The Leader in Condensing Tankless Technology

In 2006, Navien, Inc. was established to open new markets in the United States and Canada for parent company KD Navien. Navien has since become one of the fastest growing companies in the home comfort sector in North America, providing condensing tankless gas water heaters and condensing combi boilers. Navien’s products possess state-of-the-art technology, high efficiency and reliable quality, making it the leader in the marketplace for tankless technology.

Navien has achieved international recognition for its sophisticated engineering and robust designs. Backed by more than thirty years of experience with advanced water heating technology, Navien will continue its mission to provide high quality products that are beneficial to both customers and the environment.

Navien Water Heaters

Energy Factor & Heat Exchanger

The average Energy Factor is 0.82, however, Navien water heaters have an extremely high Energy Factor that ranges between 0.95 to 0.97. This is the result of the condensing technology that uses the flue heat to increase the temperature of cold incoming water in one of the two stainless steel heat exchangers. The NPE series is the most efficient tankless water heater in the industry, with ultra condensing technology that delivers cooled exhaust gas and high performance up to 0.98 EF.

Due to the high quality of heat exchangers, Navien provides a 15-year warranty. The heat exchanger is made of stainless steel and is the place where the main burner is heating water. The stainless steel allows the longevity of the unit, economical and reliable work, and also resists corrosion better than copper to provide longer life.

Venting

All Navien water heaters are designed as the indoor – direct and non-direct vents and outdoor models that use 1/2″ gas connections and 2″ PVC venting. This can help to cut the installation time in half. As the heat is “stolen” from the flue gasses, its temperature gets lower so it exits the vent pipe with lower temperature than the conventional tankless units making the venting system economical and easier to install. The indoor-type water heater utilizes the concentric and two pipe system, installed horizontally or vertically, with the length up to 100 feet.

 Burner 

There is an eco-friendly gas burner designed to allow a dramatic reduction in CO2 and NOx gases mainly due to the optimal premixing of the air and gas.

 Water Flow

 Navien water heaters from the “A” series are designed with the ComfortFlow technology so no minimum water flow is needed for the units activation. These models are equipped with the recirculation pump and 0.5 gallon buffer, so the temperature fluctuation is reduced and comfort is increased.

 Model Selection

Navien designs two types of water heaters including gas and combi-boilers. The gas tankless water heaters are available as the NPE series. These are used for heating portable water only. The gas combi-boilers are also designed for home space heating.

 Navien NPE-Standard Series

Some advantages to consider:

  • More output for the money. With high efficiency condensing technology, NPE-S units deliver more BTUs where it counts, resulting in greater flow rates than comparable units.
  • Lower installation costs for you. You can typically install a NPE-S in half the time of other tankless units — usually within 4 hours, with more flexibility and lower material costs.
  • Lower operating costs for the homeowner. Industry leading 0.99 EF can save you more on the yearly operating costs.

Why Tankless?

 

Tankless water heaters take up very little space, can be mounted on any exterior wall, and offer nearly endless hot water. Since Navien Condensing tankless water heaters only provide hot water when you need it and can provide an endless supply of hot water, you never have to worry about running out of hot water no matter how many hot water draws you have in a row.

 

A tankless water heater can be powered by electricity, natural gas, or propane. Depending on your location and what resources are available to you, you want to try and go with the more economical choice and determine what is most likely going to save you more money in the long run.
