GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re looking 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. But that’s not all. The GWB9-IH boiler also produces an AFUE rating of 90%, which leads to 90% of the fuel used is converted to heat. Yes, being energy efficient helps the environment, but what does it really mean for you? For starters, you could start seeing a decrease in your utility bills. Further, you’ll experience a home that heats up quicker thanks to the boiler’s cast-aluminum heat exchanger. This exchanger alone transfers 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 quietly warm your home for years to come 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. It may seem like a lot, but all this doesn’t add up to a large machine. In fact, the GWB9-IH boiler is compact and easy to install in smaller spaces.
