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.

My sump pump stopped working just as we had heavy rains. I called 3 plumbers but none were available. It was easy to schedule a visit with Nixco. Jared came in as scheduled and was very efficient in explaining the problem and providing alternative solutions. I’m glad that I chose Nixco to replace the sump pump.

We discovered water flooding our basement and what appeared to be our walkout outside drain not draining. I spoke to their office at 7:15am, and Audie arrived just after 8am. Wonderfully quick response to our emergency. Audi was fantastic. He diagnosed the problem, offered options and pricing, and completed the work with great results. He was also very professional and friendly. We will absolutely use Nixco again for any future work.

I have been using Nixco for many years. I have never had a bad experience. I buy their annual service plan and it has really paid off for me. I woke up this morning to a backed up kitchen sink. Shawn Crank was here within 2 hours of my call. He fixed me right up, then did a health and safety check of my home. He was so professional, knowledgeable, and friendly. I wish I got service like this from everyone! I tried to add a second review but Google will only let me edit this one so let me say that Chris McClure has done FANTASTIC work on my house for years - he even replumbed my entire house years ago - have not had a problem since! Today he replace my whole house water filter. He is professional AND personable. A delight!

Saved by Nixco's Master Plumber John Krusling & Brennan - John quickly came up with a way to bypass the under-the-slab leak in my condo - and restored hot water to my bathroom. NO more cold showers there! After the leak locators found the nasty leak, John and Mason did heroic work drilling out the concrete, even had to have kitchen cabinets removed, butr they found the leak, replaced the pipes, filled the huge hole with concrete - took all day, but they got the job done, cleaned up, and restored my kitchen. Very grateful for their prompt, courteous, and thorough work - my house is "whole" again. Better than I had any reason to expect - Kudos to Nixco, John, and Mason!

I called Nixco because I was suspecting that I might have a busted pipe in the basement during the very cold days. Office staff is wonderful. They were super helpful and set up an appointment for the same day. I had to be at work, so I didn't meet the technician who came to look at the problem, but I had family members here who met him. I was quoted $1000 which I thought was due to the busted pipe, but once they opened the wall, they were not able to see any damage and the price dropped. Later, after I had paid, I looked at the invoice and noticed a charge that had not been mentioned. I called the office and spoke to Guy and he immediately removed that charge. Overall, I am very happy and I would use them again. I'm just not certain if the technician would have dropped the price had my friend who was here and knowledgeable about the issue not suggested that he run water through the pipe first to see if there was any damage. His impression was that the technician would have changed the pipe and charged me the initial quoted $1000.That's why I took off 1 star.

Chris McClure and he’s partners have helped me tremendously in my renovation to my condo. First I needed a new drain as I wanted two sinks in my bathroom no problem. Then he suggested and explained how we could install a shut valve in the house as we didn’t have one and also got a softener. He explained everything he did and then some. He then came out to help with a drain being off center. He came out fixed it and was in and out no problem. I totally recommend Nixco and Chris with any needed plumbing he and his partner were amazing. Thank you

Someone had dumped grease and oil down our large sink. Worse, they clogged it and did not let us know. When I found out about this, I contacted Nixco Plumbing, who came out the next day. Chris took care of the clog, cleaned/flushed the pipe and provided something to breakdown the grease. Our large sink is working perfectly and clog-free. I would recommend Nixco Plumbing for any plumbing issue!

Nixco is the absolute best! Their level of service is without peer in the industry. They'll let you know who is coming, a picture of the individual and some background on them. It personalizes the entire experience. Their plumbers are top notch, knowledgeable and friendly. Audie took care of us today and he and his apprentice on hand were wonderful! They kept us informed, did a thorough job and cleaned the entire area. They had to add a couple of additional steps to complete the job but didn't increase the cost unnecessarily. What a great company. Thank you Nixco!
