5 Benefits of Installing a Tankless Water Heater

You’re probably researching the benefits of installing a tankless water heater for one of two reasons. The first (and less likely) reason: you’re building a new home and looking a water heater options. The second possible reason is the more likely scenario…your hot water tank just died. You have cleaned up the water that flooded the area and now you are trying to figure out what to do next.

Either of these reasons is fine. We know that heating water for your home is an overall dull topic and you have better things to do than sit at your computer researching what type of water heater is best for your family’s needs.

As you may have just unfortunately learned, a dead water heater causes quite an inconvenience in your household. Without hot water you can’t shower, wash up the dirty dishes, do laundry, or properly wash your hands. Hot water is vital to keeping your home (and the people in it) fresh and clean.

When it’s time to replace that water heater, you probably need to make a quick decision, hire a  plumber, and get the job done. You’re doing just the right thing by taking out a little bit of time to research the possibility of these units. There’s literally no time like water tank replacement time to take advantage of upgrading to this technology.

Listed below are five of the top benefits of installing a tankless water heater in your home.


If you were scenario #2, the homeowner whose hot water tank just flooded, this may be a consideration at the top of your mind! There is no tank. Ergo, the name tankless. This means that there are no more floods to mop up when your unit ages out.

This reason is usually good enough for a homeowner who just faced this situation.


Because the unit is tankless, it operates by heating the hot water “on demand.”

When you turn on the hot water tap, the heater fires up and heats the water as it passes though the lines and over the heat source. You can use hot water as much as you like and not need to wait for water to reheat.

On the other hand, a hot water tank has a certain number of gallons of hot water available. Once the tank is emptied, you wait for water to heat again.

This benefit makes these units very popular with larger families or people who use a lot of hot water for any reason.


They are hands-down more energy efficient than a hot water tank.

A traditional hot water tank has a thermostat set to a certain temperature. It keeps water heated to that pre-set temperature at all times, day and night. Therefore, when you are at work, the kids are at school, or your family is on vacation, the hot water tank is at work. It’s heating water that you don’t even need. This means that your hot water tank is wasting energy (and money)!

Because the tankless water works “on-demand,” as explained earlier, it is the more energy efficient choice.


They deliver hot water quickly. In many cases, this is faster than the time it takes for you to get hot water from the hot water tank. Of course, this varies depending on where its is located in relation to the water source. Either way,  it’s fair to say that it delivers hot water just as fast..and most often quicker…than your tank-style water heater.

Some homeowners express concern about this when making the switch over to tankless. Rest assured, your hot water is coming up quickly!


They boast an expected life cycle of 15 to 20 years. This is about double that of a tank-style water heater’s lifespan of 7 to 10 years. This makes you have a longer period of time between needing to replace your hot water heating system. That’s a convenience worth a second look!

In summary, my professional opinion is that these are worth the upgrade. Having installed both tankless water heaters and hot water tanks, I have chosen to put a tankless water heater in my own home. I find that these 5 benefits give me the best water heating solution for me.
