Noble® Residential Combination Gas Boiler
Delivers More Hot Water
Sized large enough to quickly meet domestic hot water (DHW) load. Provides DHW from 2.6 (110) up to 4.8 gpm (199) at a 77°F temperature rise.
Faster DHW Response Time
When you turn on a hot water faucet using many combi boilers, you initially get hot water and then a brief burst of cold water before the hot water resumes. Thanks to its patent-pending control technology, this combi boiler eliminates this cold water “sandwich”.
Prevents Cool Air Circulation
Air handler interlock prevents cool air circulation in Hydro-Air installations when the appliance is making domestic hot water.
Easy to Install and Program
Quickly program the Noble in less than 5 minutes with our Set-Up Wizard that uses plain English – not confusing codes to guide the installer.
