Understanding the difference between tank and tankless water heaters when you’re in the market for a new water heater replacement is essential. As with most things, there are advantages and disadvantages to everything. Keep in mind that water heaters are no different. Is there a perfect water heater product that is a universal must for everyone? No. Every household has their own needs, which will impact which water heater model is best for you. Let your Five Star Cincinnati Plumbing experts help you figure out what those needs are and show you both the pros and cons of each water heater type.  

Tank Water Heaters  

Tank water heaters, which are also known as storage tank water heaters, are the most common type of water heater found in residential homes. A tank water heater is an insulated tank that holds, heats and stores the hot water until it is needed. Tank water heaters generally use either electricity or natural gas as their power source. Usually, they range from 30 to 75+ gallon size tanks for residential use.  

The Benefits of Tank Water Heaters:  

  • Easier and quicker installation process: Tank water heaters are simpler to install, making it more affordable in terms of upfront cost.  
  • Stores large amounts of hot water: Tank water heaters also have a large amount of hot water ready-to-use as needed due to the tank’s ability to heat and hold hot water.  
  • Minimal maintenance requirements: With a tank water heater, you can easily keep up with its maintenance by simply staying up to date with a regular flushing regimen. As a bonus, this particular task can either be done yourself or by a plumbing professional.  
  • Lifespan: With proper maintenance, a tank water heater can last up to 8 to 10 years.  

The Energy Efficiency of Tank Water Heaters:  

Some storage tank water heaters are designed so well and insulated so effectively that they can really cut down on standby heat loss, which means you can save on your monthly energy bills!  

The Price of Tank Water Heaters:  

It’s important to think about all the costs involved with tank water heaters! 

  • Tank water heaters come with budget-friendly upfront costs. 
  • They also have lower maintenance expenses. 
  • Plus, their simplicity means lower repair costs! 

Tank Water Heaters Are Best for:  

Since their hot water supply is limited to the size of the tank, these water heaters are a great fit for small to medium-sized families!  

Tankless Water Heaters  

Tankless water heaters, also known as on-demand water heaters, are pretty fantastic! They feature highly efficient burners that quickly heat water whenever you need it, delivering hot water right on demand. Plus, with a tankless water heater, you don’t have to worry about storing water. They typically run on either electric or gas, making them a convenient choice for your home! 

The Benefits of Tankless Water Heaters:  

  • Endless hot water: With a tankless water heater, you can say goodbye to the worry of “running out of hot water!” That’s why they’re called “on-demand” water heaters. Unlike traditional models that store a set amount of hot water, leaving you waiting for the tank to refill, tankless systems provide continuous hot water as long as there’s fuel or power to keep them running.  
  • Space-saving design: Tankless water heaters are a great choice for smaller homes since they’re usually installed on walls instead of taking up valuable floor space.  
  • A longer lifespan: Did you know tankless water heaters can last up to 15 years? Of course, this depends on your home’s water type, your usage, and how well you maintain them. In contrast, traditional heaters typically last around 8-10 years. By choosing a tankless unit, you won’t have to replace it as often, which can save you money in the long run! 

The Energy Efficiency of Tankless Water Heaters:  

According to energy.gov, if you’ve got a busy household that uses a lot of hot water, tankless water heaters could save you up to 34% on energy bills compared to traditional storage tank heaters!  

Plus, while the initial cost might be a bit higher, the energy savings you’ll enjoy each month will definitely make it worth it in the long run. So, if you’re looking for a more efficient way to heat your water, a tankless option might just be the way to go! 

The Price of Tankless Water Heaters:   

It’s super important to think about all the costs involved with tankless water heaters! One thing to note is while they do admittedly have higher upfront costs, you’ll enjoy better monthly savings thanks to their energy efficiency! 

Tankless Water Heaters are Best for:  

  • With their endless supply of on-demand hot water, these water heaters are perfect for larger homes and big families!  
  • They’re also a great choice for homes with a hot tub or soaking tub.
