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, which means it meets or exceeds federal guidelines for energy efficiency. But that’s not all. The GWB9-IH boiler also produces 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? For starters, you could start seeing a decrease in your utility bills. But, you’ll also experience a home that heats up quicker 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 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 to come 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. 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, leave it up to our staff at Winnipeg Supply Service Experts Heating & Air Conditioning in Winnipeg take care of that for you.
