Common Questions About Noritz Water Heater Installation & Service


Tankless heaters don’t store hot water — they heat it as you use it. That means no more running out of hot water during back-to-back showers. For more information, visit our Tankless Water Heater Page.


Nope — it means endless, not instant. You still wait a few seconds for hot water to reach your faucet, but once it starts, it won’t run out.


Cold water flows through high-powered burners or heating elements, warming it instantly as it moves through the unit — instead of sitting in a big tank.


Noritz tankless heaters are built to last up to 20–25 years with proper maintenance — nearly double the lifespan of a traditional tank heater.


Yes. An annual flush and inspection will help prevent buildup, protect your warranty, and keep your unit running efficiently. We can handle that, too.


Most installations range from $4,700 to $8,300, depending on your home setup and model. We offer upfront pricing and financing options to fit your budget.
