At ProMax Water Heaters & Plumbing, we understand the importance of having a reliable and efficient water heating system in your home. Navien tankless water heaters are a popular choice for many homeowners due to their advanced technology and energy efficiency. But how exactly do they work? Here’s an in-depth look at the operation and benefits of Navien tankless water heaters.

On-Demand Heating

Unlike traditional tank water heaters that store and continuously heat a large volume of water, Navien tankless water heaters heat water on demand. When you turn on a hot water tap, cold water travels through a pipe into the unit. A gas burner or electric element heats the water as it passes through the heat exchanger, delivering a constant supply of hot water. This means you’ll never run out of hot water, no matter how many showers, dishwashers, or washing machines are running simultaneously.

Energy Efficiency

One of the primary advantages of Navien tankless water heaters is their energy efficiency. Since these units only heat water when it’s needed, they avoid the standby energy losses associated with traditional tank water heaters. This on-demand heating process can result in significant energy savings, reducing your utility bills and lowering your home’s environmental footprint.

Condensing Technology

Navien tankless water heaters utilize condensing technology, which further enhances their efficiency. This technology captures and reuses the heat from the exhaust gases to preheat incoming cold water. As a result, these units achieve an impressive energy factor (EF), often exceeding 0.95, making them one of the most efficient water heating options available.

Advanced Controls and Connectivity

Navien tankless water heaters come equipped with advanced controls and connectivity features. Many models offer remote control capabilities, allowing you to adjust the water temperature and monitor the system’s performance from your smartphone or tablet. This added convenience ensures you can maintain optimal water temperatures and quickly address any issues that may arise.

Space-Saving Design

Traditional water heaters can be bulky and take up valuable space in your home. Navien tankless water heaters, on the other hand, are compact and wall-mounted, freeing up floor space for other uses. Their sleek design makes them ideal for homes with limited space or for installation in areas like closets or utility rooms.

Durability and Longevity

Navien tankless water heaters are built to last, with high-quality materials and robust construction. They have a longer lifespan compared to traditional tank water heaters, often lasting over 20 years with proper maintenance. This durability means fewer replacements and long-term cost savings for homeowners.
