From the many reputed tankless water heaters out there, the name Navien stands out a lot, especially when we talk about gas/propane tankless units.
Founded at the end of the 70s, the Japanese brand makes high-quality boilers and water heaters and truly is an innovator with the condensing gas units category.

We should start by highlighting that all Navien tankless water heaters are gas-fired and designed to sustain a whole house. They come prepared for natural gas, and it’s not tricky to replace the valve for burning liquid propane.
Navien tankless water heaters are Energy Star compliant, which says a lot about the energy efficiency and performance. They meet standards for reduced noxious emissions and come with a warranty for the heat exchanger and other parts.
The NPE-Advanced models feature a recirculation pump and a buffer tank, and the ComfortFlow technology is nothing new anymore. The units come with a timer so that the pump doesn’t recirculate nor reheat water when nobody taps the hot water. The system simply collects a tiny amount of heated water in the tankless unit and the pipe that travels to the appliances. This way, the waiting time and wasted water are significantly reduced.
On top of everything else, all Navien units include cascading technology. Therefore, you can connect up to 16 units together. You can use a standard vent when linking eight units, which is an excellent scenario for high hot water demand applications, commercial or residential.
What are the prices?
The prices for Navien tankless water heaters start at $1,000 and don’t go higher than $2,000, with $1,650 being one of the highest costs to see.
You may add or have particular features for your Navien tankless water heaters, so here are some costs that may increase the final price of your unit:
- You can add-on a feature that enables Wi-Fi for remote control and monitoring of the water heater. You pay $200-$225 for the Wi-Fi control, which comes built-in in units from the Navien’s opponents.
- Don’t skip checking the Navien HotBUtton, which is an optional accessory that you may use remotely (it can be next to a bathroom). The button can activate internal recirculation from the unit to the faucet, making hot water immediately available. It only costs around $80, but the installation can range from $150 to $300.
- The units within the Navian Advanced Series come with space heating thanks to the H2Air Kit option. Hot water will be circulated to a heat exchanger (similar to a radiator), placed in the furnace or air handler. The water heater’s blower will pull air over the heat exchanger, and the hot air will travel through the ductwork. It’s innovative, even if we’re still debating if it’s cost-efficient or not. You may have to take more than $1,500 out of your wallet for both the equipment and the installation.
- The Advanced Series include an optional handheld remote that lets you control and checks all the functions, recirculation timer, and water temperature included. You can get it for $75-$85.
What’s the final spending?
You shouldn’t undermine the costs for the installation, which can range from $575 to $1,500. Several aspects affect the price for installation, and here are some of them:
- Installing a new gas line
- Venting the unit
- Adding a recirculation water line to a water location
Even if you’re the DIY type a customer, you should talk to a licensed plumber for installing your Navien tankless water heater. Improper installation may alter the performance and durability of your unit, and even lead to dangerous gas/carbon monoxide leaks.
