GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re looking for a high-efficiency boiler, the Lennox® GWB9-IH is the model for you. This boiler has earned ENERGY STAR® certification, so it’s met the highest 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 how does it actually affect you you? Well, you could start seeing a decrease in your utility bills. Another nice benefit is that you may 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 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. It may seem like a lot, but all this doesn’t add up to a bulky machine. In fact, this boiler is compact and easy to install in smaller spaces.
