Real Navien Boiler Review Data

Customers who have installed Navien boilers in their homes love that they’re quiet systems that run well. They’re energy efficient and can help save on heating costs, have some great features, and are reliable. However, professional installation and regular maintenance by a licensed HVAC technician is critical, otherwise problems and breakdowns can happen more frequently than they should.

Navien Average Boiler Price Range

$4500 – $10,000+ including installation

It’s impossible to give an accurate estimate of the cost to install a new boiler because so many things play into the price. The cost of the boiler alone will vary based on factors like capacity, (which depends on the size of your home), how many zones there are, what special features the boiler has, the efficiency of the unit, and the type of boiler.

All Navien boilers are condensing—even the combi models—and these tend to be the most expensive boiler types because of their efficiency and size.

However, one of the biggest things that will influence the final price of your new boiler is installation, which can range between $1,700 and $3,700 or more. Installation costs can fluctuate based on:

• The make, model, and brand
• Boiler style (such as conventional versus combi)
• Size and capacity of the system
• Number of zones
• Your current heating infrastructure

You can save money on the cost of your boiler by looking for rebates, which are sometimes available from utility companies, local HVAC distributors, the government, and directly from the manufacturer.

ENERGY STAR certified boilers like Navien’s may cost a little more than standard ones, but they also use 10% less energy.  

Navien Boiler Options Reviewed

Condensing Boilers: NFB-H Series and NHB-H Series

The NFB-H Series and NHB-Hseries are high-efficiency condensing boilers with AFUE ratings of 95 percent. Because they’re condensing boilers, they trap and recycle some of the heat that would be lost with a conventional boiler, thereby improving efficiency and heating performance.

These models are also equipped with Navien’s sophisticated burners, which have some of the highest turndown ratios in the industry. They are compact and designed to be easy-to-install, and this could mean lower initial setup costs.

The boilers in this series are compatible with NaviLink, a Wi-Fi enabled control that can give you access to your heating system from anywhere in the world.

Condensing Combi Boilers: NCB-H Series and NFC-H Series

It used to be that you had to choose between combi boilers and condensing boilers, but Navien was one of the first brands to offer the high-efficiency condensing combi boiler with their NCB-H Series and NFC-H Series models.

Not only can these boilers provide heat for your home and hot water for all your cooking, cleaning, and bathing needs, but they’re also more energy efficient because they recycle exhaust gases that traditional combi boilers might waste. 

The boilers in these series are high-quality and designed to last, and when paired with the NaviLink system, they can let you adjust settings for your heating and hot water systems remotely.

Navien Boiler Review: Top Models Compared

NHB-H Series

The NHB-H boiler is a wall-hung boiler that comes in four sizes. They all have an industry-leading turndown ratio of 15:1, so they can operate at a very low capacity to save fuel and money while still keeping your home at the perfect temperature. These models are designed for fast and easy installation, have built-in zone control, and can be cascaded with up to 16 units. The NHB-H series boilers also come equipped with the NHB Integrated control, and can be paired with NaviLink for convenient Wi-Fi control over your heating system from anywhere in the world.

Navien Exclusive Features

Feature 1 – NHB Integrated Control

Feature 3 – NaviClean

NaviClean is a proprietary magnetic boiler filter that filters the water in your boiler system using the power of magnets. Boiler filters have many benefits, like improved efficiency, lower maintenance requirements, increased longevity, better flow rate, and fewer obstructions in the system.

Navien’s Boiler Warranty

Any good Navien boiler review will discuss warranty terms. A good boiler warranty is important for two main reasons: it can save you plenty of money on repair costs, and it can give you an indication of how reliable the system will be.

If a manufacturer only guarantees their product for a couple years, then it might be because they don’t expect it to perform optimally beyond that. By contrast, if a boiler or its major components are warrantied for several years, it’s because the manufacturer expects them to last at least that long.

Navien stands by all their products with a good warranty, but the specific terms change a little depending on the series:
