One reason we selected the Navien NPE-240-A Tankless Gas Water Heater as the best tankless water heater from this manufacturer is because it is so much easier to use than the others you might consider for your home. With older or more traditional hot water heaters, there is always a risk that you might turn the temperature up too high, which can lead to boiling hot water coming out of the taps that can burn your kids and other family members. The NPE-240-A has simple arrow buttons that let you adjust the temperature and a screen that shows you the exact temperature selected to reduce the risk of burns and other accidents.
Navien is one of the only companies to create an intelligent preheating technology feature that comes standard on many of its hot water heaters like this model. This feature works in the same way your oven does to slowly increase the temperature inside before you use the water. As the water circulates around inside the heater, it comes up to the temperature that you want in just a few seconds to reduce the wait time that you might otherwise experience.
Designed to work with standard 1/2-inch gas lines, this water heater will also work with pipes of different lengths and can work with PVC vents of up to two-inches in size to safely vent any excess gas out of your home. It also comes with a recirculation pump that keeps the water circulating inside the heater to ensure that it reaches the temperature that you want. You’ll like the stainless-steel heat exchangers that come with this model too because those exchangers do a phenomenal job of heating your water and can last for decades.
Many of the Navien tankless water heaters available share similar names and ID numbers like this NPE-240A, which has the same model number as our number one choice but has a condensing design that makes it a little different. That condensing feature makes the water heater run more efficiently, which can bring an end to your high gas bills. It condenses down the gas in your line to give you more heating power.
The stainless-steel heat exchangers inside last longer than the exchangers made from cheaper types of metal and do a great job of ensuring that water comes out of the heater at the perfect temperature. Once you turn the water heater on, the water will come out of your pipes, pass over those exchangers and slowly come up to temperature before the heater pushes that water through the lines to your bathroom or kitchen. It works with the 1/2-inch gas line(s) that you probably already have in your home and allows you to convert the system to work with your home once it arrives in the mail.
One of the top reasons to invest in this tankless water heater from Navien is because it features intelligent preheating technology that actually begins heating the water before you need it. With other tankless water heaters, you can only use as much water as the heater can provide, which refers to its flow per minute rating, but this water heater increases the temperature of the water earlier to reduce the time that you spend waiting for hot water. It also has built-in connections that work with most gas systems as well a push button controls on the bottom and a digital screen.
While there are a lot of features that you’ll want to look for when picking a Navien tankless hot water heater, you should focus on those with a condensing feature like this Navien NPE-210A Premium Condensing Tankless Gas Water Heater. Condensing features are great for those who want to save money because it allows you to use less gas and still get all the hot water that you or your family needs. This model is great for those who don’t want to sacrifice valuable space either because it’s significantly smaller in size than most other Navien hot water heaters.
We highly recommend the NPE-210A for those who want to cut down on their energy usage because this is an Energy Star rated hot water heater that can help you save money each month, and you may notice a drop in your gas bill the first month after you install it. It is a field convertible hot water heater that comes with two stainless-steel heat exchangers that help water rise to the right temperature faster and send that hot water out to you quicker too. This hot water heater is compatible with 1/2-inch gas lines and will work with lines of up to 24-feet in size.
Our two favorite features on this water heater are its intelligent preheating technology and its digital screen. That screen takes the guesswork out of picking the right temperature and eliminates the worries you might have about turning the temperature up so high that it can cause burns and injuries. With its intelligent preheating technology, you’ll find that you always have water mere seconds after turning on your faucet or tap because this technology allows the heater to increase the water temperature before you touch the tap.
Though this NPE240S-NG tankless water heater has premium right in its name, this is one of the more affordable water heaters from Navien and one that can work with your budget and save you money in the coming years. Designed for use with natural gas systems only, this heater has stainless-steel connections at the top that serve as intake and outtake valves that allow water to move over the heat exchangers inside and then enter your plumbing pipes once the water reaches the right temperature. You can easily select the temperature that you want with the push button controls on the water heater, and the digital screen shows you that temperature too.
Unlike other small tankless water heaters that have just one heat exchanger inside, this Navien model has two stainless-steel exchangers. This allows water to reach the temperature that you selected faster and lets you turn on the faucet and enjoy hot water in seconds. As a field convertible water heater, it comes with everything necessary to convert the system in your home.

This feature keeps the water heater itself at a higher temperature that won’t cause a rise in your energy bills, but this heat allows the water to stay warmer before you turn on the faucet. The preheating feature does a great job of ensuring that you have hot water ready and waiting for you when you reach for the faucet.
With this Navien NPE180S-LP Premium Condensing Tankless Gas Water Heater Propane installed in your home, you can make your propane system really work for you. Designed for use with propane lines only, this hot water heater has an ultra condensing design that significantly reduces the amount of propane needed for everyday heating, which you’ll see on your first gas bill and all other gas bills that you receive in the future.

That is due in part to its intelligent preheating feature. This feature is a type of technology designed by Navien that ensures water in the pipes and lines stays warmer to reduce the time needed to heat that water to the temp you set.
Good reviews from customers is one of the reasons that the Navien NPE-210A-LP Premium Condensing Tankless Gas Water Heater Propane landed a spot on our list of the best models from this manufacturer. As a propane hot water heater, the 210A-LP will work with your existing propane line as well as the vents you have to keep any propane from lingering in the air, though you also have the option of installing a new 1/2-inch gas line and/or a two-inch vent. It also converts easily to work with homes and systems that use another type of gas, but you’ll want to hire a contractor to ensure that it will work with your system.
The Energy Star label found right on the bottom front corner of this water heater lets you know that it will use less of your propane, which makes this a good choice for anyone who wants to save some money. Its compact design also makes it a good water heater for apartments and smaller homes as well as cabins and other structures that use propane.

The water will come out steaming hot or a little cooler based on what temperature you want.
Choosing the temperature is incredibly easy because this hot water heater has the same push buttons that you might find on your favorite electronics.

Though we like many of the features found on this Navien NPE240S-LP Premium Condensing Tankless Gas Water Heater Propane, we put it close to the bottom on our rankings because it has a lower overall rating than some of the other water heaters from Navien that we found. It features a durable seal inside that keeps water from leaking out of the pipes and stainless-steel heat exchangers that can last for a full decade or longer. There are two built-in connections on the top of the water heater that allow water to enter, move across those exchangers and then leave through your water line to reach other areas of your home.
This condensing hot water heater is ready to use and install right out of the box because it works with two-inch vents to safely vent the propane away from your home and with 1/2-inch gas lines.

To save even more, you can even turn the temperature down.
Adjusting the temperature of this hot water heater is as easy as touching the buttons on the front. Hit one button to bring up the current temperature, use the arrow buttons to raise or lower that temperature and view the temperature you selected on its digital screen.

It uses ultra condensing technology to use as little of your natural gas source as possible while still providing your family with all the hot water that they need. The hot water heater comes in a large cardboard box with almost everything needed for installing it in your home inside that box.
This tankless hot water heater features everything you love about the more expensive Navien hot water heaters like an intelligent preheating technology feature and durable heat exchangers. Its two stainless-steel heat exchangers can last for up to a decade or longer and require much less maintenance than traditional boilers or copper heat exchangers do. The preheating feature uses the heat of your home and the warmth of the heater itself to preheat the water inside the line, which allows warmer water to come out of your faucets almost instantly.
Though it will require the use of vents to keep the natural gas moving smoothly, this water heater works with standard two-inch vents, including PVC vents and those made from metal. Navien also designed the NPE210S-NG to work with 1/2-inch natural gas lines. As a low emission hot water heater, this model releases less emissions into the environment and will meet the standards and regulations found in some states.
