Best Indianapolis Tankless Water Heater Repair and Installation

Water heating is the 3rd largest energy user in the home which means that choosing an efficient water heater is very important to your budget. If you’re looking for a new water heater, it’s a great time to consider a tankless water heater.

So, what is a tankless water heater? Let’s start by understanding what a traditional water heater is. Most people have a water heater that has a storage tank filled with water. That water is continually heated to the temperature that you have selected so that it is available whenever you need it. The problem is that it is being heated 24/7, and you are probably only using water a small fraction of that time. So you’re paying to keep water heated when you don’t need it which means you are using more energy and paying more in utility bills.

A tankless system doesn’t have a storage tank. It is able to heat water quickly and deliver it to you when you need it… on demand. You will save on your energy bills with this more efficient way of heating your water.

There are some definite advantages to tankless water heaters…

  • Up to 40% more energy efficient than a traditional natural gas water heater
  • Up to 55% more efficient than an electric water heater
  • Shuts-off automatically when hot water is not needed… saving energy and saving money!
  • Compact wall-mounted unit with a life expectancy of 20 years, whereas hot water tanks usually last around 10 years.
  • Water hasn’t been sitting in a storage tank that likely contains sediment.

Tankless water heaters are a larger upfront investment than traditional water heaters. However, when making your decision, you should consider more than the initial price tag. With the energy savings and the longer lifespan of a tankless system, you’ll probably come out ahead over time when you invest in it over a tanked water heater.

Tankless water heaters should be installed by a licensed plumber. If you are replacing a traditional water heater, you will need an experienced plumber to safely remove your current water heater and connect you tankless unit. This isn’t a do-it-yourself project.

Energy Efficiency

The energy efficiency of a storage water heater is indicated by its Energy Factor (EF). The higher the EF, the more efficient the water heater.


You may want to save money with a less expensive traditional water heater, but don’t ignore the operating cost. You may save money at the cash register but pay more to the utility company.

Installation and Maintenance

If your tankless water heater is not installed properly, it may not operate at its optimal energy efficiency, meaning you won’t get the energy savings that you should. Proper installation depends on fuel type, climate, local building code requirements, and safety issues. Therefore, it’s best to have a Mr. Plumber technician install your demand water heater.

Benefits of Tankless Water Heaters

Longer Life

A tankless water heater system will provide hot water for about 20 years. That’s about twice as long as a traditional water heater which typically operates for about 10 years.  So, you won’t need to re-invest in a new water heater as soon with a tankless system.

Compact wall-mounted unit

Tankless water heaters are compact and mounted on the wall which means they don’t require as much space as a traditional water heater. A tankless system is a great option when the physical size of a new water heater won’t fit in the available area. Plus, by eliminating the traditional water heater, you’ll free up a lot of space for other uses.

Endless hot water on-demand

Since a tankless system heats water as you need it, you don’t have to worry about running out of hot water when you’re the last in the family to get a shower. You’ll still have as much hot water as you want.

Save Money

A traditional water heater is always using energy to heat and reheat your water. Why pay to heat water when you don’t need it yet? And why pay to keep it hot when you didn’t need it in the first place?

Less maintenance

Sediment build-up and corrosion are not big problems for tankless water heaters like they are for tanked water heaters. Plus, maintenance doesn’t include draining and refilling a 40 – 50 gallon tank.

Hard hard water can harm your water heater and make it less efficient.

85% of the country has hard water according to HomeWater 101, and Indianapolis has some of the hardest water in the country.

What is hard water?

Water hardness is the amount of dissolved calcium and magnesium in the water — hard water is high in both calcium and magnesium. The reason you can feel the difference on your skin is because soap reacts with the calcium to form soap scum. This results in the need for more soap or detergent to get things clean. And that’s where the term “hardness” came from… it’s hard to wash in.

The calcium and magnesium in hard water cause problems in your home such as:

  • Glasses and dishes remain white filmed and spotted even after cleaning.
  • Clothes can look gray and dingy because of reduced “sudsing” action.
  • Clothes don’t last as long because of the harsh minerals in hard water.
  • Clothes can feel stiff or harsh.
  • The taste of tea and coffee can be affected by hard water.
  • Clogged pipes and reduced water flow can be caused by hard water.
  • Film and scale can accumulate on tile and bath/kitchen fixtures.
  • Your skin can feel dry from an invisible soapy film left on it.
  • Your hair can look dull and limp from excess filmy shampoo residue.
  • The life of your water heater can be shortened by deposits of scale.
  • Utility bills can increase due to accumulated scale in the water heater because scale is a poor conductor of heat which increases the energy needed to heat water.

Client Reviews

“Your service technician, Jason Lee, installed a Rinnai tankless water heater and Easy Water 2000 system at our home on 3-30-09. We want you to know what an outstanding job Jason and his crew did for us! Our old water heater died on Saturday, 3-28-09. We spoke with Jason on the phone that day after calling your emergency service. Jason was not able to come out to our home that day, but he took the time to discuss our needs and explain the Rinnai system to us. He also directed us to the Rinnai web site to further research this option. When Jason came out to our home on 3-30-09, he again took the time to explain the Rinnai options as well as the Easy Water 2000 system and benefits. Once we made our decision, Jason assembled his crew and immediately got to work. The entire crew was courteous and efficient. Most impressive was Jason’s willingness to miss an evening class that he is taking to finish our job! Having been without hot water for two days, this gesture of dedication was greatly appreciated by our family! We are extremely happy with the products that Jason recommended and installed and the experience with Metzler’s Mr. Plumber was exceptional at all levels. We will be happy to recommend your service to all our friends and neighbors.”

Last year was a tough year as my son passed away. Two weeks later my water heater began leaking ruining the kitchen floor and bedroom closet. If that wasn't bad enough, our AC stopped working at the same time. Mr. Plumber was at my house until after midnight on a Sunday night to make sure we had hot water. Oh yes, Williams was on site and repaired my AC. It truly was a fragile time and the professionalism along with the compassion from both Mr. Plumber and Williams Comfort Air employees has created a life long client to my plumbing and HVAC needs.

“It was my good fortune to have Carl as the installer of my sump pump this past June. He was on time, polite, and willing to talk to my son in Chicago about the installation. My husband of 37 years had recently died, and I was not versed on sump pumps or their installation. My son wanted to be sure the installer was the right kind of guy to be dealing with his grieving mother. Carl explained things not only to me, but also to my son to both of our satisfactions! I was so impressed with his professional appearance and attitude that I was not alarmed by the fact that a “stranger” was spending the day in and out of my house! I immediately recommended Williams Comfort Air and Carl in particular to friends who were in need of plumbing services, too. The whole process was pleasant and I’m still pleased with my sump pump. Then on one of the hottest days of the summer (July) Frank and Ryan were directed to take out my 32 year old furnace and install a new one. Having already used Williams Comfort Air for my sump pump installation, I expected a certain quality in the workers and their workmanship. Frank and Ryan did not disappoint me! They worked hard all day, had lunch with me, and continued working the rest of the 95 degree day! Once again, I felt comfortable with the two of them in my home. They were respectful and thorough with all that they did. I did recommend the company to my pastor and his wife because I felt that they would get good service from a reputable company and professional service from the guys in charge of the installation. Frank and Ryan even came back another day to show me (again) how to program the thermostat! Part of the “comfort” of Williams Comfort Air is being comfortable with the company and it employees. Both my experiences with them have proven to me and my son that they adhere to the highest standards.”

"They replaced the entire sewer line from the house to the street using a technique called “pipe bursting” where they pull a new line through the old line. We used a coupon where for $93 they freed up a clog in our old line and put a camera down the line to figure out what the problem was... I like that they didn’t have to dig up my yard for this particular technique..."

The below is a Facebook posting from Mardi. All of you exemplify A Winning Team! “I had a water pipe give way in my older home on a Sunday morning, so I shut off all the water to the house. Williams Comfort Air does all of my heating and air and was coming on Monday morning for my bi-annual service. I knew they did plumbing too as Mr. Plumber, so I waited to talk to my technician, Allen. He handled the whole thing. He called it in for me, explained the gravity of the situation and got me help within a couple of hours. Thank you Allen! Because my home is on a slab and the old corroded pipe could not be fixed as it was, my sandstone floor would have had to be jackhammered up and I didn’t want that. Supervisor Mike and I looked at all of the options and also looked at all exposed pipe in the house. It was all showing signs of leakage in several places and heavy corrosion, so I opted for having the entire house re-plumbed overhead. I also chose to replace everything that processes water in my house. I got hot-water-on-demand, a rust filtration system (rusty well water), a new water softener, new R.O., a new comfort height toilet and had some inconvenient piping rerouted to the gas dryer and to the outside hose bib. As you can imagine, this was a major expense and it took three and a half days, plus extra evening hours, because the guys really cared that I have water as soon as possible. It was done so well that I was thrilled. My house is safe now and my water is right for the first time in 20 years. I didn’t feel bad at all about the expense. I had three or four big Williams vehicles in my driveway every day and three to five Williams technicians every day and every one of them was so highly skilled that I was constantly impressed and in awe of their skill. Not only were they top-notch at their jobs, but they were fun to have here and I actually missed them when the job was done. We all hugged when the job was over. Thank you Mike, Jared, Bob, Brandon, Jeff, John and Dan. Thank you, thank you, thank you! You made me very, very happy, but I know that you know that.”
