As you are aware that there are aces and drawbacks to both types of heaters, but to get the perfect piece of water heater for your home as per your specific needs is totally up to you.

Tank Water Heater – Introduction

Tank water heaters are the traditional water heaters that most people are familiar with. They store a set amount of hot water in a tank, which is then released when you turn on the tap. Because they store hot water, tank water heaters can take a little time to heat up new water, but they provide plenty of hot water for most households.

On the contrary, the tankless water heaters function to only heat up water as it’s needed. So if you’re taking a shower and someone else in the house turns on the faucet for a dishwasher or washing machine, the tankless heater will fire up and heat up more water very quickly to meet that demand.

Pros Of Tank Water Heaters

You only step into the physical or online market sometimes to purchase a water heater. So, there are several things to note down when getting a tank water heater.

  • Long-Lasting

Water heaters are one of the basic necessities of life. So, while getting water, it is important to get a sustainable water heater. Tankless water heaters tend to last longer. The typical lifespan of a tankless water heater is around 15 to 20 years, while a tank water heater sustains for just 10-15 years, and if you maintain them regularly, it can sustain for 5 to 10 years more.

  • Number of people living in your home
  • Everyday hot water requirement

All of these things will dictate which type of water heater is right for you.

Another factor to consider is how much hot water you use on a daily basis. If you only consume a minimum amount of hot water each day, you can get away with a tankless water heater. But if you use much hot water—for instance, if live in a multi-family home—you might need a tank water heater.


At the end of the day, a perfect water heater for your home exclusively depends on your particular requirements. If you use too much hot water, then a tank water heater is right for you. But if you don’t use much hot water or you don’t mind taking a little break between showers, a tankless water heater might be a better fit for your home.
