Navien’s Journey

Founding and Early Years

Founded in 1978, Navien initially focused on producing environmentally friendly and energy-efficient heating solutions. Over the years, the company expanded its product range and technological capabilities, consistently prioritizing quality and customer satisfaction. This commitment to excellence laid a solid foundation for Navien’s future ventures.

Entry into the Tankless Water Heater Market

In 2012, Navien introduced its line of tankless water heaters, leveraging decades of experience in heating technology. This move marked a significant milestone for the company, seeking to provide innovative solutions catering to modern household needs. Navien’s tankless water heaters quickly gained recognition for their efficiency, reliability, and advanced features.

Features of Navian Tankless Water Heaters

Energy Efficiency

Navien tankless water heaters are designed to be highly energy-efficient, employing advanced technology to deliver hot water precisely when needed. Unlike traditional water heaters that maintain a constant hot water supply in a tank, resulting in substantial energy loss through heat dissipation, Navien’s tankless systems heat water on demand. This on-demand heating eliminates the standby heat loss typically associated with conventional water heaters, assuring that energy is used only when hot water is required.

Navien condensing tankless water heaters enhance energy efficiency through innovative condensing technology. These units capture and reuse heat from the exhaust gases that would otherwise be wasted, significantly boosting their efficiency. This process allows Navien tankless water heaters to achieve ultra-high energy efficiency ratings of up to 0.96 Uniform Energy Factor (UEF), a measure that reflects the efficiency of water heaters in converting energy into hot water.

Being Energy Star certified, Navien’s condensing tankless water heaters meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency. This certification is a testament to their superior energy conservation and environmental protection performance. The high UEF rating means that a larger percentage of the energy consumed by these units is effectively converted into hot water, minimizing waste and maximizing savings on utility bills.

The Heater’s Compact Design Mounts on Walls, Saving Floor Space

One of the standout features of Navien tankless water heaters is their compact design. These units can be mounted on walls, saving valuable floor space in utility rooms or basements. This design flexibility makes them ideal for homes of all sizes. Their sleek and modern appearance also allows them to blend seamlessly into any home decor. The compact size also facilitates easier installation in tight spaces, making it a practical choice for new construction and retrofitting projects.

Advanced Technology Where Homeowners can Remotely Control Their Heater

Navien integrates cutting-edge technology into its water heaters. Features like Wi-Fi connectivity allow homeowners to monitor and control their water heater remotely using a smartphone app. Additionally, Navien units often include advanced sensors and controls that optimize performance and efficiency.

Some models also feature diagnostic capabilities that alert homeowners to potential issues before they become major problems, enhancing their reliability. The smart technology also allows for scheduling and adjusting temperature settings, providing tailored comfort while maximizing energy savings.

Durability and Reliability

Built with high-quality materials and components, Navien tankless water heaters are known for their durability and long lifespan. Many models come with extended warranties, reflecting the company’s confidence in their product’s reliability. This extended lifespan means fewer replacements and less frequent maintenance, providing homeowners with peace of mind and long-term cost savings.

Additionally, the robust design provides consistent performance and efficiency throughout the unit’s life, making it a smart investment for any household. Navian water heaters are built to last. With proper maintenance, these units can last up to 20 years or more, outlasting traditional water heaters, which typically have a lifespan of 10-15 years.

Environmentally Friendly Reducing the Carbon Footprint

Navien tankless water heaters reduce energy consumption, contributing to a lower carbon footprint. Their efficient operation and reduced greenhouse gas emissions make them an environmentally friendly choice. Additionally, the longevity and durability of Navien units mean fewer replacements over time, further reducing waste and the environmental impact associated with manufacturing and disposing of traditional water heaters. Choosing a Navien tankless water heater is a step toward a more sustainable and eco-friendly home.

Benefits of Navian Tankless Water Heaters

Endless Hot Water Supply

One of the primary advantages of Navien tankless water heaters is the continuous hot water supply. Whether you have multiple showers running simultaneously or need to do laundry while washing dishes, Navien assures that you never run out of hot water. This consistent performance makes them ideal for large families and busy households with high hot water demand. Additionally, the system’s rapid heating capabilities mean you don’t have to wait long for hot water, enhancing overall convenience and comfort.

Lower Energy Bills and 34% More Efficient

Tankless water heaters provide hot water on demand, making them more efficient than the most efficient tank-style gas water heaters. As stated by the U.S. Department of Energy, tankless models can be up to 34% more efficient than traditional storage tank water heaters.

These systems eliminate the standby heat losses associated with traditional water heaters by heating the water only as needed. Depending on your usage patterns and the efficiency of your previous water heater, this can result in savings of up to $100 per year on utility bills.

Furthermore, Navien tankless water heaters have a longer lifespan than traditional models.

Space-Saving Feature Also Allows for More Efficient Use

The compact design of Navien tankless water heaters frees up space in your home. This is particularly beneficial for smaller homes or apartments where space is at a premium. By mounting on walls or fitting into tight utility spaces, these units offer greater flexibility in home layout and design. This space-saving feature also allows for more efficient use of storage areas, providing homeowners with additional room for other essentials.

A tankless water heater alone won’t serve its purpose; proper installation is crucial to reap the benefits of your investment. However, installation isn’t the only factor influencing the total cost of a Navien tankless water heater.

Several factors can impact the overall expense, including:

1. Installation Professional installation is necessary to guarantee the system operates efficiently and safely.

2. Venting – Proper venting is essential for removing exhaust gases and can add to the cost.

3. Water lines – Upgrading or modifying water lines might be required to accommodate the new system.

4. Gas lines – Adequate gas supply and possibly upgrading gas lines can also affect the cost.

Professional Installation is a Must

There’s no getting around installation costs for any major home upgrade. Professional installation guarantees the unit is set up correctly and operates efficiently, adhering to all safety regulations and building codes. Additionally, a proper installation can prevent future issues and extend the lifespan of your water heater.

Installation Considerations

Venting to Expel Exhaust Gases Safely

Navien tankless water heaters require appropriate venting to expel exhaust gases safely. Depending on your home’s existing venting setup, this process might involve additional materials and labor. Proper venting provides safety and maintains the water heater’s efficiency.

Water and Gas Lines

In some cases, existing water and gas lines may need upgrading to support the tankless system. This can involve significant work, particularly if your current infrastructure is outdated. Ensuring adequate gas flow and proper water connections is vital for the optimal performance of your Navien tankless water heater.

Considerations Before Buying

Initial Cost

While Navian tankless water heaters offer long-term savings, their initial cost can be higher than traditional or competitor tankless heaters. When considering the overall cost, it’s important to factor in the potential energy savings and longer lifespan.
