Are Navien Water Heaters worth it?
Tankless water heaters are an excellent option for homes today because these models let you wash dishes, take showers and use hot water for other needs without standing around and waiting.
Instead of using a tank, many have coils or a similar design that allows the supply to quickly move across a heat source and come up to temperature fast, and you can usually select the temperature that you want to use. This prevents any scalding or boiling coming out of the tap.
One of the top names in this industry is Navien, which makes both propane tankless heater and designs that work with natural gas lines. You need to make sure that the tankless heater you pick will work with the lines that are already in your home.
Our favorite tankless heater is the Navien NPE-240-A (Check Price on Amazon.com), which comes with a warranty that covers some parts for five years and others for up to 15 years.
It has a built-in pump that keeps the supply circulating inside the heater and continuously moving across the coils to provide you with instant hot H2o almost as soon as you turn on the tap. This tankless heater works with two-inch PVC piping and has digital controls on the front for more natural changing of controls and settings.
How to Choose
What is the Temperature Range?
One important factor to consider is the temperature range that comes with each tankless heater as well as whether it comes set to one specific temperature.
Navien tankless heaters usually come set at a 120 degree Fahrenheit rating, which may be slightly too cool for your needs. While a range of up to 160 degrees Fahrenheit is high enough for most homes, many users will never set the temperature this high. Using a set of around 140 to 145 degrees Fahrenheit will prevent burns and other injuries.
What is the Flow Rating?
Flow rating is a term that manufacturers use to describe the amount of H2o that flows out per minute. Most use a gallon measurement. Many tankless heaters come with both a maximum and a minimum flow rating.
While this may not seem that important to you, it’s essential when you plan on using two supply sources at the same time or one after another. You might need to take a shower and then wash a load of dishes, or you might have two family members who want to make a shower in the morning. A higher flow rate of 10 to 11 gallons per minute will keep your home and family with the necessary amount of H2o.
How Much Power Does it Need?
Check with the manufacturer or read the product description to find out how much power it needs. The volts required will tell you whether your outlets can accommodate the appliance, but it also lets you know whether you need to upgrade your circuit breaker. Upgrading a circuit breaker or a fuse box will add significantly to your installation costs.
Is There an Included Warranty?
Installing a new model can easily cost between $500 and $1,000 or even more, but these products will provide your home with hot water for 10 to 15 years or longer. You should always check the warranty to ensure that it covers all parts and to see how long it will last. Navien offers a warranty that lasts for five years in most parts and 15 years on some of the more expensive parts.
Looking at the warranty will also reveal how much coverage you get. You may find that your warranty only covers parts one time and that any repairs needed in the future must come out of your pocket. It may cover the cost of any new parts but not include the installation of those parts too.
What Power Source Do You Need?
Though you might think that all of these products are precisely the same or quite similar, Navien makes different designs for homes that use propane and those that use natural gas.
Buying the wrong one for your system will cost you more money because you either need to ship the product back or pay contractors to change the system that your home needs. Some people made the mistake of buying the wrong one because they didn’t read the description carefully.
Though the manufacturer occasionally adds an “NG” to the end of a product name to distinguish which ones work with natural gas lines, it often uses the same full product name and model number. Always read through the description to see which one will work with the system in your home.
Top-Rated Picks from Navien on the Market
For homes with existing natural gas lines, this is one of the top options because it works with gas lines of standard sizes.

It comes with features you’ll like, including a digital screen and an intelligent preheating system. This system keeps the temperature at a higher degree, which reduces the time it takes for the supply to reach your maximum setting later.
