What Are Tankless Water Heaters?

As the name implies, tankless water systems do not rely on a tank to hold the hot water that they supply when you turn on a hot water faucet somewhere in your home. Instead, they heat the water as it flows through an advanced heat exchanger, providing a number of important benefits.

Benefits of Tankless Water Heater Systems

Tankless water heaters provide a number of benefits, including:

  • Convenience. An endless supply of hot water is the primary benefit to most homeowners. The system can produce hot water almost indefinitely. Meaning, no more cold showers.
  • Reduced risk of leaking or flooding. Because there’s no storage tank, a tankless system is much less likely to leak or cause a flood.
  • Energy savings. By heating water only when you need it, a tankless water heater will cut energy costs by 30 to 50%. A conventional system, after all, has to heat and constantly reheat the 50 (or more) gallons of water in the tank to maintain that reserve of hot water we all expect when we turn on the tap.
  • Space savings. About the size of a valise or small suitcase, a tankless water system takes up much less space than a water system with a tank. It is mounted on a wall, also saving floor space.
  • Extended life. Tankless water systems typically last up to 20 years, more than double the life expectancy of a traditional water heater.
  • Fresh, clean water. Water from a tankless system comes directly from your water system, rather than sitting in a storage tank, where bacteria and other harmful organisms might grow.
  • Improved performance. In addition to overall energy savings, a tankless system uses energy more efficiently, converting up to 97 percent of the fuel it consumes into heat for your water.
  • Reduced environmental impact. In addition to reducing water and energy consumption, a tankless system produces fewer emissions. And it will last as long as ten years longer than a traditional system, reducing end-of-service-life disposal costs.
  • Tax benefits. Tankless water systems usually qualify for federal tax credits and may also be included in state tax benefit programs.
