Product Overview

What Makes NOBLE The Best Combi Boiler?
A GAME-CHANGER IN COMBI WATER HEATING
DELIVERS MORE HOT WATER
It’s sized large enough to quickly meet domesc hot water (DHW)
load. Provides DHW from 2.6 (NKC110) to 4.8 gpm (NKC199) at a
77°F temperature rise.
FASTER DHW RESPONSE TIME
With many combi boilers when you turn on a hot water faucet,
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.”
QUIET OPERATION
Operates so silently that you oen 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 seng up vital system
parameters.

10:1 TURNDOWN RATIO

on/o short cycling at the lowest DHW demands or small heang
demands.
AIR HANDLER INTERLOCK
Prevents cool air circulaon in Hydro-Air installaons when the
appliance is making DHW.
CONSUMER FINANCING AVAILABLE
