Traditional water heaters work by filling up the tank with water and keeping it heated constantly. When the hot water supply is exhausted it refills itself, heats back up, and then maintains the temperature it’s set at. While there are many energy efficient models available, and ways to improve your water heater’s efficiency such as wrapping it, energy is still used twenty-four hours a day to keep the water heated, whether it’s being used or not.
A tankless water heater supplies hot water on demand. When needed, water is pumped through the tank and heated for use, and when there is no demand for it, shuts itself off. This will save energy and money throughout the year.
Another advantage is longevity. An average conventional water heater lasts for about 7 to 10 years, while a tankless model can last up to 20 years. A tankless heater is smaller than a regular water heater, making it ideal for homes with less storage space.
These money and space-saving water heaters come with either an electric or gas ignition, and are available in different sizes to accommodate your needs. Another option is to have a dedicated tankless system for specific appliances, such as a washing machine, that use the bulk of your hot water supply.
Replacement parts for tankless heaters are inexpensive, and the heaters themselves require little maintenance. Although the initial cost may be greater, you will save in the long run with lower utility bills and less frequent replacement costs.
