Pros and Cons of Tankless Water Heaters

It is time to replace your water heaterIf you’re dealing with poor performance, rising energy bills, or an expensive upcoming repair, the answer might be yes. You could always install another traditional storage water heater, but why not consider tankless water heating? Learn the pros and cons of this modern alternative to help you make the best decision for your family and budget. 

Benefits of Tankless Water Heaters 

If you’re open to trying something new, a tankless water heater could benefit you in the following ways: 

  • Energy savings: Since tankless units produce hot water on demand rather than storing it 24 hours a day at 120 to 140 degrees F, you can expect to see a noticeable dip in your utility bills. In fact, going tankless can save you between 11 and 69 percent on water heating! 
  • Endless hot water: If you have ever rushed through a shower because the water turned cold halfway through, you can appreciate the concept of endless hot water. With a tankless unit, your family can shower one after the other, and the last shower will be just as hot as the first. 
  • Space savings: If you own a small townhouse or condo where space is limited, you could benefit from a tankless water heater’s small dimensions. At about the size of carry-on luggage and mounted to the wall, a tankless unit frees up room in your basement or utility closet, giving you more storage space. 
  • Long lifespan: While storage water heaters last about a decade, tankless models can serve your home for 20 to 30 years! Just make sure you keep up with routine maintenance to encourage the longevity of your tankless unit. 

Limitations of Tankless Water Heaters 

If you decide to go tanklessmake sure you understand the limitations first. 

  • Flow rate restrictions: A traditional storage tank offers 7.5 to 9.5 gallons per minute (gpm) of hot water, but a tankless water heater is limited to 2.5 to 5.0 gpm. This means it can only handle one or two hot water activities at once. 
  • Slow heat-up time: After you call for hot water, it takes a moment for the tankless unit to turn on. Then, it takes time to calibrate how much heat is needed for the current flow rate. These factors mean you wait a little longer at the tap for hot water. 
  • Higher upfront cost: Expect to pay a bit more to purchase and install a tankless water heater. Fortunately, thanks to its impressive efficiency and long life, you should more than recoup your investment over the unit’s lifetime.
