The Different Types of Water Heaters: Tank vs. Tankless

There are quite a few factors to consider when deciding between a tank or tankless water heater; these factors are ease of installation, energy savings, lifespan, water usage, and more.  

Understanding the distinction between tank and tankless water heaters is crucial when considering a replacement. Like many products, both options come with their own set of advantages and disadvantages. There is no universally perfect water heater; each household has unique needs that will determine the best model for them. Allow your experts at Centerville Plumbing & Drain to assist you in identifying those needs and discuss the pros and cons of each water heater type. 

What You Need to Know About Tank Water Heaters  

Tank water heaters, often referred to as storage tank water heaters, are the most prevalent type found in residential properties. These units consist of an insulated tank that holds, heats, and stores hot water until required. Typically, tank water heaters operate on either electricity or natural gas as their energy source, with sizes ranging from 30 to over 75 gallons for residential applications.  

What Are the Advantages of Tank Water Heaters?  

  • Streamlined installation process: Tank water heaters offer a simpler installation, resulting in lower upfront costs.  
  • Ample hot water storage: These heaters provide a significant supply of hot water, thanks to their design that heats and retains water effectively.  
  • Minimal maintenance requirements: Maintaining a tank water heater is straightforward, as it primarily involves adhering to a regular flushing schedule, which can be performed independently or by a plumbing professional.  
  • Longevity: With appropriate maintenance, a tank water heater can have a lifespan of 8 to 10 years. 

Are Tank Water Heaters Energy-Efficient?  

Certain storage tank water heaters are designed with exceptional insulation, effectively lowering standby heat loss and consequently reducing your overall monthly energy expenses. This underscores the importance of selecting the most suitable water heater for your home. 

How Much Do Tankless Water Heaters Cost?  

When evaluating tank water heaters, it’s crucial to consider all associated costs. 

  • Tank water heaters typically feature lower initial costs. 
  • They require less maintenance, resulting in reduced ongoing expenses. 
  • Their straightforward design leads to lower repair costs. 

Tank Water Heaters Are Best for:  

Due to the limited supply of hot water based on the capacity of the water heater’s tank, these units are most suitable for small to medium-sized families.  

What You Need to Know About Tankless Water Heaters  

Tankless water heaters, also referred to as on-demand water heaters, consist of highly efficient burners that quickly heat water as needed, providing it on demand. With a tankless water heater, there is no requirement for storage. Typically, these units are powered by either electricity or gas. 

What Are the Advantages of Tankless Water Heaters?  

  • Continuous supply of hot water: A tankless water heater eliminates concerns about “running out of hot water,” earning the label “on-demand” water heaters. Unlike traditional models, which store a limited amount of hot water and require time to refill and heat once depleted, tankless systems provide a continuous flow of hot water if there is sufficient fuel or power for operation. 
  • Space-efficient design: Tankless water heaters are typically wall-mounted, freeing up valuable floor space. This design advantage is particularly beneficial for smaller homes where space is at a premium. 
  • Extended lifespan: Tankless water heaters can last up to 15 years, depending on the water quality, usage, and maintenance practices. In contrast, traditional water heaters generally have a lifespan of around 8-10 years. By opting for a tankless water heater, you can reduce the frequency of replacements, ultimately resulting in cost savings over time. 

Are Tankless Water Heaters Energy-Efficient? 

Per energy.gov, homes that are equipped with tankless water heaters can achieve energy savings of up to 34% compared to traditional storage tank heaters. For households that consume a significant amount of hot water daily, a tankless water heater may be the optimal choice.  

Additionally, it is important to consider that despite the higher initial costs associated with tankless systems, their energy-efficient benefits will lead to substantial monthly savings over time. 

How Much Do Tankless Water Heaters Cost? 

It is essential to consider all costs associated with tankless water heaters. 

  • Tankless water heaters often come with higher initial costs. 
  • However, they provide improved monthly savings due to their energy efficiency. 

Ideal Applications for Tankless Water Heaters: 

  • Given their continuous supply of on-demand hot water, these heaters are well-suited for larger homes or families. 
  • They are also recommended for residences equipped with a hot tub or soaking tub.
