Installation costs on tankless heaters have come down recently, and Noritz offers models that are compatible with the same gas line and ventilation stacks as traditional heaters. Plus, Noritz can help you find a licensed installer wherever you live. That means the two heaters are now much more evenly matched. But after installation, the difference is clear:rs:

Tank Heaters are old technology, and they have flaws. Minerals build up inside the tank as it’s cooked over and over. Most tanks last only 10-12 years before they have to be replaced, and typically come with just a 6-year warranty.

Tankless Heaters are modern and more effective. They last up to 20 years with very little maintenance. And Noritz backs most water heaters with a 10-year warranty or longer.
