Hydronic Heating Benefits
Comfort, Silence and Economical Heating
The radiant heat allows for heating from the floors to the ceiling for overall comfort.
Since no blowers are needed to transfer heat, your home can be warmed up nice and quietly.
Even after the boiler is turned off, the radiant heat from the floors continues to transfer throughout your home for hours.
The Navien NCB is rated at up to 98 EF, or 98% efficient for top energy efficiency in a gas boiler.

Dual Stainless Steel Heat Exchangers
Extended Life & Highest Flow Rate
Old boilers typically used copper heat exchangers. Since your heat exchanger is doing all the work, it needs a stronger material to handle the load for years to come. Stainless steel is the optimal material to resist corrosion.
The unique stainless steel flat plate heat exchanger creates the highest flow rate for domestic hot water of any combi-boiler in the industry, 4.5 GPM @ 77 degrees.
Leak Detector Accessory
Your Safety in Mind
The leak detector feature detects the first sign of water to prevent damage to your water heater or personal belongings.
Strong Anti-Freeze Feature
To Prevent Frozen Pipes
Prozen pipes in the winter can be costly and leave you cold with no heat. The Combi’s built-in Control system was engineered specifically to withstand colder conditions.
Other Features of the Navien Combi-Boiler
Environmentally Friendly Low NOx Emissions
Qualified for Utility Rebates
Can run on natural gas or easily convert to propane
80% smaller size than a traditional floor standing boiler or tank water heater, truly space saving

What are some gas boiler replacement warning signs?
Your gas boiler may be beyond repair if:
20 years+ old
If your boiler is over 20 years old, it is running on borrowed time and not very efficiently at that.
Hissing is associated with iron or sludge caught up in the system causing it to heat up and shut down. This may be a simple repair, but if left unattended for long enough, it could mean the end for your boiler.
Leaky water may just be a service or repair but like “Noises” you should get this checked out before it’s too late.
What are the advantages of radiant heating?
Consistent comfortable heat
Radiant heating, aka hydronic heating, provides a more consistent comfort than a forced air system. Hidden radiant systems use piping inside of floors, ceilings, and walls. The combi boiler allows you to heat your water and your whole home at the same time.
In a forced air heated house, you might have a large variation between the temperature at the floor and up higher in the room. Houses heated with radiant systems tend to have uniform temperatures throughout each room. No wonder these systems are so popular in Seattle.
