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, meaning it meets or exceeds federal guidelines for energy efficiency. But there’s more. 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 what’s in it for you? Well, 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. 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 provide warmth quietly for years 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 massive machine. In fact, the GWB9-IH is compact and easy to install in smaller spaces.
