Noritz Tankless Water Heater: Top 5 Models

Noritz is a water heater manufacture that has been making products with revolutionary product designs against a pioneering technological backdrop. The company’s vision has always been toward saving the environment from harmful emissions involved in water heating. Through continuous research and development, Noritz has built a water heater product that uses tankless technology.

So what’s tankless water heater technology? It is a flow-through water heating technology that uses no tank to store the water. This is because design of storage-tanks inhibits water heat capture when not in use. So actually you end up spending more on heating and re-heating. Because once heated, the water in the tank might cool off. But with tankless water heating technology, you don’t have this situation.

The following are 5 top tankless water heater models from Noritz.
