10 Benefits of Tankless Water Heaters

Are you thinking about upgrading or replacing your traditional water heater? A tankless water heater might be the perfect solution. Known for their efficiency and reliability, tankless units are becoming increasingly popular among homeowners. In this guide, we will explore the top benefits of making the switch.

What Are the Benefits of Investing in a Tankless Water Heater?

There are many benefits to installing a new tankless water heater in your home, including:

1. Endless Warm Water

With a tankless water heater, you will never run out of hot water compared to a tank system that only holds as much water as the tank stores. A traditional tank water heater will quickly run out of hot water if you have a large family—after one or two hot showers, the next person has to wait for the water to heat again. A tankless water heater provides an endless supply of warm water to match your needs.

2. High Efficiency

The next advantage of buying a tankless water heater includes great Energy Star ratings. You can expect a tankless water heater to be about 30% more efficient than a tank water heater. This is because a tank water heater needs to constantly heat the water in the tank throughout the day in case hot water is needed. Whereas a tankless water heater only heats water when it is needed, reducing standby energy loss and overall usage.

3. Longer Lifespan and Warranty

Tankless water heaters have some of the best warranties and a remarkable lifespan. With proper installation and maintenance, a tankless water heater will provide years of energy-efficient service. Plus, they often have a life expectancy of up to 20 years, longer than most tank water heaters.

4. Compact Design

A tankless water heater means no tank. Without a bulky tank to store water, you can free up valuable space in your home or garage. These water heaters can be installed on the wall, freeing up floor space with their compact design—taking up 80% less space than a traditional tank water heater.

5. Lower Energy Bills

Tankless water heaters will save you money on energy costs because they consume a lot less energy than tank water heaters. For maximum cost-effectiveness, make sure the unit is Energy Star certified and suited to your home's requirements.

6. Less Maintenance

Tankless water heaters require maintenance just like any other water heating product to guarantee optimal performance. However, a compelling benefit that draws many homeowners to install tankless water heaters is that these systems do not need to be flushed for sediment. This makes the need for maintenance less frequent, but will ultimately depend on water hardness, temperature, and other environmental factors.

7. Improved Safety

Tankless water heaters are designed and built to provide long-lasting and safe operation. They have controls in place that monitor water temperatures, exhaust gas, and the burner to ensure proper operation. If any of these components fail, the unit will shut off to prevent overheating and other potential hazards.

8. Reduced Installation Costs

Typically, the cost of a tankless water installation is less than other water heater types because of its design and components. To get a full cost breakdown for what a tankless water heater would be in your home, call our crew at Corley and we can help.

9. No “Cold Water Sandwiches”

You can get tankless water heaters that have a buffer tank to prevent cold water sandwiches and secure continuous hot water. The "cold-water sandwich effect" occurs when cold water enters the hot water supply line during frequent on/off operations.

10. Environmentally Friendly

With better energy efficiency and lower CO2 emissions than tank water heaters, a tankless water heater will lessen the carbon footprint of your home. Many tankless water heaters can also save you hundreds of dollars on your project by qualifying for a Federal Tax Credit and/or discounts from participating state utilities.

How Do Tankless Water Heaters Work?

Tankless water heaters provide hot water only when you need it. Instead of storing water in a tank, they heat water as it flows through the unit. When you turn on a hot water tap, cold water enters the system, where an electric element or gas burner heats it instantly. This "on-demand" process ensures a continuous supply of hot water while saving energy by avoiding constant reheating.

Since tankless systems don't require a storage tank, they take up less space and are often mounted on a wall, making them a smart choice for energy-conscious homeowners.

What is the Flow Rate of a Tankless Water Heater?

Flow rate measures how much hot water a unit can provide at once, calculated in gallons per minute (GPM). Common GPM estimates include:

• Shower: 1.5 - 2.5 GPM
• Kitchen Sink: 1 - 1.5 GPM
• Dishwasher: 1 - 2 GPM
• Washing Machine: 2 - 3 GPM

Most residential tankless water heaters deliver 2 to 5 GPM. Larger homes may need a higher GPM unit to meet demand. By understanding tankless water heaters and calculating your home's flow rate, you can enjoy energy savings and reliable hot water.
