Professional Tankless Water Heater Repair, Installation & Replacement in the Greater Cincinnati & Mason, OH Areas
Ready to begin enjoying all of the benefits from switching to a new tankless water heater? Call Nixco Plumbing Inc., your tankless water heater specialists, now at (513) 457-0915 to get started today.
A tankless water heater is an efficient option for your home that operates differently than traditional units. Tankless water heaters do not store heated water. Instead, they use heating elements to heat the water instantly as it runs through the plumbing. These units can be placed in nearly any type of home and provide more hot water at a faster rate.
Read all about us in our customer reviews and testimonials.
What Are the Advantages of Tankless Water Heaters Over Traditional Water Heaters?
One of the main benefits of the tankless water heaters we install is that they save energy. Unlike traditional water heaters, tankless units will only activate when there is a need for hot water. They do not run all day using energy and fuel just to keep unused water warm.
Another advantage is cleaner water. The tankless heater does not accumulate as much scale and debris as conventional tanks. Water does not sit in the tank for hours absorbing minerals and other substances.
A final large advantage is that tankless water heaters provide a consistent supply of hot water. The unit will continually provide heated water on demand for as long as necessary.
How Long Do Tankless Units Last?
The tankless water heaters we use at Nixco Plumbing Inc. are built to be very durable and long lasting. They require less maintenance than traditional water heaters and are much less susceptible to further issues.
The average tankless water units will last between 10 and 15 years—warranty included. Though the life expectancy is high, some units provide an even longer lifespan of 20 years or more, requiring a bit more maintenance. This is far longer than the average six to ten years for conventional water heaters.
Are Tankless Units Ideal for Larger or Smaller Households?
We can install a tankless water heater in any size home. They are designed for homes that are small to medium in size although this really depends on water use and the number of people inside.
Tankless water heaters can usually produce anywhere from two to six gallons of hot water every minute. This flow rate might not be enough to supply a large home where multiple people are all regularly using hot water at the same time as appliances. The real issue is how many people that live in the same house will need hot water at the same time. Tankless water heaters can support an average family without any problems.
Selecting the Right Size Tankless Water Heater
Figuring out the size of tankless water heater you need requires a little research. Tankless water heaters are rated by the temperature rise they can produce at a given flow rate. So, to get the right sized heater, you need to determine the flow rate and desired temperature rise for the heater’s application (whole house or remote application) on your premises.
- Step 1: Start by determining the maximum number of devices you want to run and their flow rates. Add up the total flow rate in gallons per minute to get the desired flow rate for your demand heater. This includes all dishwashers, showers, sinks, washers and tubs that you run at the same time. You can get a general idea of your devices’ flow rates by doing a simple Google search. If you’re running two showers at the same time, for example, you will need a tankless water heater with a higher average flow GPM (gallons of hot water per minute) than if you’ll be running a single shower.
- Step 2: Determine the required temperature rise. This is the difference between the incoming water temperature and the desired water temperature.
For example, if the temperature of your cold tap water is 55°F, and you want your water heated to around 110–120°F, you need a tankless water heater that produces a temperature rise of 55°F.

What Are Some Other Uses for Tankless Water Heaters?
Tankless water heaters are not just for sinks and faucets. We can also install units for a few other purposes. Tankless water heaters can be installed to pre-heat water for appliances like dishwashers or washing machines. They can be used to generate hot water for hot tubs or bathrooms not connected to the main water supply. A tankless heater can even be used to supplement a solar water heating system.

Shawn came out today and I couldn’t be happier with the service. He showed up on time and took the time to walk me through exactly what he was going to do. He’s obviously very knowledgeable and answered all my questions. I’m very happy with Nixco Plumbing and especially with Shawn. Would definitely recommend him and the company. Thanks Shawn! John

Audie Reed did my water heater install, and he was very professional and did a great job. It was a bit more than I was expecting to pay (almost $3500 for the tank and labor), but it does come with a 10 year extended warranty. Overall, very satisfactory service, and there was no pressure.

The whole process couldn't have been easier! I scheduled online and got confirmation that my desired date and time were available. On the day of the appointment, I got a text WITH A PICTURE of my technician, which is great for security. I knew that he was on the way. Todd and Paddy arrived in a branded truck and wearing uniforms. The quickly got to work and installed my new kitchen faucet without incident. They were professional, polite, and positively just what we needed. If this is what I can except in the future, I will not hesitate to use Nixco again.

Sean was very professional, knowledgeable and thorough. He was respectful of the property, wearing shoe covers while inside and laying out a drop cloth to set the toilet on while he had it removed. He was on time and was efficient.

Shawn Crank was just at my residence again. It has been 4 years. One thing did not change. Quality work. Fair price. But best of all, an honorable young man that truly cares about the job he performs and the people he takes care of. Thank you Nixco. Thank you Shawn.

Called Nixco on Saturday when we discovered we had a burst pipe that runs to the exterior frost-free faucet. They were able to come Monday morning to evaluate and address the issue. We had John & John and they were great! They texted when they were on their way and once here they clearly explained the process they would take to determine the fix, provided options & costs, and then did the work we agreed on. Really appreciated the company’s responsiveness and John & John’s professionalism I doing the work and explaining what was involved. Because the pipe was behind drywall they needed to cut the drywall to access the pipe. They explained this and took great care to make the cut as small as possible and even did it in a way that it can be camouflaged with a cold air return cover. (Note: this was not an emergency so waiting until Monday was doable. Nixco offered emergency service, but it wasn’t necessary in our case.)

We recently bought a new patio home and because of our previous positive experience with Nixco installing an expansion tank on our condo, we turned to them once again for our plumbing needs of our new home. John were fantastic in their customer service, professionalism and expertise in putting in a new sump and back-up sump pump for us. Afterward, I asked them about an expansion tank for our water heater, as I noticed that we did not have one. They had noticed as well. Two days later John & John were back to install an expansion tank, pressure regulator valve and making sure our water pressure was set appropriately. They answered all of our questions and were very thorough in their workmanship and making sure we were completely satisfied. Top notch service! We highly recommend them for any plumbing services you may need.

We've used Nixco several times now and never been disappointed. In fact, we've been quite pleased. Part of that is the fact we got the same technician a couple times and he knows us and we know him now. No idea if it's because of geography or chance, but we'll take it. Nathan is always on time, always explains what he thinks we need, tells us the cost up front, and leaves the place actually cleaner than he finds it. In a trade that gets a lot of bad raps, these guys are changing the narrative. Give 'em a shot. (Nathan has great sense of humor, too!)

I’m very impressed with the workmanship and cleanliness from NixCo Plumbing. Todd Reed and Paddy Omlor, my NixCo Service Technicians, were prompt, knowledgeable, and professional with troubleshooting the problem then removal/replacement of my old expansion tank with new. Todd & Paddy left the job site cleaner than it was when they arrived. I highly recommend NixCo Plumbing.

NixcCo Is the best. Take care of you, so professional. Prompt, always on time, and work with your schedule when trying to coordinate with other companies that aren’t as easy to work with. I will always call NixcCo first. Audie Reed was a pleasure to have working for us.

I had a broken pipe due to freezing temperatures. Nixco was amazing to work with. Very professional and responsive, both in person and on the phone. I had the pleasure of working with Shawn and Alex. They were excellent! Very knowledgeable and answered all my questions. In order to get to my broken pipe, they had to remove my bathroom garden tub. This turned into quiet an ordeal, but they handled it extremely well. I have to file an insurance claim and Shawn helped me get all the pictures and documents I needed for them. He offered to be available on the phone if the insurance adjuster had any questions. I wouldn't hesitate to use Nixco again and I highly recommend this company!

I was house sitting and discovered a leak in the basement, I freaked. I called Nixco and they sent out Audie Reed, the service technician, first thing in the morning. He went out of his way to help me with the mess and fixed the problem. He kept the price reasonable, which I appreciated considering the circumstances. I am going to use them with a few issues I have at my house.
