The CB Series of Combination (Combi) Boilers from Noritz is a year-round, whole-home solution that utilizes high-efficiency condensing technology to deliver hot water to both plumbing and hydronic heating applications, including those in colder climates.

The CB Combi performs at a 95 percent AFUE (Annual Fuel Utilization Efficiency); that is, 95 percent of the Btuh input is converted into useable heat, making it an extremely energy-efficient appliance. This fuel-saving performance meets “Energy Star Most Efficient” standards, which represent the EPA’s highest efficiency rating and allow homeowners to qualify for various state energy rebates.
