Navien Tankless Water Heater Installation: Costs, Timelines, Warranty, and More

When considering upgrading to a tankless water heater, Navien is a name that frequently comes up due to its reputation for efficiency

When considering upgrading to a tankless water heater, Navien is a name that frequently comes up due to its reputation for efficiency and reliability. If you’re contemplating making this switch, you likely have questions about costs, installation time, lifespan, and warranty. Here’s a detailed Q&A to guide you through everything you need to know about Navien tankless water heater installations.

What is the average cost of a Navien tankless water heater installation?

The cost of installing a Navien tankless water heater can vary widely, primarily depending on the model of the unit and the complexity of the installation process. A direct replacement of an existing tankless water heater with a new model tends to be more cost-effective. Conversely, transitioning from a traditional water heater tank to a tankless system is usually more expensive. This is because the latter requires extensive work, including the installation of new vent pipes, gas lines, and water tubes. The range in cost can be broad, reflecting these differences in requirements.

How long does it take to install a Navien water heater?

The time it takes to install a Navien water heater can vary, but typically, a professional installer will complete the job within 2 to 6 hours. This timeframe can fluctuate based on several factors, including the complexity of the installation and whether it’s a replacement or a new install. The efficiency of tankless water heater installations means you could potentially have your new system up and running in less than a day.

What is the life expectancy of a Navien water heater?

Navien water heaters are known for their durability and longevity, thanks to their high-quality materials and advanced engineering. On average, a Navien water heater is expected to last between 15 to 18 years. This lifespan can be influenced by various factors, including maintenance routines, usage patterns, and water quality. However, Navien’s commitment to quality ensures that their units are more than capable of reaching, if not exceeding, this average lifespan.

What is the warranty for a Navien water heater?

Navien provides comprehensive warranty coverage for its tankless water heaters, which includes:

• Parts Warranty: 5 Years

• Heat Exchanger Warranty: 15 Years

• Labour Warranty: 1 Year
