Are There Downsides to a Tankless Water Heater?

Tankless water heaters are a relatively new product that many homeowners don’t know about. Sometimes called an instant water heater, they don’t use a tank to store hot water. Rather, tankless water heaters warm water as it is used. But what are the advantages and disadvantages of this?

Energy Efficiency

Tankless water heaters are much more energy-efficient than traditional water heaters because it only heats water when you need it. This process is faster and much more efficient than keeping a tank hot at all times in anticipation of use, as a traditional water heater does.

Keep in mind the importance of calculating the correct maximum usage with your installation professionals to avoid problems. Because tankless water heaters use more energy in a short period of time, the system could become “output challenged” if too much stress is put on it.

Cost

One disadvantage of getting a tankless water heater is the higher upfront cost. They are more expensive to purchase than regular water heaters, and they often cost more on installation if retrofitting is required. However, the money you will save on monthly energy bills with a tankless water heater pays for the initial installation costs.

Lifespan

How long, exactly, will your tankless water heater pay for itself through lower energy bills? While a traditional water heater succumbs to wear and tear within 10 years, tankless water heaters last much longer. In some cases, a tankless system can last twice as long as its traditional counterpart, supplying you with lower energy costs for longer.

Water Supply

One of the best benefits of a tankless water heater is its ability to supply you with virtually unlimited hot water. A common problem with traditional water heaters is that it takes time for the tank to replenish its hot water. If you’ve ever been the last in the family to shower, you’ll probably agree that the hot water is worth the wait.

However, a tankless water heater is powerful enough to supply hot water instantaneously to whoever needs it, even allowing multiple showers at one time. With a tankless system, you can be sure that hot water will always be available at a moment’s notice.

Roberta C.

Very Knowledgeable

I recently had several plumbing leaks repaired and couldn’t be happier with the prompt service I received from Parker and Sons. They are very knowledgeable, friendly, reasonably priced, and do quality work. I would definitely recommend them to my family and everyone. I would trust them to repair any leak in the house.

Stacey C.

Amazing Service!!!

Amazing service!!! Called and came the same day within 2 hrs. Our toilet had to be re-fitted and snaked. They did a beautiful job on the re-fitting and got the large piece of plastic out of the toilet. Will definitely be recommending them to friends and family. Great service, great people, hard to find these days!!!

Shakira C.

Excellent Service! We had some work done on our kitchen and Parker and Sons were able to come out to our house and help us with our remodel. Great guys and great service. I would recommend them to anyone needing a plumber service.

Brad B.

Great to Work With

Jim and his guys are great to work with. Had Parker & Sons come out to take a look at an AC unit at one of my rental properties. Unit is in the attic. Had to replace a coil on it and did a great job. Will definitely use again.

Jeff C.

Amazing Staff!

I have referred Parker and Sons to all of my customers and I would not think of referring anybody else. They have been great and very punctual. All of the plumbers and office staff have been amazing!

Miguel B.

Reasonable Prices

I was in good hands today with journeyman plumber Mark Rizley. He remained until all was better than before. He replaced a PRV and improved a mediocre repair recently done by another well known local company. The price remained reasonable despite the extra effort needed for the job. Well done Mark! Parker and Sons will be my first call in the future.

Todd D.

Fantastic Company!

This is a fantastic company with outstanding professionalism, quality of work, and customer service. While their prices are extremely competitive, their work doesn’t feel cheap like some of the companies you can hire of off Craigslist or on a FB yard sale page. This is a reputable company with proven work and licensed, skilled technicians.

Ben A.

Fair Prices & Excellent Work

Have used Parker & Sons 3 different times, once for a huge complex plumbing repair and twice for smaller jobs. Fair prices and excellent work/fast response time every time.
