Homeowners rely heavily on hot water in their homes. From laundry to baths, hot water is in high demand, especially when multiple people live in the home. When you have a traditional water heater, you are limited to the amount of hot water in your tank. This requires waiting for the tank to fill and heat again. The cost to heat your water can be one of your largest utility expenses, which is why we recommend considering a tankless water heater.


Traditional tank water heaters continuously use energy to keep the water hot, ready for use. Tankless water heaters only expend energy when a tap or the dishwasher is turned on. These tankless systems are becoming more popular today for many reasons. To help you decide if a tankless water heater is for you, we’ve given you a list of 6 benefits below.

Less Space Requirements

The conventional storage tank water heater holds 40-60 gallons and is on-average 5 feet tall. They take up a good amount of space in your utility room, space that could be better utilized for storage or other things. A tankless water heater is approximately the size of a small suitcase, which means there’s lots of room left for other things.



When you’re selecting a tankless system, take into account the size of your home, the rate of water flow and temperature you prefer, and your household size. You want to make sure you have a large enough system to do the job correctly and you have allotted the right amount of space.

Energy and Cost Savings

When a home uses 41 gallons of hot water per day, tankless water heaters can be 24%-34% more energy efficient than traditional water heaters. For homes that use approximately 86 gallons per day, the energy savings can be up to 14% more.



Some homeowners are hesitant to invest in a tankless water heater because of the high cost. Don’t let this be the reason you pass over an on-demand system. They typically have lower operating and energy costs. This is a big offset and can save you money in the long run.

Unlimited Supply of Hot Water

When you’ve got a house full of people, whether it’s visitors for the holidays or you’re blessed with lots of kids, it can put a huge demand on your hot water resources. Between the cleanup of dishes after meals and the numerous showers that are taken each day, your tank water heater will be slowing down and the water will run cold quickly.



Each tankless water heater works by heating the water on-demand from an external source. They don’t use the water in the storage tank. These tankless heaters provide hot water near the rate of 2-5 gallons per minute. As long as there aren’t multiple showers going at the same time, the water should be hot enough for everyone.

Cleaner Water Supply

Standard water heaters can have water sitting in the tank for a long period of time. Sediment buildup and rust contaminants can seep into the water from the interior of the tank. No one wants to bathe or cook with contaminated water.



Since tankless water heaters heat on-demand, the water doesn’t sit in the tank waiting to be used. This keeps the water cleaner and safer for everyone in your home.

Lower Risk of Leaks and Water Damage

In a tank system, small leaks can happen. No matter how small they are, it most likely means there are big problems going on inside. As we just mentioned above, tankless water heaters heat on-demand. There aren’t dozens of gallons of water sitting in a metal container corroding the tank. Because of this, leaks due to corrosion don’t happen with tankless systems.

Zero Risk of Tank Exploding

Water heaters exploding can be terrifying. The main reason tank water heaters can explode is because of pressure. Sediment buildup, a gas leak, or a poor anode rod can cause excess pressure on those systems. As we mentioned above, tankless water heaters heat on-demand. With no water sitting in a metal container corroding the tank, there’s no risk of leaks.


As you can see, there are lots of advantages of upgrading to a tankless water heater.
