A tankless water heating system heats water on demand, when you need it.The concept behind this technology is very simple to grasp. A tankless system differs from the traditional tank-style water heater in that a tank-style system heats water and stores it until it is needed. Tankless water heaters have been popular in Europe and Asia for several years, but did not start to gain popularity in the United States until the 1990’s, when energy prices rose dramatically. While the earlier models did a decent job of heating water at a lower price and with less of an impact on the environment, they were not nearly as technologically sophisticated as are today’s models.

Tankless water heaters can handle the demands of an entire home and also have several applications for commercial use. The technology varies among different models, but the way they work is pretty much the same, and it is very easy to understand.

  • A flow sensor detects when you turn on a hot water faucet and activates the tankless water heater.
  • A series of heating elements heat the water, and continue to do so until the sensor recognizes that the flow of water has been stopped by the faucet being turned off.

There you have it. That is basically how all tankless water heaters work. Unlike a tank-style system, a tankless heater does not have to cycle on and off all day. This can result in a significant reduction in energy costs associated with heating water some models can slice those costs in half. While a traditional system overheats water to ensure that the hot water supply does not run out, a tankless system does not need to do so. It can run continually without running out of hot water. In addition, because a tankless system is not as susceptible to the mineral and sediment build-up commonly found in tank-style systems, they can last twice as long. They are usually about the size of a briefcase so they free up space that can be used for storage, and their warranties are typically much longer as well.

Once again, even though all tankless water heaters operate on the concept covered above, they come in a wide range of models and a wide range of technologies as well. They range from basic models to others that provide automatic thermostatic control. And with the range of technologies available, there are also variations in performance.
