GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re looking for a high-efficiency boiler, look no further than the Lennox® GWB9-IH. This boiler has earned ENERGY STAR® certification, which means 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. 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. 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 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. These features don’t add up to a bulky machine. In fact, the GWB9-IH boiler is compact and easy to install in smaller spaces.
