heats up fast 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 heat your home with minimal operating sounds year after year with its sealed combustion. It’ll stay durable for years, too, because it was created with heavy-gauge steel and includes 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 is compact and easy to install in smaller spaces.
