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.

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.

Although not a big emergency, we used the after hours service for a clogged disposal as we were having guests for dinner. We were contacted in a timely manner. John was professional, friendly and not phased by the flurry of activity in the kitchen around him. Pricing was discussed upfront The job was finished and cleaned up promptly. Definitely will use Nixco for future plumbing needs.

I went online yesterday to book an appointment. This morning, exactly at 8am, arrived Mason and Audie at my house. Mason did a fantastic job replacing the shut off valve beneath the kitchen sink. Both Mason and Audie were very professional and took the time to answer all my questions. I would highly recommend both gentlemen and Nixco Plumbing the next time you need a plumber.

Every service call we’ve had with NixCo Plumbing has been extremely professional. Called on Tuesday, Mason W and Kris B were out on Wednesday to provide estimates for what we thought was a serious water pressure issue raised by our RO water company. They tested and explained why their finding wasn’t as serious as we were told. There are items we have to discuss with our HOA before making any repairs/adding a pressure valve but I am extremely confident that NixCo will do a great job. There were a few other items we wanted estimates for (two leaky faucets, bathroom remodel/shut off valves needed and corrosion on water main). Mason and Kris checked those items out, explained what the work involved would require, then gave estimates for those as well. Very appreciative of their time and professionalism.

Our technician Shawn Crank showed up right on time and diagnosed and explained the situation of the sewer back up in the kitchen. He then fixed the flooded sink and to my surprise cleaned the kitchen sink, counter and floor. I was extremely pleased and can only recommend Shawn with NixCo. Plumbing. He went over and beyond of my expectations.

We experienced a water backup in the kitchen sink after not being in the home for almost 3 weeks. The kitchen was mostly flooded and the water seeped into the carpet of the dining and living rooms in the open concept condo. A neighbor recommended Nixco. We come down from Michigan, so were glad to get a recommendation. We called them and they sent Shawn out. Shawn was super friendly and professional! He saw the mess and also arranged for a restoration company right away. Shawn and his collegue did a wonderful job explaining what happened, fixing the issue, cleaning up and making sure that everything was left perfectly, including making us feel comfortable with the process! I would highly recommend Nixco, and especially Shawn! Thank you, guys!!

Nathan and Paddy came out to replace a pinched water pipe below my garage. They arrived when scheduled and completed it in one day, like they planned. They were both friendly and answered any questions I had. The job entailed jackhammering through the cement floor and digging about 4.5 feet down. They dealt with the challenges of the task. My water volume and pressure is now outstanding. As for the price, my condo association paid for it, so I have no knowledge.

We’ve had Chris McClure from Nixco multiple times. He’s always respectful, friendly, prompt and thorough. Today, he and his working partner, Paddy, replaced a sump pump in record time. They walked us through the operation and controls and cleaned up the work area. Highly recommend Nixco, Chris and Paddy.

John Krusling with Nixco Plumbing helped me complete my backflow testing today and he was a joy to work with. He was on time, friendly, and professional, even after I had to cancel my previous appointment when he was already on site to do the work. He was kind and understanding when I was clearly stressed, and made the whole process much easier. John is a great plumber to hire for your job. Thanks, John!

Nathan was fantastic! We had a busted hose bib that flooded our basement. Within two hours of calling Nixco, Nathan had arrived, diagnosed, and fixed the problem. We are very grateful for Nathan's kind and quick help in this situation, as well as his explanation of what went wrong and how to prevent it in the future. Thanks Nathan!

John, Jason & Greg came and fixed our sump pump lines that lead to the storm sewer. After they assessed our situation they came bk with a back hoe in a timely manner . They did an exceptional job! All 3 were very conscientious, extremely polite & professional and were able to fix our sump pump lines in the front yard. They operated a back hoe & even saved our sod! Once everything was finished they put everything back and our yard looks great w the sod placed back over the giant ditch they had to make. The new sump pump lines are operating perfectly. I would highly recommend Nixco Plumbing!

We were thoroughly impressed with Nixco and their service technician, Chris McClure! We talked to Becky (the receptionist) at Nixco and requested Chris, due to wonderful reviews online he had for his work! Becky had Chris scheduled to be at our house the very next morning. Our kitchen sink was completely plugged up, and he finally had to go up on the roof and unplug the line from there. We are very grateful to Chris, and highly recommend him if you have plumbing needs!
