Just a few years ago, tankless water heaters were rarely heard of in the U.S. Today, they have evolved into an energy saving home water heating option that more homeowners are considering. Tankless water heaters have become more popular because they save homeowners tremendous amounts of money and energy. If you need to replace your water heater, consider an energy saving tankless water heater. Tankless water heaters cost more up front than conventional tank water heaters. But in the long term, they cost less to run than conventional water heaters.
Tankless water heaters, also known as on demand water heaters, are compact units that work on gas or electricity to heat your water as needed. If you use an on-demand water heater, you'll never run out of hot water. With a tankless water heater, you will never have to wait again for your water tank to fill up with enough hot water for you to shower and run the dishwasher at the same time.
Unlike conventional tank water heaters, tankless water heaters heat just the water you need. Conventional heaters continuously heat your water, which is a huge waste of energy. Tankless water heaters are one of the best ways to conserve energy in your home.
When using a conventional water heater tank, you are paying to heat your water 24 hours a day, 7 days a week. Tankless water heaters only heat water on demand. They can reduce your energy consumption and energy costs by up to 50%.
Gas vs. Electric
Tankless water heaters are powered by either gas or electricity. Most plumbers agree that natural gas-fired heaters are more cost efficient, as they provide higher flow rates than electric heaters.
Types of Tankless Water Heaters
There are three types of tankless water heater applications: single point application, multi point application and whole house application. The single point is used just for one fixture, such as a kitchen sink. The multi point is used in a room where more than one application is needed, such as in a bathroom (sink and shower). The whole-house application is used when a single heater heats the water for the entire house. Gas heaters are the best for a whole house application. Make sure to check with your plumber to ensure that you have the proper gas setup and or electrical capacity for the tankless heater that you choose.
Consider Your Location
Location matters in determining if you will benefit from a tankless water heater. It will also determine the flow rate you will need in your heater. The colder your climate, the colder the incoming water will be, and the greater the rise in temperature will be to heat the water. If you live in a colder state, such as Illinois, you should consider how much you will save by installing a tankless water heater.
