There are a variety of reasons you may want to consider a tankless water heater. But whether it be space savings, energy efficiency, or the idea of having hot water at all times, there are more things to consider when making your decision.

First, I will list the advantages associated with a tankless water heater, but it is important to consider the cons as well, so please read through the entire article. Having said that, I have made all the important points bulleted, or bold for all the skimmers and scanners.

The Advantages of Tankless Water Heaters

Energy Savings

Heating the water in your home is typically the third-largest expense, and accounts for roughly 14% to 25% of a home’s energy usage. Tankless water heaters can save roughly 50% of your water heating costs.

Never Run Out of Hot Water

A gas tankless heater can deliver a steady supply of hot water at a rate ranging from 2 gallons to 5 gallons per minute. Essentially, the units never run out of hot water as long as hot water demands stays below the heater’s output.

Durability and Versatility in a Small Package

Tankless water heaters are durable as they have a life expectancy of over 20 years.

The unit can also go almost anywhere in the house, and can also be installed outside on a wall. Tankless heaters are much smaller than conventional heaters. So, there is considerable space savings when you choose tankless.

Cons for Tankless

Higher Unit Cost & Installation Cost

Tankless units cost roughly twice as much as traditional storage tanks.

In addition to the higher unit cost, installation for the system and the necessary piping is also increased. There is also a need for adequate venting, which is also an added cost. In other words, when installing a tankless heater in an existing home where there used to be a conventional water heater, there is much work to be done that adds costs that need to be considered.

Will a tankless water heater ever save enough energy to justify its higher cost purely from a financial standpoint? Best answer: Probably not.

Not Enough Output

In the advantages to tankless systems listed above, never running out of water is mentioned. That is not entirely accurate. If demand exceeds the unit’s output (someone is in the shower, while another person is washing dishes, and the washer machine is running all at the same time*) there will be a shortage of hot water.

*Please note that each unit’s output varies by specific model and very well may be able to meet and exceed your specific demands.

Quick Summary

Depending on what weighs heavier on your decision, a tankless water heater may be a perfect choice for you, but it also may not be a great fit for you.

If energy savings tops your priority list, then tankless is for you. But if economy, and times of peak demand are of more importance, then you may want to approach purchasing a tankless water heater with caution.

Let’s be honest: Nobody thinks about their plumbing and heating until there’s a problem.

What most people don’t realize is that most of those problems can be anticipated and often avoided with regular maintenance – usually at a far lower cost than a repair or replacement.

“This past week I had the need for a plumber and I reviewed the telephone book and selected from the advertisements your company to attend to the matter. The company sent Austin Steinbach to attend to and review the problem. He is a very knowledgeable young man who communicates well and does his work in a very thorough and professional manner. I was very satisfied with his service. Mr. Steinbech is a credit to your company. Very often in communities someone asks whether they are aware of a plumber or other technician that can be recommended. In this regard, I am comfortable in recommending Mr. Steinbech and your company. Thank you for the service rendered.”

“Quick & competent work done to high satisfaction. Darrell Begay provided quick service and very professional work when he came to install a new toilet seat. We had not been able to do the work ourselves, so it was a relief to have Darrell and Done Plumbing get here so quickly to take care of the task. We appreciate all Done as done for us”

“Just a note of thanks for being the Best plumbing and heating company. I have used you often and have been impressed every time. I called for a drain cleaning and was told a technician could come the same day. He arrived an hour ealier than was quoted, was very professional and did a great job at a very reasonable price with my coupon that he honored. I would never use another company and would recommend you to anybody that needs help. The technician that did such a great job was Austin, but every technician you have sent has been the best. Thanks again for such a wonderful company”

~ Karla W Golden, CO

“It was very professional, prompt & the technician explained many things well. Very happy throughout the whole process – from the customer service rep who answered the phone this morning to the technician explaining building codes to me.
