When looking for a new water heater, it’s important to understand the difference between tank and tankless models. Like most products, each type has its pros and cons. There isn’t a one-size-fits-all water heater; every household has unique needs that will determine the best model for you. Let your experts at Westerville Plumbing & Drain help you identify your needs and explain the advantages and disadvantages of each type of water heater. 

Tank Water Heaters  

Tank water heaters, also called storage tank water heaters, are the most common type found in homes. They are insulated tanks that hold, heat, and store hot water until you need it. These heaters typically run on electricity or natural gas and come in sizes ranging from 30 to over 75 gallons for residential use. 

The Benefits of Tank Water Heaters:  

  • Simple and quick installation: Tank water heaters are easier to install, making them more affordable upfront.  
  • Large hot water storage: These heaters provide a significant amount of hot water on demand because they heat and store it in the tank.  
  • Low maintenance: Keeping up with maintenance is easy with a tank water heater; just follow a regular flushing schedule. You can do it yourself or hire a plumber.  
  • Longevity: With proper care, a tank water heater can last 8 to 10 years. 

The Energy Efficiency of Tank Water Heaters:  

Some storage tank water heaters are designed with excellent insulation, which helps reduce standby heat loss and can lower your monthly energy costs. This highlights the importance of choosing the right water heater for your home. 

The Price of Tank Water Heaters:  

When evaluating tank water heaters, it’s essential to look at all associated costs. 

  • Tank water heaters have lower initial costs. 
  • They also require less maintenance. 
  • Their simplicity leads to lower repair costs. 

Tank Water Heaters Are Best for:  

These water heaters have a limited supply of hot water based on the size of their storage tank, making them ideal for small to medium-sized families.  

Tankless Water Heaters  

Tankless water heaters, or on-demand water heaters, use efficient burners to heat water as quickly as needed, delivering it right when you want it. With a tankless system, you don’t need to store water. These heaters typically run on either electricity or gas. 

The Benefits of Tankless Water Heaters:  

  • Endless hot water: With a tankless water heater, you never have to worry about running out of hot water. These “on-demand” heaters provide continuous hot water as long as there is fuel or power available. Unlike traditional water heaters, which store a limited amount of hot water and require time to refill and heat, tankless systems keep the hot water flowing. 
  • Space-saving: Tankless water heaters are typically mounted on walls, so they take up less space compared to traditional models that sit on the floor. This is especially useful for smaller homes with limited space. 
  • Longer lifespan: Tankless water heaters can last up to 15 years, depending on your water type, usage, and maintenance. In contrast, traditional water heaters usually last around 8-10 years. Choosing a tankless water heater means you won’t have to replace your unit as often, potentially saving you money over time. 
  • The Energy Efficiency of Tankless Water Heaters:  

According to energy.gov, homes with tankless water heaters can save up to 34% on energy costs compared to traditional storage tank heaters. If your household uses a lot of hot water daily, a tankless water heater could be the best choice for you.  

Additionally, keep in mind that while the initial price of a tankless water heater might be higher than that of a storage tank heater, its energy efficiency can lead to significant savings on your monthly bills over time. 

The Price of Tankless Water Heaters:   

It’s important to consider all costs associated with tankless water heaters. 

  • Tankless water heaters come with higher upfront costs. 
  • However, they offer better monthly savings due to their energy efficiency. 

Who Should Consider Tankless Water Heaters: 

  • These heaters provide an endless supply of hot water, making them great for larger homes or big families. 
  • They’re also a good choice for homes with hot tubs or soaking tubs.
