Traditional vs. Tankless Water Heaters: Investigating the Pros and Cons

Buying a new water heater is a significant investment, so it's essential to consider all relevant factors before making a choice. One of the most significant hurdles in the decision-making process is opting for a traditional or tankless water heater.

Some homeowners have a clear preference, but others can see the benefits of both options. Often, a list of pros and cons is the best way to reach a decision. Let's go over all the features of each option:

Advantages of traditional water heaters

For many homeowners, the lower initial cost of the traditional water heater is a powerful argument. A storage water heater makes the most sense if you're on a budget.

A traditional water heater is a prudent option for smaller households, especially if one or two people stay at home during the day.

Plus, newer traditional water heaters are more efficient than older models. Remember that a traditional water heater will require less maintenance and be generally easier to replace.

Disadvantages of traditional water heaters

The most obvious drawback of traditional water heaters is running out of hot water. A storage water heater might not be the best solution for larger households. No one likes being the last person to take a shower, as it might be lukewarm at best.

Furthermore, traditional-style water heaters are often massive, therefore, not ideal for people with smaller homes. Finally, this water heater has a shorter lifespan and will last around 10-15 years on average.

Advantages of tankless water heaters

The average traditional water heater will heat and store between 30-50 gallons of water. Now compare that to the fact that a tankless water heater produces hot water on-demand.

It becomes easy to see why so many homeowners choose to have hot water any time of day and night. A tankless water heater can be a lifesaver for bigger households during the early morning rush.

Even for those who live alone and spend their days outside of their home, effortless access to hot water can significantly improve the quality of life.

Tankless water heaters take up much less space and are more energy-efficient. Furthermore, compared to traditional water heaters, they last about five years longer.

Disadvantages of tankless water heaters

The most convincing argument against tankless water heaters is the price tag. They are more expensive upfront, which is a deterrent to many homeowners.

Still, various models at different price ranges are available on the market. Finally, it's essential to consider that tankless water heaters usually need more maintenance, and the process of retrofitting can be costly.

There is no right and wrong decision when it comes to water heaters. Households are unique, so what works for one family may not work for the other. 

Households with high demands for hot water and not enough space can benefit from a tankless water heater. However, those with more space and less need for hot water on-demand will enjoy their traditional water heater. 

When choosing a water heater, the most crucial factor is to find a high-quality unit. It's also vital to contact a reliable plumbing service for efficient installation.
