GWB9-IH Boilers: High-Efficiency with Faster Heat Transfer If you’re in the market for a high-efficiency boiler, the Lennox® GWB9-IH is the model for you. This boiler has received ENERGY STAR® certification, so it’s met the highest federal guidelines for energy efficiency. And that’s only the beginning. The GWB9-IH boiler also reached an AFUE rating of 90%, which leads to 90% of the fuel used is converted to heat. Yes, being energy efficient helps the environment, but how does it actually affect you you? Well, you could see lower 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. 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 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, since it was made with heavy-gauge steel and has a baked-on paint finish. These features don’t add up to a massive machine. In fact, this boiler is compact and easy to install in smaller spaces. Speaking of installation, let our staff at Comfortech Service Experts Heating & Air Conditioning in Jackson take care of that for you.
