Sra Its Time To Replace Your Water Heater

It’s Time to Replace Your Water Heater: Which is Better, Tankless or Traditional?

If you just began your search for new water, there are a couple of different types to consider for your decision. This will be an investment in your home for many years. Here we will share with you how water heaters are different and the benefits and pain points of each.

The Differences Between A Tankless And A Traditional Water Heater

Tankless and traditional water heaters have key differences in features and functionality. Understanding how each type works will let you choose which is best for your home and receive the best water temperature.

The Basics

Traditional water heaters come equipped with a water tank that stores water. This tank will preheat 30-50 gallons of water. Once that hot water runs out, it will begin refilling and preheating 30-50 more gallons of water.


Tankless water heaters don’t have a tank and don’t store water. Instead of this method, they will use gas or electricity to heat up the water as needed. This only heats the water that is being used and is on an “on-demand” system.

And as with anything, there are pros and cons to each type of water heater.


Tankless Water Heaters: Pros and Cons



  • Higher Energy Efficiency. When compared to traditional water heaters, these types of heaters are 24%-34% more energy-efficient as long as up to 41 gallons of water is used per day.
  • Lower Energy Bills.Because tankless heaters only heat up the amount of water you are using, they are more energy efficient. If you live in an area where energy costs more, you may be able to save on your energy bill with a tankless heater.
  • Saves Space.Since these don’t have large, bulky tanks they can fit into smaller places. This makes a great option if you are trying to maximize space in your home.
  • On-Demand Hot Water. Since only the water you’re using is heated, your water will continue to run hot until you are finished with your task.



  • Electricity Dependent. These units require electricity to heat the water, even if the unit is a gas-powered unit. So if a power outage occurs you won’t be able to have hot water. If you live in an area that experiences a lot of outages this may not be the best option for you.
  • Unit Cost & Upfront Cost. Upfront cost of tankless heaters is more than traditional water heaters. This is because the unit costs more and the installation is a little more complex. Although the upfront cost is higher, since these units are more energy efficient and have a longer lifespan, they should pay for themselves in a few short years.
  • Less Efficient at Multiple Appliances.Because only a limited amount of hot water is heated at a time, if you’re running more than one water appliance such as your dishwasher or washing machine at the same time your hot will go in and out. This may be avoided if less water is used or an additional water heater is installed.

Traditional Water Heaters: Pros and Cons


  • Installation Cost.Due to homes already having the appropriate plumbing necessary for the installation of these water heaters, the cost is nearly half that of a tankless water heater.
  • Easy Replacement.Because these water heaters are more common, it’s easier for plumbers to replace and maintain them.
  • Increased Hot Water Flow. Since these water heaters come with a large water storage tank, they will have hot water ready for when you need it. It also remains hot when flowing to multiple appliances at the same time.


  • Take Up A Lot of Space.These heaters must be in a covered area and are very bulky due to the storage tank so they take up a lot of space. This may not be ideal if your home is smaller.
  • Uses More Energy. Because the water heater is always reheating water to the pre-set thermostat setting, it will still be using energy even if you’re not actively using the hot water.
  • Relatively Short Lifespan. The service life of traditional water heaters is much shorter than a tankless heater. They tend to last 10-15 years on average.

Even though there are pros and cons to each type of water heater, it really depends on your needs for your home. Keep in mind these points when you’re deciding between a traditional and tankless water heater.
