As you should have predicted, heat furnace for daily consumption also comes up with novelty model, which is the non-tank one. You will gather thorough information about Navien tankless water heater in this passage.
This brand is not exactly a new player in the industry. Many homeowners have utilized its varied models in their house with generally satisfying results. Every product has the brand’s general and its model’s specific features. Certain people will find one model to fit their needs perfectly while others might not be thinking like that. Thus, researching Navien tankless water heater reviews from past and current users is quite important.
Why should you purchase heating unit with no tank for your water system, particularly this brand? As stated previously, such unit is environmentally friendly since it does not consume energy unless necessary. Unfortunately, the initial Navien tankless water heater prices are significantly higher if compared to conventional models. Nonetheless, the gain you will be getting is going to outweigh that extra spending.
Before deciding to buy one of furnace models from this brand, you should know what are the features offered by it. This following list will break down some highlight features you will find in its lineups.
Sophisticated Condensing Mechanism
Condensing mechanism has been equipped in all of its lineups. This mechanism is able to work more efficiently than the non-condensing one since exhaust gas produced by the system is providing additional heat. Due to the mechanism, your unit can save up energy up to 98%. User is no longer need to wait for their heated water for a long time.
Inner Re-circulation Arrangement
This particular feature is a built in one in the Advanced lineups. The official name from manufacturer is ComfortFlow. Because of this arrangement, your heat system is able to detect the water flow and prevent incoming water (which is in ambient temperature) to receive the heat. It means that your system does not heat a portion of water that is already tempered.
Durable (and Warranted) Stainless Steel Exchangers
Exchangers are important components in condensing unit. In most models, you will find that the exchangers are made of copper material. However, condensation formed by the system’s mechanism will corrode the copper material quickly. In all of its lineups, stainless steel material is used for the exchangers. It is longer lasting and also warranted for 15 years.
Easy Wi-Fi Control Panel
It is an optional feature offered by the manufacturer. When you add this functionality, a built in Wi-Fi receptor will be added to your unit. There is a certain application made by this manufacturer which allows you to navigate through its control panel virtually. As long as you are connected to the internet, you will be able to control your unit remotely.
All models of this brand can be integrated into a cascading system. It means compiling several furnace units into one cohesive system. Cascading system is particularly needed by places that with high demand of hot water. This system improves efficiency in usage because of the integration of all units within said place.
H2Air Combo Technology
H2Air is another optional feature for Advanced models that combine hot water system with room heating function. Of course, in order to install the unit, you have to adjust the systems in your house to meet its requirements. Proper configuration must be done too for it to run effectively. However, it is definitely a money saving technology to have.
Compare to Other Tankless Brands
Of course, there are other brands that also produce no-tank furnace. However, Navien is still considered a top brand among them. How does this brand compared to others within similar industry?
Above Average Efficiency
When it comes to efficiency, this Japanese brand is without doubt a leading in the market. All of its heated water furnace units have been certified as Energy Star products. Uniform Energy Factor (UEF) ratings for its products go from 0.96 to 0.98; which are way above the market standard.
Wide Size Range
The manufacturer also offers a wide range for unit size. Its options have a range from 150 to 240. Unit’s size is determined by the input and output of each model. Sometimes homeowner installs unit that is not appropriately sized for their house. This might cause inefficiency in energy and budget. Despite that, there are only two series offered.
You get a long warranty of the unit’s exchangers for 15 years after purchase. It is way longer than other manufacturers. This is understandable since the exchangers’ material is highly durable. The warranty only applies if you hire licensed worker for installation.
Unfortunately, if compared to several other brands, there is one downside of its lineups. Users have reported that system issues tend to happen within the first 10 years of usage. The most common issue is leakage.

Installation Factors and Cost
When you are installing one of this brand’s hot water furnace models, the unit’s price is not the only expense that you have to prepare. You should also budget the installation cost which can skyrocket depending on certain factors. In common scenarios, the cost will range from $1,000 to staggering $4,500.
1. Licensed Plumber’s Labor Cost
You cannot avoid employing licensed plumber to do the installation job for one of its models. This is done to avoid potential hazards in the future such as carbon monoxide (CO) leakage in the plumbing system. If you are not working with a recognized professional, your warranty right will be revoked from day one as well. As expected, hiring licensed plumber is pretty expensive.
2. Upgrading System in the House
This particular factor is responsible for increasing the unit’s installation cost significantly. In order to accommodate your new water heating furnace, your house needs to meet the unit’s system requirements. The process might involve setting up a new gas line and increasing the capacity of your electrical service. If your house is old and has dated system, you will be better off adding no-tank unit during renovation.
3. Adjusting the Plumbing’s Routing
When installing a unit, you may also need to adjust the route of your plumbing system. It is done to create better configuration so that your heated water system will be able to operate more effectively and in efficient manner. This job is considered large jobs and you may need to pay more than $500 for it.
4. Supporting Materials
People often overlook this cost component simply because they do not think it is important enough. The plumber will only bring necessary tools to do his jobs while you are expected to prepare the materials needed for the job. It might be costly especially if your plumbing job also includes retrofitting.
