Myths About Tankless Water Heaters

The inner-workings of tankless water heaters need not be shrouded in mystery. As tankless heaters continue to rise in popularity, so do rumors and myths surrounding how they work and what advantages they provide.

So, let’s bust some of the more popular myths and find out what is true and what is not.


Myth #1: Only a Tank Can Provide a Lot of Hot Water

Sure, tanks hold a lot of hot water, but this doesn’t mean that tankless heaters will run out of hot water. In fact, they never do.  Tankless water heaters heat up instantly as water passes through the heat exchanger.  On the contrary, once standard tanks run out of their hot water supply, you get only cold showers!


Myth #2: Tankless Water Heaters Provide Instant Hot Water

This myth is partially false.  There are two types of tankless water heaters: whole-home and point-of-use.  Whole-home water heaters are typically located in garages or utility closets.  They cannot provide instant hot water simply because of the time it takes for water to travel to various outlets.  However, once the water is hot, it remains so until turned off.  Point-of-use tankless heaters do provide instant hot water, but can only support one faucet for a limited time.


Myth #3: Tankless Water Heaters Cannot Provide Continuous Hot Water

Properly sized whole-home tankless water heaters can and will provide continuous and endless hot water.  It’s that simple.


Myth #4: Tankless Water Heaters Cost More to Operate

It is true that tankless water heaters cost more up-front at installation.  However, despite their initial cost, tankless water heaters are one of the most beneficial long term investments you can make in your home.  Typically lasting five to ten years longer than standard tanks, tankless water heaters will also require far less maintenance.  Tankless heaters tend to lower monthly utility bills and increase overall home values at the time of resale.
