Originally from Japan, the Navien tankless water heater has been gaining a lot of popularity in the United States in the last decade. Even though Navien was founded back in 1978 as a producer of water heaters and boilers, the company has been making a huge bet on innovation, especially in what concerns condensing gas units.
It was only in 2006 that Navien started their operations in the United States. Nevertheless, due to their high-quality products and constant innovations, the company has always been a true success since the beginning.
One of the things that you need to know about the Navien tankless water heater is that all their models are designed as whole-house water heaters and they are gas-fired. In addition, they are all equipped with natural gas. However, in case you want or need, the valve can be easily replaced to burn liquid propane instead of natural gas.
What we like:
There are a couple of things that we really like about the Navien tankless water heater. First of all, they are Energy Star compliant. In the second place, the Navien tankless water heater includes a great residential warranty. After all, you will get a 10-year heat exchanger, a 5-year in parts, and a 1-year labor warranties. Last but not least, all Navien models meet all the standards that ensure reduced noxious emissions.
One of the reasons why Navien can provide such warranties is because all their models are made of dual stainless steel. So, this prevents corrosion.
While all Navien tankless water heaters tend to work well, the truth is that you may require a more advanced model. In this case, you will be glad to know that Navien also has these advanced models available. These type of models include a timer so that the pump isn't always reheating the water or recirculating when there is no need. In addition, these models also feature the Comfort Flow technology, which include the buffer tank and the recirculation pump.
These more advanced Navien tankless water heaters tend to work in a different way. The truth is that they maintain just a small amount of heated water in the tankless unit. Ultimately, this decreases the time as well as the amount of water wasted when you are waiting for the hot water. However, note that this also adds an extra energy cost.
As we already mentioned, Navien makes a strong bet in innovation. So, in case you want to be in control of your Navien tankless water heater, you can get the NaviLink add-on. This add-on allows you to use WiFi so that you can be in control of the water heater as well as you can do remote monitoring. This add-on is usually available for $200 - $225.
Another powerful technology that the Navien tankless water heater includes is the cascading. This technology allows you to have up to 16 units linked together or 8 when you are using a common vent. This technology is meant for larger homes as well as for other commercial applications where you may require a large volume of hot water.
In case you want to make sure that you have hot water immediately available, you can also buy the Navien HotButton which is an optional accessory. This accessory needs to be installed near the bathroom. While the accessory only costs you around $80, you will need to pay more for the installation. It tends to cost between $150 and $300.
As you already know, Navien has a lot of different Navien tankless water heater models. In the case of the Navien Advanced Series units, the H2Air Kit option is included in the space heating. In this case, the hot water runs through a kind of radiator that is usually located in an air handler or in a furnace. Nevertheless, we have to say that this heating method may not be as effective in terms of cost as others. After all, between the equipment itself and the installation, you should expect to pay at least $1,500.
The Navien Advanced Series water heaters also allow you to have a remote. Please note that this is optional. With this remote, you will be able to control the recirculation timer, the water temperature, among others. This remote usually costs between $75 and $85.
What about the competition?
The truth is that there are a lot of brands on the market. Some of the most popular include Rinnai, Takagi, and Noritz. However, one of the best things about Navien is that it accommodates to any home size as well as to any hot water demand. In addition, Navien is usually considered one of the best brands since all their models are condensing gas heaters and they usually have a great efficiency.
While so far we haven't seen almost any negative aspect related to the Navien tankless water heater, the truth is that around 20% of their tankless heaters have a lot of mechanical issues in the first 10 years. These include failed control boards and leaks. While the Navien tankless water heater comes with a 15-year warranty, it is incredibly important that you hire a certified installer for the work. I case you don't, repairs won't be covered and your warranty will be voided.
What about Navien's prices?
We can definitely say that Navien's prices are competitive and they reflect a good combination of quality and performance. They are clearly able to compete with other popular brands such as Rinnai and Rheem.
In case you were already checking the Navien tankless water heater prices, you probably already saw that prices vary depending on the seller. Usually, when you see a seller charging more, this usually means that the shipping cost is already included. So, it is always a good idea to find a seller near you so that you can decrease your costs.
In case you are looking for the Navien Advanced Series units, then you need to know that they are pricier since they have built-in recirculation pumps.
Overall, when you are considering buying a Navien tankless water heater, you should expect to pay anywhere between $875 and $1,500.
