Noritz - Tankless Hot Water Heaters

Noritz is proud to feature a product that will not only save you money but will also help the environment by reducing energy use and CO2 emissions. Noritz tankless water heaters are over 80% efficient, they use less energy to operate and emit low NOx emissions with maximum output, making them environmentally friendly. There are many local and regional rebates for installing energy efficient products.

Tankless water heaters in the U.S. market have been increasing in popularity and sales over the past several years. This upward trend will continue to grow as more people learn about the benets of going tankless.

Endless Hot Water

The most popular advantage of Noritz versus traditional tank water heaters is that you will never run out of hot water. A tankless water heater heats water on demand, so that means no storage or shortage of hot water. Imagine the luxury of always having hot showers or filling up a Jacuzzi hot tub and still having an endless supply of hot water for the rest of your household needs. It’s about time your home had an equal supply of hot and cold water.

Properly sized Noritz tankless water heaters are capable of supplying more hot water than traditional tank-type water heaters. With Noritz features such as Quick-Connect and Multi-System, our tankless water heaters can meet any hot water demand on today’s home.

Flexible Installations Options

Compact in design, a Noritz can be installed virtually anywhere. Compared to traditional tank-type water heaters, one of the most obvious diferences is its small size. Indoor or outdoor models are available. This frees up the space formally taken by a bulky tank.

Energy Savings - 50% lower

With a Noritz tankless water heater, you'll save energy and thus, money. Our on-demand systems require no pilot light. Furthermore, according to the U.S. Department of Energy, operating costs could be up to 50% lower since there is no re-heating of water as with traditional water heaters.

Residential Water Heater Models

Choose from the complete line of Noritz tankless water heaters designed for residential use. When properly sized, tankless water heaters provide the comfort of endless hot water to an entire home. All residential tankless water heaters are backed by one of the best warranties in the industry.

Hydronic Boilers

Noritz is the first tankless water heater manufacturer to introduce tankless hydronic boilers. The Noritz NH Series consists of two models, the NH-2001-DV and the NH-1501-DV. These units share the same features as with our other heaters; energy efficiency, environmentally friendliness and of course the water is always hot whenever you need it. Both models are capable of offering nine temperature settings of endless hot water for hydronic heating. These tankless hydronic boilers are dramatically smaller in size, weighing only 66 pounds compared to conventional boilers' typical weight of more than 300 pounds, giving your home more space to enjoy.

Applications

The Noritz NH Series can provide quiet and constant heat to your home by providing hot water to panel radiators, baseboards and radiant flooring. Hydronic heating with the NH Boiler gives a higher level of warmth and comfort than forced air systems because they do not stir up allergens or dust in the home.
