World Water Day: Tankless Water Heaters Working for Every Last Drop


Today is the 24th annual World Water Day recognized by UN-Water, the United Nations’ entity that coordinates the UN’s work on water and sanitation. The holiday stands as an opportunity to learn more about water-related issues and to inspire others to make a difference in water conservation.

Did you know that the average American family of four uses 400 gallons of water per day, according to the U.S. Environmental Protection Agency? On average, approximately 70 percent of that water is used indoors. In mid-December of last year, the White House administration stated at its “Roundtable of Water Innovation” event that it believes the country can reduce its water usage by 33 percent just by taking simple measures like turning the water off when you brush your teeth.

A large portion of water used in homes is wasted when people allow water to run down the drain, waiting for it to get hot. Sounds like a problem that needs a simple fix - less wait time for hot water. In an effort to conserve that initial water, tankless water heaters have the answer, allowing for a new construction or retrofit recirculation solution with or without a dedicated line to provide faster hot water whenever and wherever you need it.

Our company, Rinnai America, the number-one selling brand of tankless water heaters in the U.S. and Canada, has engineered new systems that truly pay off at the faucet:

  • The Ultra Series Tankless Water Heater RUR Models provide faster hot water provided by an integrated recirculation pump and internal bypass line (RUR models) with or without a dedicated return line that provides heated water during active circulation periods controlled by a timer, making hot water rapidly available in shower, sinks and appliances – avoiding water down the drain waiting for hot water.
  • Our upcoming Wi-Fi module uses wireless technology so that users can control their tankless water heaters from a smartphone or tablet to turn the system on and off, change the water temperature, monitor status and will soon activate the recirculation system.

The typical U.S. home wastes potentially thousands of gallons of water annually. By creating a simple solution that reduces wait time for hot water, consumers can use the right amount of water without waste, gaining a significant head start on the president’s goal of reducing water use by 33 percent.
