Hot Water on Demand

Expert Tankless Water Heater Repair, Replacement, Installation, & Maintenance

Conventional storage water heaters dominate the market as the most popular water heating systems in the United States. However, these water heaters are not the only (or most efficient) option available to consumers.

Tankless water heaters (also known as on-demand or instantaneous water heaters) heat water on demand. With no tank, less energy is wasted heating water, and there is no risk of running out of hot water.

At WyattWorks, we offer complete tankless water heater services in Charlotte, NC, including repair, replacement, installation, and maintenance.

What Is a Tankless Water Heater?

There are two main types of tankless water heaters: gas-fired and electric. Both types do not have a storage tank and will remain in a standby state until you turn on a hot water tap.

Once you open a tap, a built-in flow sensor detects water movement, activates the system, and the unit begins rapidly heating the incoming cold water. How fast you’ll feel the hot water at the faucet depends on your plumbing setup and distance from the unit; typically, it takes between 15 and 30 seconds, but it can take longer.

Benefits of Tankless Systems:

Endless Hot Water

Tankless water heaters heat water on demand instead of storing a limited supply. You can take long showers, run back-to-back laundry loads, and keep multiple appliances on at once as long as demand does not exceed the unit’s capacity.

Higher Energy Efficiency

Tankless water heaters do not run continuously. They consume a small amount of energy in standby mode to stay active, but no energy is wasted keeping a large tank of water hot, like in conventional units. This helps homeowners save money on utility bills and reduces overall energy consumption.

Longer Lifespans

Tankless water heaters can last 15 to 20 years with proper maintenance. This is nearly double the lifespan of traditional tank-style heaters, which last about 10 to 15 years.

Space-Saving Design

Tankless systems are much smaller than conventional heaters because they don’t have a bulky tank. They are most commonly installed as wall-mounted units, which saves floor space and keeps utility areas more open.

Lower Risk of Water Damage

Because tankless systems do not have a storage tank with gallons of water, there is reduced risk of corrosion, tank rupture, or sudden system failure. While tankless systems can still malfunction and leak, the overall risk and severity of water damage is much lower compared to traditional storage units.

Tankless vs. Tank Water Heaters

Feature	Tankless Water Heater	Traditional Tank Water Heater
Hot Water Supply	Provides on-demand hot water and can supply continuous hot water without running out.	Stores a limited amount of hot water (typically 30–80 gallons), which can run out during heavy use.
Energy Efficiency	More energy efficient—only heats water when it’s needed, no standby heat loss.	Low efficiency—water in the tank must be continuously heated, even when not in use.
Lifespan	Typically lasts around 20 years or more with proper maintenance.	Usually lasts 10–15 years before needing replacement.
Space Requirements	Compact and wall-mounted, making it ideal for small spaces.	Larger and floor-standing, requiring more installation space.
Risk of Major Leaks	Lower risk of major water damage because it does not store large amounts of water.	Higher risk of significant leaks because the tank holds dozens of gallons of water under pressure.

Tankless Water Heater FAQs

See More FAQs

What are the downsides of tankless water heaters?

Higher Upfront Cost: Tankless systems usually cost more to purchase and install than traditional tank water heaters. This higher upfront investment may not be ideal for some homeowners and is often the biggest deterrent when considering a switch.
Limited Output for Simultaneous Use: Tankless units have a maximum flow rate. While they can handle multiple appliances better than storage tank systems, too many used simultaneously can cause a drop in water temperature or pressure.
Possible Installation Upgrades: Switching from a tank system to tankless may require additional work, such as new venting, electrical upgrades, or gas line modifications, which can increase installation complexity and overall cost.
Maintenance Requirements: To keep the system running efficiently, annual professional maintenance is highly recommended. Tankless units are more complex than conventional tank-style systems, and servicing them often requires specialized knowledge and tools.

Should I get a tankless or traditional tank water heater for my home?

Both options have different benefits and trade-offs. Below, you can see which option may be the best fit based on your needs and goals:

Choose a tankless water heater if:

You want endless hot water
You have limited space in your utility area
You don't mind the higher installation cost
You're planning to own your home long-term
You want to save on energy bills and improve overall efficiency

Choose a traditional tank water heater if:

You prefer a simpler system
You have moderate hot water usage
You want a lower upfront installation cost
You don't mind running out of hot water during heavy use

Can I replace my tank water heater with a tankless model?

Yes, you can! Keep in mind that the replacement process is a bit more complicated and can sometimes be more expensive than replacing a tank unit with the same type. A lot will depend on your home’s current setup, and some components may need to be upgraded or modified.

What is the most common problem with tankless water heaters?

The most common problem with tankless water heaters is mineral buildup (also known as scaling) inside the system.

As water flows through the unit, minerals such as calcium and magnesium can collect inside the heat exchanger. This buildup restricts water flow and makes it harder for the system to heat efficiently.

If you notice reduced hot water flow, inconsistent water temperatures, system error codes, or longer wait times for hot water, it’s likely mineral buildup. Reaching out to a plumber for an inspection and maintenance service is the best way to prevent further damage and keep your system running efficiently.

Are tankless water heaters more expensive than tank heaters?

Yes, tankless water heaters are usually more expensive upfront than tank heaters.

Kathy Mendola

Technician Michael came out and checked out the kitchen faucet. He tightened it up and seemed to work better but after he left it started leaking again. He came right back out the next call and replaced the faucet. Everything works great now. Very happy with the service. Super friendly and received text update and confirmation timely.
Marie Rodgers

Thanks so much for the great work and awesome customer service given to us by Joe, Sammie and Walker.
Priscilla Davis

Joe and Sam came out and repaired a leak in the crawlspace that was occurring due to a blockage. They cleared the blockage and replaced some old cast iron pipe with pvc and cleaned up the bathtub which had backed up. Kudos! They also gave us information for crawlspace maintenance and set us up to have camera evaluation of our plumbing down to the street connection.
Doug

Brenden came out this morning and was able to quickly locate the source of our issue. He worked with the team to turn around a quote and get folks scheduled in 2 days for a main sewer line repair. Drew, Ryan, and Elijah came out and cut away a chunk of my driveway too dig down and repair the line. They did a fantastic job getting it back to working shape. They even offered to pour concrete to fill the hole they cut away, which is a service they typically do not provide. They were polite, friendly, and fast. I will be using WyattWorks going forward because of everyone's professionalism and thoroughness.
Jim Kallam

I had electrical work done, by Dawson. He was professional and personal. I highly recommend him
Christina Carlson

Phillip Lardieri was a true professional and did amazing and quick work to get us a new water heater after ours went out impacting our kitchen, bathrooms and laundry room. We are so appreciative to him as well as Sam who assisted and Hunter who did terrific work on a leak months ago. We will keep coming back to WyaytWorks for their quality, service and the most awesome plumbers in the industry. Thank you all!
Sarah Hamlin

I learned about Wyattworks from a review in the new edition of “Best Picks Reports”. I contacted Wyattworks about a leaking exterior faucet. Additionally I wanted to replace a non-operable garbage disposal. My initial contact with the company office was handled with pleasant professionalism. An appointment was scheduled and the Technician, Michael, arrived on time. Michael took the time to sit with me to discuss the issues I identified but we also discussed other areas of concern that he brought to my attention after a cursory examination of all the plumbing fixtures in my home. Michael removed the old disposal and installed the new one that I chose after reviewing options. The repair of the exterior faucet was more complicated, involving cutting through interior drywall to access the problem area. But Michael expertly corrected the problem and left the work areas as clean as he found them. I highly recommend Wyattworks if you are in need of plumbing services. They are consummate professionals. I was not pressured into any of the choices offered regarding products or services. They are just nice, polite people to work with. I believe they treated my home as if it was their home. I will not hesitate to call on them in the future!
S Gaskin

Mr. Phillip was excellent youngman to meet. Pleasant, and explained things with understanding. Thank you. Pricing quite expensive.
Deborah Giarratana

Grateful for Joe and the team’s quick response to my water heater and disposal breaking! I was amazed to get same day service— they had changed out the gas water heater and garbage disposal in just a few hours. They had to wait to get some parts delivered but they were not idle while they waited. They cleaned up and I am glad to recommend them. Thanks for your professionalism and timely service.
Diane

You guys were great!! Such awesome customer service from Brenden and Cole. Thank you so much for fixing my clog!! What a relief. I just felt bad you had to come out 3 times, but you still only charged the one fee!! Most excellent. Will definitely call you guys again if something else happens. Thank you so much!!!
Ayman Ibrahim

Man where do I start.. from Courtney answering our calls pleasantly and directing us to who we need to speak to - to Joe who handled our appointment and helped us with the financials and sharing his expertise when we needed it - to Ben the manager, who pulled with a smile and gave us multiple quotes WITH financing options and even waived the service fee (who does that?! 🔥) to Elijah and Drew who sealed the deal by coming in the rain and replaced our main plumbing line and treated my family and house with the upmost respect and care. Genuinely I see why the reviews are where they are, from top to bottom the process was smooth sailing. You can feel the care behind the staff of this company being family owned - I felt like I was apart of the family throughout the process and I highly encourage everyone to check them out!!
Johan C

My hot water heater failed and I called WyattWorks and they set me up for service the next day. They took all my details and when the technician came out he inspected my old heater and then provided me several options. Eric Irvin was very knowledgeable and friendly. He answered all my questions and helped me make the best decision for my financial situation and my homes future. They offer financing options for anyone that isn't rich and doesn't have thousands of dollars lying around. Eric got right to work and completed the huge job the same day. I'm more than satisfied and happy with the quality of work that was done and the efficient time it was completed. If I ever have future plumbing needs, I will reach out to WyattWorks immediately.
michael riordan

Phillip did a great job with routing a gas line for us to our fireplace. We appreciated how he explained everything to us. Reason I can’t give 5 stars is due to scheduling snafu caused in office. Otherwise, very nice people, great service
Stephen Toth

Fantastic. Very personable, thorough, and explained everything clearly. 2nd review - even better. Brenden, Drew, and Ismail (may be getting that name wrong) are absolute rockstars. Those gentlemen are all Five Star. First Class WyattWorks!!!!!
Paul B.

This time we needed WyattWorks electrical(used their plumbing services in the past and were extremely satisfied)--several dead outlets and wanted a full home inspection since we just bought this house. Dawson showed on time, was extremely knowledgeable, and explained our short term needs and longer term options. Overall a great experience! Congrats to Seth and team!
