7 Advantages of Tankless Water Heaters Versus Conventional Tank Style

Tankless water heaters are steadily growing in popularity among green-conscious consumers. When you consider all the advantages of a tankless versus conventional water heater, it’s no wonder why. It’s estimated that nearly 75 percent of tank water heaters that fail either burst or leak between 30 and 80 gallons of rusty, unsanitary water. There are several reasons why it’s a good idea to switch your water supply from a tank to a tankless water system, this page outlines a few of those pros and cons.

Operational Energy Savings

1. Energy-conscious consumers will appreciate the substantial energy and operational savings in the long run when they choose a tankless versus conventional water heater. One reason people sometimes give for choosing a tank versus tankless hot water system is the lower installation cost, sometimes half, than that of a tankless system. Although you’ll initially spend more dollars up-front to purchase and install a tankless system, you’ll begin to see significant savings down the road. This is because tankless heaters provide only the hot water you need at a specific moment in time.

On Demand Convenience

2. Thus, another advantage of tankless water heaters is the convenience. Simply at your command, you can get between 2 and 3 gallons of hot water per minute. You never need to worry about waiting for the water to heat before it’s warm enough to use. You won’t run out of hot water like you might with a tank. Anyone who’s lived in an apartment with a less-than-sufficient tank heater knows about the need to scramble to the shower early before all the hot water is gone!

No Heat Loss

3. A disadvantage of a tank versus tankless hot water heater is that you’re wasting money on hot water that’s just standing idly and waiting for someone to use it. In addition, even an insulated tank loses heat and needs to be continuously reheated. According to the Energy.gov website, a household that uses “41 gallons or less of hot water daily” can realize between “21 and 34 percent” greater energy efficiency by choosing a tankless versus conventional water heater. Large families who use more hot water will enjoy even greater energy savings.

Compact

4. One more advantage of tankless water heaters is they’re small and don’t require a lot of space. A conventional 50-gallon tank can be up to 5 feet tall and 2 feet wide. In contrast, a tankless heater is only about the size of a large computer! If you live in an apartment or small house, a tankless water system definitely saves you valuable space!

Indoor or Outdoor Installation

5. You can even install a tankless heater on an outside wall, which is one more advantage of a tankless water system.

Extended Warranty Period

6. Because tankless water heaters are relatively new technology, they usually come with a 15-year warranty and can last as long as 20 years. Most tanks come with only a 6-year warranty and need to be replaced after 10 to 12 years, mostly due to mineral build-up.

Low Maintenance

7. One more cost-saving advantage of tankless heaters is they typically require little maintenance.

Other Ways to Go Green at the Same Time

There are other steps that can go hand-in-hand with installing a tankless water heater to save even more energy. Leaky faucets and shower heads waste a significant amount of hot water, and either you or a plumber can easily replace them.

Low-flow fixtures, such as shower heads and faucets, also help cut down on unnecessary water use by as much as 25 to 60 percent. By purchasing an energy-efficient clothes washer and dishwasher, you’ll greatly reduce the amount of energy needed to heat the water. Make the most of your dishwasher by operating it only with full loads. With laundry, you can often get it just as clean by using warm or even cold water to wash and cold water to rinse.
