Tankless vs Tank Water Heater: Which Is Better?

tankless vs tank water heater


When it comes to home water heaters, there are two main types: traditional tank heaters and tankless heaters. Both have their pros and cons, and the type that is right for you will depend on your unique needs and preferences. 


What Is A Tankless Water Heater?

A tankless water heater is as the name implies, a type of water heater that does not have a tank. Tankless water heaters heat water on demand, meaning they only heat water when you need it. This differentiates them from traditional tank water heaters, which heat and store large amounts of water even when you don’t need it. 


Tankless water heaters can be gas or electric. Gas are typically less expensive to run, but may be slightly less efficient than electric tankless water heaters. 


What Is A Tank Water Heater?

A tank water heater is the more traditional type of water heater that stores hot water in a tank. The tank is usually made of steel or stainless steel, and it is insulated to help keep the water hot. Tank water heaters typically have a capacity of 30-50 gallons, but larger models are available. 


Tank water heaters work by heating water and then storing it in the tank until it is needed. Most tank water heaters have two heating elements, one at the bottom of the tank and one near the top. The bottom element is used to heat the water, and the top element is used to maintain the temperature of the water. This type of water heater is powered by electricity, propane, or natural gas.


Tankless Water Heater vs Tank: Pros and Cons


Tankless Water Heater Pros:


  • Tankless water heaters are much more energy efficient than traditional tank water heaters. As we mentioned previously, a tankless water heater only heats water as you need it, rather than constantly having to reheat a tank of stored water. So there is no wasted energy. 


  • Tankless water heaters tend to have a longer lifespan since they don’t have to work as hard to maintain a consistent temperature and they don’t corrode. A tankless water heater can typically last for 15 to 20 years. 


  • Provides a consistent flow of hot water because you don’t have to wait for a tank to fill up and heat. 


  • Takes up less space since it doesn’t have a tank. 


Tankless Water Heater Cons:


  • Tankless water heaters have more expensive upfront costs for purchasing and installation than traditional water heaters that have a tank. Tankless water heater installation can be more complex than traditional tank installation, so it’s important to hire a qualified professional for the job.


  • You also might need to install additional gas lines or electrical circuits to support a tankless water heater.


Tank Water Heater Pros:


  • Usually less expensive upfront than a tankless water heater.


  • Available in a variety of sizes.


Tank Water Heater Cons:


  • Typically has a shorter lifespan of about 10 years. 


  • Tank water heaters are less efficient than tankless water heaters, because they use energy to keep the water hot even when you’re not using it. So overall they require more energy to operate. 


  • Takes up more space than a tankless water heater. 


  • May require more maintenance than a tankless water heater, as tanks can be prone to corrosion and leaks. 


  • Tank water heaters have a limited supply of hot water, so if you have a high demand for hot water, you may need to invest in a larger tank. 

Is Tankless Water Heater Better Than Tank?


While both traditional and tankless water heaters will get the job done, if you’re questioning which one is a better long-term investment, we believe the answer is a tankless water heater.


While a tankless water heater is more expensive upfront, the fact that it is more energy efficient and has a longer lifespan means that the money you’ll save on your energy bill and lack of maintenance costs will more than make up for it. 


So if you’re looking for a more efficient and space-saving option, a tankless water heater is the way to go.
