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 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. High efficiency products are good for the environment, but how does it actually affect you you? For starters, you could enjoy lower energy 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 will always be the perfect temperature. The GWB9-IH boiler will quietly warm your home year after year 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. The benefits are plentiful, but they don’t add up to a bulky machine. In fact, the GWB9-IH boiler is compact and easy to install in smaller spaces.
