GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re in the market for a high-efficiency boiler, consider the Lennox® GWB9-IH boiler. This boiler has earned ENERGY STAR® certification, meaning it meets or exceeds federal guidelines for energy efficiency. But there’s more. 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’s in it for you? First off, you could enjoy lower energy bills. But, you’ll also 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 be too hot or too cold. It’ll be just right. The GWB9-IH boiler will heat your home with minimal operating sounds 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. These features don’t add up to a large machine. In fact, this boiler is compact and easy to install in smaller spaces. Speaking of installation, let our experts at Barlow Service Experts Heating & Air Conditioning in Ogden take care of that for you.
