The NOBLE™ combi boiler provides a space-saving choice for builders and specifiers, lowering installation costs by reducing the mechanical equipment needed to provide rapid, reliable hot water supply and efficient space heating. It also gives plumbing contractors a money-saving alternative for single family housing with 1 or 2 bathrooms. DELIVERS MORE HOT WATER: It’s sized large enough to quickly meet domestic hot water (DHW) load. Provides DHW from 2.6 (NKC110) to 4.8 gpm (NKC199) at a 77°F temperature rise. QUIET OPERATION: Operates so silently that you often have to look at the user-friendly interface to see if it’s running. EASIER TO INSTALL AND PROGRAM: With our Set-Up Wizard, you can program the boiler in less than two minutes. The user-friendly interface uses real words—not confusing codes—to guide the installer in setting up vital system parameters. BETTER TECHNICAL SUPPORT AND TRAINING: Answers are accessible whether online or on-campus. LochinvarU.com is always on, 24/7 for technical support. And Lochinvar University is the industry’s best-equipped training center. 10:1 TURNDOWN RATIO: Operates as low as 10% of the maximum firing rate, preventing on/off short cycling at the lowest DHW demands or small heating demands. AIR HANDLER INTERLOCK: Prevents cool air circulation in Hydro-Air installations when the appliance is making DHW. CONSUMER FINANCING AVAILABLE: Check with your local Sales Representative for additional information.
