Tankless Water Heaters

It is worth switching to a tankless water heater if you are looking for a more efficient option. Tankless water heaters can save you money on your energy bill, and they can also have a longer lifespan than traditional water heaters.

Navien tankless water heaters have a lifespan of up to 20 years. However, proper maintenance is required in order to achieve this lifespan.

To choose the right size tankless water heater for your home, you will need to consider a few factors, such as: the number of people in your household, the average water usage in your household, and the climate in your area. Use our Navisizer tool to quickly find the right model for your home or business.

Condensing tankless water heaters need a condensate drain. This is because when the water is heated, it produces condensation that needs to be drained away. The condensate drain ensures that this doesn’t build up and cause problems with the tankless water heater. Non-condensing tankless water heaters do not need a condensate drain.

Descaling is a process that removes mineral deposits from the inside of the tankless water heater. It’s something that needs to be done yearly, unless you have very soft water.

Installing a Navien tankless water heater is best done by a licensed plumbing contractor professional because it involves disconnecting and reconnecting gas lines. Venting and wiring also require professional expertise to ensure the installation meets building codes. Use Navien’s installer and service locator to find a specialist in your area.

A Navien tankless water heater must be purchased and installed by a licensed plumber. Find a Navien installer near you.

Navien tankless water heaters only require 2-4 Amps to run, and don’t need a dedicated electrical line. All Navien tankless water heaters have a factory-installed 3-pronged (grounded) plug and can be plugged into any grounded electrical outlet nearby.

Yes, you can leave your tankless water heater on all the time, because it’s designed to only heat water when needed. 

Unlike traditional water heaters with tanks, tankless models don't store water, so they don’t consume energy unless there’s a demand for hot water. This makes them both highly energy-efficient and suitable for continuous use. 

Navien tankless water heaters have an optional NaviLink Wi-Fi system that lets you monitor and control your water heater from anywhere using your smartphone, for the ultimate peace of mind.

No, you can install a tankless water heater on an inside or an outside wall. Navien offers both indoor and outdoor tankless water heaters, as well as units that work in both settings.

If installed indoors, you can install your tankless water heater on either an interior or exterior wall, depending on where you have space. It’s preferable to mount your indoor  tankless water heater to  an exterior wall if possible, to reduce the length of vent piping.

Navien tankless water heaters are silent when not in use. When producing hot water, your tankless water heater will make a low, steady humming sound comparable to a refrigerator running. 

While tankless water heaters are often referred to as instant tankless water heaters, there is no water heater that delivers hot water instantly (with zero delay). Tankless water heaters do provide endless hot water on demand in a matter of seconds.
