Benefits and Disadvantages of Tankless Water Heaters

Sooner or later, you will have to replace your hot water heater. When that time comes, you may consider replacing it with a tankless hot water heater. Tankless hot water heaters are a popular option for home-owners, but there are both benefits and disadvantages to selecting a tankless model versus a traditional water heater.

Benefits:

  • They provide an unlimited supply of hot water when you want it. As their name indicates, tankless hot water heaters do not use a tank. This means that there is no need to fill a tank and then slowly heat it before you have hot water. Instead, the water is heated as soon as you demand it and for as long as you need it. That means you can shower for as long as you want to without ending with an unpleasantly cold finish.
  • They are energy-efficient. Because they do not use energy keeping water hot even when it is not needed, tankless hot water heaters save energy.
  • They have a longer life-expectancy than tank systems. The typical life-expectancy of a tankless hot water heater is 20 years—about 50 – 100 percent longer than tank systems.
  • They offer many features and options. Some models include features such as digital displays, self-diagnostic programs, and/or remote controls that allow you to adjust the temperature.

Disadvantages:

  • Potentially inconsistent water temperature. If you select a model without self-modulating temperature control, you may experience fluctuations in water temperature depending upon how much water you are using.
  • Potentially insufficient hot water. Tankless water heaters heat water as you need it. However, they can only heat a certain volume at a time. If you get a system that too small, you may find that it cannot handle simultaneous demands, such as providing enough hot water for two showers or a shower and a washing machine.
  • Depending upon your electricity provider, your energy-efficiency may get expensive. Whereas tank systems consume a fairly steady supply of electricity, tankless systems draw power in surges when the system is called upon to heat water. Electric companies that impose a demand charge fee may cause your electric bill to increase.

Tankless water heaters are an increasingly popular choice for homeowners. However, it is important to understand the benefits and disadvantages they offer before deciding upon the best option to meet your needs.
