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 making it easy for you to make the right choice.

Pros and cons of traditional water heaters

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, such as 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 and it doesn’t cost much to replace it. On the other hand, the list of cons is pretty high when it comes to such models. They have a short lifespan, generally, of up to 15 years, they are big in size and hard to replace, and they increase the utility bill considerably.

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 if you go with and the most important advantage is definitely the fact that this type of water heater actually delivers hot water on demand, providing as much as 2-3 gallons of hot water per minute. Also, 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. The long lifespan is another pro worth taking into consideration as such a unit can resist for as long as over 20 years. When it comes to their downside, tankless models come with only one con, more precisely the fact that they have a higher initial cost.
