GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re searching for a high-efficiency boiler, consider the Lennox® GWB9-IH boiler. This boiler has received ENERGY STAR® certification, which means 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 leads to 90% of the fuel used is converted to heat. High efficiency products are good for the environment, but what does it really mean for you? First off, you could start seeing a decrease in your 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 quietly warm your home for years to come 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. The benefits are plentiful, but they don’t add up to a bulky machine. In fact, the GWB9-IH is compact and easy to install in smaller spaces. While we’re talking about installation, let our staff at D.A.
