The main difference between tankless water heaters and hot water tanks is that tankless models only use energy when you turn on the tap. You aren’t paying to store a huge tank of water while you’re away, at work or at night when you’re sleeping.
Tankless water heaters do cost more to purchase and install than traditional hot water tanks, but you get these main advantages:
For its heating system, Navien uses stainless steel heat exchangers instead of copper (a metal that’s susceptible to corrosion). Stainless steel is corrosion resistant, extending the lifespan of the Navien tankless water heater.
Navien offers the strongest warranty in the industry, including the 15-year warranty on the heat exchanger. They also stand behind their products, providing parts and assistance when needed.
