Advantages of Tankless Water Heaters


When it is time to replace your hot water heater, one option is to do away with the tank altogether by installing a tankless water heater. These newer, more sophisticated water heaters have less heat loss, making them more efficient. There are several other reasons why you should consider getting this type of water heater.

Fewer Greenhouse Gases

One advantage of electric water heaters is that these models do not produce any greenhouse gases. Even gas powered tankless water heaters produce fewer greenhouse gases than water heaters with tanks since the water does not have to be heated continuously. In short, tankless water heaters are better for the environment.

Endless Hot Water

Unlike with a traditional water heater, tankless water heaters never run out of water. Conventional water heaters come with a tank that eventually runs out of hot water and must regenerate before you are able to continue using it.

Having endless hot water is useful when you have a large family that quickly uses all the hot water while showering. However, with some tankless water heaters, if you will be using the heater for multiple appliances, then you will still need to stagger your water usage.

Faster Hot Water

Many people erroneously believe that tankless water heaters can deliver hot water instantly. However, water heaters cannot deliver instant hot water. The heater does provide hot water on demand by detecting when you have turned the hot water knob. However, the tankless water heater does not cause the hot water to move any faster through your pipes.

The closer the water heater is to your fixture, the faster you will receive hot water. However, after waiting a short while for your water to warm up, you will have hot water for as long as you need it.

If you do want immediate hot water, then consider installing a hot water recirculation system. The hot water travels on a loop through your home even when you do not need hot water. Therefore, hot water will always be available to any fixture.

A Long Lifespan

Another advantage of a tankless water heater is the lifespan of the equipment. These water heaters last about a decade longer than a conventional water heater, this could be because there is no tank that can become ruptured and cause flooding. Tankless water heaters usually last for about 20 years.

Less Bulky

In some homes, a tankless hot water heater is the best option because it takes up less space. The smallest units can be installed underneath cabinets or in a closet that is close to the point of use. With an antifreeze kit, the water heater can be installed outdoors.

Better at Handling Hard Minerals

Conventional water heaters do not handle minerals as well as a tankless water heater. In a tank, hot water scale forms over time. The scale coats the internal components and makes the water heater less efficient. Hard water also causes leaks and a loss of efficiency over time. Because the hot water is not stored, the tankless water heater can handle hard minerals much better.

One of the downsides of a tankless water heater is that it sometimes costs more to install than a conventional water heater. However, over the long lifespan of a tankless water heater, you will save more money through energy savings, which will eventually recoup the cost of installation. There are also some tankless versions that are easier to install.
