GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re searching for a high-efficiency boiler, look no further than the Lennox® GWB9-IH. This boiler has achieved ENERGY STAR® certification, meaning it meets or exceeds federal guidelines for energy efficiency. But that’s not all. 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 how does it actually affect you you? First off, you could see lower utility bills. Further, you’ll experience a home that warms up quick 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 will always be the perfect temperature. 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. The benefits are plentiful, but they don’t add up to a large machine. In fact, this boiler is compact and easy to install in smaller spaces.
