Navien stands out from its rivals due to its combination of a water heater and a hydronic system boiler.

Besides needing a greater energy output, tank water heaters also have other problems, such as proper ventilation, debris accumulation, and other issues that make Navien products a great option.

Navien NCB 240 Review: Things To Consider Before Buying

Navien combo boilers are an excellent way to upgrade hydronic heating systems in residences, condominiums, apartments, or business offices and provide hot water on demand. The machinery is constructed with high-quality materials to ensure a long-lasting lifespan.

The installation of Navien’s residential, wall-mounted water heater is enhanced by its heat exchanger system, as well as the easy-to-install venting and water line connection points.

When homeowners need a heating system that is highly efficient and also provides hot water on demand, this design works excellently in fulfilling both requirements. Because the NCB 240e is both a boiler and a heater, the engineering needed to build it is more intricate, yet the setup has been simpler.

Homeowners skilled in DIY projects can install HVAC systems themselves. Still, you can hire a professional to ensure the process is done correctly and avoid potential issues.

Navien NCB 240 Review: Social Proof & Reviews

Both good and bad remarks were given concerning the Navien NCB 240 review. Examining the feedback and opinions of people who bought the Navien Boiler combo on the web made me anxious. Here are a few illustrations: 

One of the reviewers considered Navien NCB a good deal in the plumbing & heating business. Another reviewer claimed that you need a licensed plumber for troubleshooting issues.

One reviewer shared that he has read many negative comments about early Navien products. The initial products’ root causes can be either defective components or inadequate installation and lack of problem-solving knowledge among plumbers and DIYers.

Thankfully, his decision is an exemption to the unfavorable feedback since you had the structure set up two months ago and are currently using it to keep warm in the winter season. In addition, the heating is perfect and silent. The product is cutting the monthly gas bill in NYC.

In conclusion, the reviews of Navien’s product vary drastically, so it is best to have a professional install it. Additionally, it is essential that those who have recently acquired the system read the Owner’s Manual carefully before using it.

Navien NCB 240 Review: Competitive Comparison

The Navien tankless hot water product has so many modern features that it wouldn’t have many other challengers in the market.

Nevertheless, a few products almost identical to the Navien NCB household hot water system are available.

Stiebel Eltron Tempra Plus

The Hydro Shark® Modular Panel hydronic water heating system offers hot water for central heating and hot running water from the tap. This system necessitates more space on the wall due to the combination of two discrete components, a hot water boiler, and an inline water heater.

The expense of a Stiebel Hydro Shark® is similar to that of a Navien NCB 240e, depending on the size of the space that needs heating. The Hydro Shark® is available in both natural gas and electric-powered versions.

Rinnai RUR

Rinnai offers a wide selection of tankless domestic hot water boilers and in-line heaters. The RUR product range contains small-scale and large-capacity systems, all of which come with stainless steel heat exchangers such as the NCB 240.

Rinnai items are available in more petite and concise shapes, and some can be put on the outside of a construction. Prices for the products are similar.

Ecosmart Eco 27

The Ecosmart domestic water heater has a high capacity and can warm up to 6.5 gallons of water in a single minute. This apparatus was not created to be a typical boiler unit. Instead, it was engineered to be a whole-house tankless hot water system.

An Eco 27 would require installing a new hydronic boiler system, which would require additional wall area. In addition, the Eco 27 tankless heater for residential use is more affordable than the Navien NCB 240 because it has limited functionality in regulating the temperature in the home.

  1. NAVIEN NCB-240/130H. Installed by professionals on 3/20/2024. First day 3 error messages. They were removed by the Pro, but appeared again a week later. The hot water on demand is questionable, probable due to the error messages. It takes more than 4 minutes to reach the required water temperature @ the kitchen sink. The radiant in floor heating system appears to be working fine. Pro kept assuring me to give the computer time to acquire our usage routine. 4/18/2024, finally had Pro check out the error messages. Pro determined that defective parts need replaced. He will order and replace defective parts when they arrive. Fortunately the heating season is behind us, but wasting running water before the required water temp to wash dishes is not acceptable.
    What happens if the replacement parts do not solve the problem? Hopefully they will.
    I will keep you advised.
