7 Ways Tankless Water Heaters Are Different From Regular Tank Based Ones

When deciding to buy a water heater for your home, you will have to choose between the tankless and the tank based types. And if you are not sure which one is suitable for your home, then this post will help you decide on that. Below, we look at seven ways tankless water heaters are different from the tank based types.


Optimal Operation

A big advantage of tankless water heaters is that they will only function when there is a demand for hot water, unlike a tank based water heater. As such, they will use less energy, helping you cut down energy expenses by up to 35%. So, if you are looking to purchase an energy efficient water heating system, a tankless water heater is the one you must buy.


A big drawback of tankless water heaters is that it can be quite expensive. In fact, you may have to shell out twice or thrice the money for buying a tankless water heater when compared to a tank based one. While the regular water heater might cost you about $800, a tankless one will cost you anywhere from $1600 or more. So, if you do not wish to spend too much money on buying a heater, then you may be better off sticking with the normal tank based water heater.

Cleaner Water

In a normal water heater, the water is stored in a tank for a long period of time until it is utilized. As such, the water can contain rust and other debris that fall into the tank. In contrast, a tankless water heater has no such issues since water is never stored in a tank. Therefore, you will always be using the cleanest water, which is free from all such contaminants.

Less Space

If your home is congested and you don’t have any space, then tankless systems are perfect for you. Since such water heaters do not require the installation of any tank, they will need only a little space. In fact, they are so compact in size that you can just mount it on the wall.

Lasts Long

When it comes to life expectancy, tankless heaters have an advantage over the tank based types. These systems are expected to last for at least 20 years. This is around 5 to 10 years longer than the life expectancy of a tank based system. Plus, tankless heaters won’t need much maintenance during the period, thereby saving you precious time and money over its lifetime.

No Flooding

With a tank based system, there is always a possibility of the tank rupturing, and the water flooding the surface. Such a possibility is completely absent in the case of tankless water heaters.

If the above comparisons make you want to buy a tankless heater, make sure that you first go through the online reviews for tankless water heaters before you buy them. This will give you a good idea of how the people who have used the product feel about it, making your buying decision much easier.
