    Noritz – CB180 Combination Boiler Water Heater

    Noritz CB180 Combination Boiler is a year‐round, whole‐home solution that delivers hot water to both plumbing and hydronic heating applications. The unit performs at a 95 percent AFUE (Annual Fuel Utilization Efficiency); that is, 95 percent of the fuel consumed goes to heating the water to the preset temperature, as opposed to being lost through the flue.

    This fuel‐saving performance meets "Energy Star Most Efficient" standards, meaning that, with the Combination Boiler, you will be able to qualify for various state energy rebates around the country and offset the initial cost. The CB180 has a maximum input Btuh of 180,000 for hot water and 100,000 Btuh for space heating.
