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.

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.

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!

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!

We had a fantastic experience from start to finish. They came out the same day to assess our leaking main water line and provided a very competitive price. The work was scheduled for the following week and completed efficiently. Todd, the plumber, did an excellent job overseeing the entire project and crew. The main line—from the meter to the washer room (main valve)—was replaced in just one day. Other reputable companies we contacted estimated it would take up to three days (with no water during that time) and quoted prices about 20% higher. We were also impressed with the responsive and helpful office staff. Todd and the entire crew were professional, knowledgeable, and easy to work with. This company clearly has the right people, expertise, and equipment, and they deliver top-notch service at a great value. Other small businesses should take a note.

Nixco was able to send someone out within a hour of calling for service. Shawn did a great job explaining why my floor drain backed up a second time in just a couple of months. He was able to clear the clog and gave me recommendations for keeping that line clear. I am very satisfied with the service provided and will definitely use Nixco again.

Jared McCall diagnosed our whistling sound while water was running as a pressure valve issue and replaced the part eliminating the annoying noise. Shawn Crank did an excellent job of diagnosing and addressing our sump pump issues. We had another plumbing company out to address the problem and the issue recurred 8 days later after they supposedly resolved the concern. Now the problem is actually solved. NIxco's excavation team replaced our sump pump drainage discharge line that had become reconnected from the main storm sewer line running along the streeet. Nathan Floyd did a great job diagnosing our low water pressure issue and he and Kyle did an expert job of replacing our water softener.

5 Stars for Chris! Our house is in need of some plumbing upgrades so we call Nixco for help. We were lucky enough to get Chris for a second time and as before he was so friendly, respectful, knowledgeable and a total professional. He explained what needed fixing, showed us the issues and gave us a straightforward quote with no pressure. Plus he checked and rechecked everything to make sure all was in order. Problems like this used to stress us out but knowing Chris is on the job is a huge relief! Truly the best in Cincinnati!!
