Difference Between Conventional and Tankless Water Heater

Having hot h2o at your fingertips is one of the many benefits of living in the modern age. However, that hot h2o does not just magically come with your house. It’s generated by an often forgotten, but essential, appliance–your hot hot h2o heating unit. There are two major types of hot h2o heaters: traditional models and modern tankless hot h2o heaters. Learn what the differences between the two are and which is best for you, your home, and your hot h2o needs.


A traditional hot h2o heating unit works by keeping a tank of h2o hot and ready to go. This type of hot h2o heating unit is also sometimes known as a storage hot h2o heating unit because it literally does store hot h2o for when you need it. The h2o is heated by means of a heating element powered most commonly by electricity or natural gas, but also sometimes by propane, oil, or even solar power. Although they often work very well, storage hot h2o heaters do have some downsides. If they cycle off to conserve energy, the h2o, obviously, cools down. This means that you have to then wait for the whole tank to heat back up when you need hot h2o again. Additionally, you can run out of hot h2o. Once you use all the h2o that’s in the tank, you have to wait for the tank to fill and heat up again. If you’re in the middle of your morning shower when this happens, it can be a less than pleasant experience.


The main alternative to a storage model can be found in the range of modern tankless hot h2o heaters available today. As the name implies, these units do not have a tank. Instead, the heating element is positioned so that it heats the h2o that you need as you use it. You don’t have to keep a whole tank of h2o hot (or pay for the energy it takes to do so), and you’ll never run out of hot h2o because it’s provided more or less instantaneously. Most new homes are being outfitted with this type of heating unit because it is more energy efficient and convenient than a traditional model. This does not mean, however, than you need to run out and purchase a tankless model right away if you still have a storage-style heating unit. If your traditional hot h2o heating unit is still working for you, go ahead and weigh your energy savings against the cost of buying and installing a new model. It may be in your best interest to wait until you truly need to install a new unit before you make the switch to tankless.
