Hot Water On Demand from Noritz

Energy consumption is certainly on everyone’s minds these days as prices in the U.S. fluctuate daily. Manufacturers know that this is a concern for consumers and are responding with product offerings that span from cars to energy-efficient appliances. Noritz is one of those companies that have brought its tankless water heating technology to the U.S. market.

With our November issue of Qualified Remodeler, we introduced you to Noritz in a story on energy-conserving water products. Noritz was started in Japan in 1951 and, after finding success there with its tankless water heating products, set up shop in the U.S. marketplace in 2001. Now, Noritz manufactures 1.3 million tankless water heaters for the global market yearly.

“There is this misconception of having instantaneously hot water with a tankless water heater,” says Brian Watts, Noritz America Corp. national sales manager for builder accounts. “Although a tankless heater will heat instantly, you still have to run the water through the pipe which is something people forget sometimes.”

According to Watts there are four main advantages to having a tankless water heater in a home. First, it provides an endless hot water supply that doesn’t run out after long-term use. Second, there is an energy savings of between 30 to 50 percent over a gas heated system. Third, it is a system that produces hot water on demand and does not fire up all day to keep water hot. Lastly, Noritz tankless water heaters are roughly the size of a carry-on suitcase, which amounts to space savings, and has the advantage of being placed indoors or outdoors in some areas of the U.S.

“The replacement market is where a majority of our sales are coming from right now,” says Watts. “Builders are using it more and more as green building programs push this, but remodelers and contractors are our driving force, as well as consumers asking for them more.”

One thing that Watts point out is the need to make sure that a tankless water heater is properly sized for a home. This depends not only on house size, but also the hot water needs of a home.

“Wrongfully sizing a home with a small heater will cause problems and give the home-owner a bad impression of tankless systems,” says Watts. “That’s why it’s important not to just grab the cheapest system out there since they are priced by size.”

Currently Noritz products in the U.S. are based on their Japanese counterparts. With the success they are having, Noritz is now working on developing products specifically for the U.S. market and its consumer.
