Product Overview

With efficiency ratings of up to 83% AFUE, the GWB8-150E-3 offers significant energy savings compared to an older, less efficient boiler. That means you’ll see lower utility bills throughout the winter, even without adjusting your thermostat.

  • Vent Damper: Automatically closes when the boiler turns off to maintain energy efficiency.
  • Cast Iron Heat Exchanger: Designed for years of long-lasting reliability over a range of water flow rates.
  • Thick Fiberglass Insulation: Minimizes heat and energy loss when the heat exchanger cools down after a cycle.
  • Electronic Ignition Control: Monitors water temperature and maximizes efficiency by turning on the burner only when needed.
