Choosing Between a Traditional and a Tankless Water Heater

If you need a new water heater, you will be confronted with making a difficult decision between buying a traditional model or a tankless one. To make it easier for you to make up your mind, we have broken down the pros and cons of both traditional and tankless water heaters, thus facilitating your choice.

Pros and cons of traditional water heaters

General presentation:

  • Traditional models store and preheat the water that is in the tank.
  • Generally, the capacity of their tanks ranges from 30 gallons to 50 gallons.
  • The preheated water that they store is used when certain tasks are performed, like doing the laundry, taking a shower, or washing the dishes.
  • When the tank is empty, it refills with water and heats it up again.

The pros that come with using a traditional water heater are the fact that it is generally affordable when it comes to maintenance, and it doesn’t cost much to replace it either. On the other hand, the list of cons is pretty high, some of its biggest flaws including:

  • Short lifespan, generally up to 15 years.
  • Their big size makes them harder and more inconvenient to replace.
  • Operation adds considerable costs to the utility bill.

Pros and cons of tankless water heaters

When it comes to the best tankless hot water heater, there are a lot of advantages that you can benefit from. Here are some of the most important benefits to reap with this acquisition:

  • It delivers hot water on demand, providing as much as 2-3 gallons of hot water per minute.
  • It saves a lot of money in the long run, being about 34% more energy efficient than a traditional model.
  • The compact size and design ensure that you will be able to place the appliance wherever you want.
  • It boasts an incredibly long lifespan, most models being able to resist for up to 20 years of use.

When it comes to their downside, tankless models come with only one con, more precisely the fact that they have a higher initial cost. However, it is safe to say that the flaw is attained by the low power consumption, so you actually end up saving money when you draw the line and add up costs.

So…What’s the right pick?

After weighing the pros and the cons of both traditional and tankless water heaters, it’s clear that the best choice is to go with a tankless model. It is the more Eco and pocket-friendly option, which means that it helps save money while making you an active participant in saving the environment as well. The convenience in installation and parts replacement is another reason why it trumps traditional heaters. However, it’s the hot water on demand function that makes it the clear winner in this fight, providing convenience to its fullest.
