When it comes to household appliances, tankless water heaters are getting more and more popular but maybe you don’t know what the hype is all about. What’s the difference from the good old water heater you’ve got now? Is it really that much better? Here is an explanation of tankless water heaters and the reasons you may want to consider getting one for your own home.
What is a tankless water heater?
Most often powered by gas, a tankless water heater uses a heat exchanger to warm your water only as it’s needed. Instead of heating an entire tank of water and holding it for use, a tankless water heater senses the demand for water and begins heating it at as it passes through the heat exchanger. Actions like turning on a faucet or a shower trigger the heater to go to work.
How is this different than my regular water heater?
A traditional water heater holds a limited supply of hot water in its storage tank. That’s why it’s not uncommon to run out of hot water, especially when doing multiple tasks. A tankless system provides an endless supply of hot water, and you can demand as much as you want all at once. You can do laundry, run the dishwasher, and take a shower all at the same time without concern.
Does this save energy?
When water flow stops, the tankless water heater shuts down. This means less energy is being used, and there is no standby heat loss. This is the heat lost and energy wasted when water is heated and stored in a tank as with traditional water heaters. Studies show that a tankless water heater can save you up to 40% on your energy bill.
So why should I get one?
Here are the top reasons to consider getting a tankless water heater for your home:
- Save money – As stated above, tankless water heaters save on your energy bill.
- Continuous hot water – Instead of having a storage tank of hot water that can be depleted, you have endless hot water at a consistent temperature. And it’s available for numerous simultaneous tasks without running out.
- Longer lasting – Tankless water heaters can be expected to last up to 20 years, which is twice as long as traditional units.
- Save space – Traditional water heaters may take up to 16 square feet of space in your home, while tankless units are a fraction of the size and can be installed on any wall outside or inside your home.
- Green – Many tankless water heaters are approved by ENERGY STAR® to meet the strict energy efficiency guidelines laid out by the U.S Environmental Protection Agency and the Department of Energy.
