GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re in the market for a high-efficiency boiler, look no further than the Lennox® GWB9-IH. This boiler has received ENERGY STAR® certification, meaning 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 leads to 90% of the fuel used is converted to heat. High efficiency products are good for the environment, but what does it really mean for you? Well, you could start seeing a decrease in your utility bills. Another nice benefit is that you may experience a home that heats up fast thanks to the boiler’s cast-aluminum heat exchanger. This exchanger is stunning – it alone 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 will always be the perfect temperature. The GWB9-IH boiler will quietly warm your home for years 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 bulky machine. In fact, this boiler is compact and easy to install in smaller spaces. As long as we’re on the topic of installation, let our staff at Service Experts Heating & Air Conditioning in Cocoa take care of that for you.
