How to Choose Between Tank vs. Tankless Water Heaters

There are many types of water heaters available on the market today. Conventional, or tank water heaters, hold all of your hot water in a tank. The system works hard to keep this water hot so it is available whenever you need it.


Tankless water heaters are newer and they don’t store water. Instead, they heat the water as it is needed. This can save energy and money because the system isn’t constantly heating water. However, these water heaters cost more to install and may not be the best option for some homes.

The Pros and Cons of a Tank Water Heater

A tank water heater costs less to install upfront and it is a simpler system, so repairs are less complex and generally less expensive. 


However, there are several downsides to a tank hot water heater. They cost more to use because they are constantly heating water to whatever temperature you have set the system to. They also take up a lot more space in your home and they don’t last as long as the tankless versions.


Most tank water heaters only have enough hot water for about three showers. If you need more hot water than that, you will either have to wait or make do with cold water instead!

The Pros and Cons of a Tankless Water Heater

Tankless water heaters last 20-30 years, which is twice the average lifespan of a conventional water heater. They can also reduce energy costs by up to 25%, so they cost less to operate and can pay for themselves over time. They don’t take up nearly as much space as a conventional water heater does and you’ll always have plenty of hot water, whenever you need it.


On the other hand, tankless water heaters can cost up to 5 times more than conventional water heaters cost. Some of them can fail to produce enough hot water, especially if you’re using a lot across several systems at once (like taking a shower while someone washes dishes and you’re running your washing machine). Replacing a conventional water heater with a tankless system can also be expensive because existing piping must be relocated.
