Advantages to Converting Your Water Heater

Discover the benefits of switching your water heater to a tankless model

Change This

Converting your water heater to a tankless model is a valuable upgrade for any home. These units last longer, use less energy and can reduce utility bills by up to 20 percent. Read on to find out how you can save hundreds of dollars with an energy-efficient tankless water heater.

Gas systems heat water using a gas burner. This can reduce energy use by up to 30 percent compared to traditional water heater tanks.

For electric systems, there are a few options. Standard tankless heaters use an electric element to heat water only as needed. Hybrid versions take the process a step further by pulling in ambient air and extracting the heat. (Hybrid water heaters also respond 33 percent faster than standard tankless units, making them a great option for any home.)

Note: In 2015, the U.S. Department of Energy updated their energy-efficiency standards. Tanks installed before 2015 should be replaced as soon as possible to meet the new requirements.

lower utility bills

Since tankless water heaters use less energy, they can also lower your utility bills. ENERGY STARĀ® estimates that the average household can save hundreds of dollars every year by converting to a tankless unit.

These water heaters can conserve almost 35 percent more energy than traditional tank models and simultaneously service every high-demand point in your home, such as the bathroom, kitchen and laundry room.

tankless water heater - extended life span

On average, tankless water heaters last five to 10 years longer than water heater tanks. With proper maintenance, a tankless water heater can offer up to 20 years of lasting use.

Households using a traditional unit can quickly run out of hot water because the home's entire supply is stored within the tank. On the other hand, the heating elements in tankless and hybrid varieties only heat water as needed, for as long as required. This on-demand design offers continuous hot water.

tankless water heaters save space

Most traditional tanks hold between 40 to 60 gallons of water and usually measure about 60 inches tall and 24 inches wide. Since tankless water heaters are much smaller, they take up far less space in your home. Their standard size is 28 inches tall by 20 inches wide and 10 inches deep.

tankless water heaters require less maintenance

Water heater tanks generally require annual maintenance, and in some regions, they need to be serviced every six months. Alternatively, tankless water heaters require very little upkeep. Depending on the quality of your water supply, they can sustain full function for four to five years without maintenance.

If you live in an area with hard water, an annual cleaning is still recommended to remove mineral buildup near the heating element. This standard maintenance is easy to perform: use a vinegar solution to flush the unit for 60 minutes and remove any lingering sediment.
