Tankless Water Heaters: Pros and Cons

By now, you’ve probably heard of tankless water heaters, but you may not know much about them.  Are they the right choice for your family?  We’ll break down the pros and cons and help you make an informed decision.


First off, what is a tankless water heater?  Also known as a “point of use” or “on-demand” water heater, the tankless water heater generates heat to warm water only while the tap is running.  This means that the heater does not constantly use energy to warm water, as a conventional water heater does.  It also means that the amount of hot water the tankless heater generates is not limited by tank size.


 As a result, there are two primary pros to owning a tankless water heater.  The first is that your water will be hot, nearly instantaneously, whenever you want it.  For those of you with big families lining up for the shower each morning, you can guess how wonderful that might be.  The second pro is that tankless water heaters, as a result of heating only when you need water, average 24-34% greater energy efficiency than conventional heaters.  That means less money out of your pocket when the energy bill comes, and that’s never a bad thing.  Using less energy helps the environment, too.



However, there are some cons to going tankless.  Tankless water heaters do cost more up-front than conventional heaters.  Depending on the model and the circumstances, this cost can be offset with the energy savings mentioned above.  Additionally, tankless water heaters may require more frequent cleaning than conventional models.  But at most, this cleanup is once a year, and typically consists of nothing more than flushing a vinegar solution through the system to address any scale buildup.


Overall, the pros and cons affect each family differently.  Depending on how much water your family uses, your concern for the environment, and how great your desire for near-instant hot water is, going tankless might be the right choice for you.
