Factors to Consider Before Choosing a Tankless Water Heater

Going tankless has several benefits: they are energy efficient, they save space, and they can last 20 years or more if properly maintained.

However, while it may seem tempting to choose a tankless unit once your old water heater has broken down, there are some important factors to consider before you decide to purchase a tankless water heater.

Additional Upgrades

Electric tankless water heaters have a larger electrical demand. Most units will require at least 120 or 150 amps, while a typical household’s combined electrical capacity is 200 amps. Most homes that opt to go tankless will likely need to upgrade their entire electrical system to accommodate the new water heater’s demands.

Tankless water heaters running on natural gas or propane will need larger gas pipes to handle the greater volume of fuel. Proper ventilation is another concern; you may need to upgrade your current venting to ensure the safety of your home.

Greater Upfront Investment

When it comes to price, tankless water heaters are not as budget-friendly as their tank-style counterparts. You will need to prepare for a higher upfront cost, which not only includes the equipment itself but the upgrades to your electrical or gas pipe system as well.

Despite the larger upfront investment, tankless water heaters can help lower your energy bill in the long run. How much you save will depend on the type of water heater you install (electric, natural gas, or propane) and your household’s particular hot water demands.

Ready to Install Your New Water Heater?

Since the process of installing a tankless water heater involves additional upgrades to your home, interested customers are encouraged to consult with a licensed plumbing professional who specializes in tankless water heating.

Our experts at ACW Service Inc. will take the time to discuss your hot water needs, address any questions or concerns you may have, and walk you through what’s needed to complete the installation successfully.

If you are ready to leave your tank behind and move forward with a tankless unit, contact us to get started. We are authorized dealers of Navien tankless water heaters and can help you select the right model for your home.

What Our Clients Are Saying

Outstanding service! Installed within 24 hours of calling, amazing! Brian Chambers is a great guy! COVID-19 posture protocols with protective masks made us feel safe. Great price and installation only took a couple hours. Just an awesome experience. Definitely earned my future business!

Dorian Mastros

ACW INSTALLED SUMP PUMP AND BACKUP BATTERY. BRIAN WAS VERY KNOWLEDGEABLE ABOUT WHAT WE WANTED AND EXPEDITED OUR NEED IN A TIMELY AND PROFESSIONAL MANNER. I WILL DEFINITELY RECOMMEND ACW FOR FUTURE SERVICES.

R G

ACW was easy to work with. They called 30 minutes before arrival, showed up on time, worked quickly, and provided up front pricing. We will surely use them for future plumbing needs.

Ron Phillips

ACW's Service was quick to get to our home as our water heater that was leaking. He went to work immediately correcting the situation and getting a new hot water heater installed right away. Brian was very professional and thorough. He even went to each bathroom and kitchen sink and drained the air out of the pipes so we did not have to. I have nothing but positive things to say about this experience. Thank you!

Jan Martin

We called when we saw water pooling around in our utility room. ACW was able to come out within hours and install a new water heater with all the latest code requirements. We are very pleased to have our home back in working order so quickly and to have worked with such a great company! Highly recommend to anyone looking for a plumber.

Terry Smith

Brian was very professional, caring and timely in meeting our urgent repair need. He made himself available at all times and talked me through the crisis until he got there. Quality work and service.

Jesus Figueroa

The absolute best. I called Thursday evening freaking out because my water heater broke. Brian called me back later that evening and said that he can stop by the next morning to take a look. He came and he took care of everything immediately and at a very reasonable cost. Honest, kind, efficient and reasonable. I highly recommend them for all your plumbing needs.

Ruth Creamer

Thank you to ACW for responding quickly, arriving promptly, and calming my nerves instantly. They worked quickly and diligently to locate and then repair the leak in the ceiling that was dripping in my kitchen. Could not be happier that they were referred to me.

Amy A

Brian from ACW Service was awesome. I had a propane fireplace that wouldn't light. Tried to fix it myself with no success. He was able to fix the fireplace and keep it working. I was so grateful to avoid the expense of having to replace it. Fast response, impressive expertise, great attention to detail, and reasonable prices will keep me calling on ACW Service for all my plumbing and fireplace needs in the future.

Kelly OConnell

Would recommend ACW to do your plumbing. Brian C. is the bomb and not only professional, punctual and responsive, he's very polite. 🙂

Kim Pronobis

ACW was able to come out same day to repair the broken pipe in my basement. They had all the necessary material stocked on the truck and had my house back up and running in no time. I greatly appreciate the quality customer service and will continue using ACW in the future.

Randy W.

Ruth Creamer

Brian is a true professional! He came right in and identified the issue. Furthermore, he provided evidence of the issue. He did not waste anytime, and fixed the issues I was having. He gave me necessary advice to prevent future problems. Brian provided the quality service I was looking for.Much Appreciated ! -Brandon

Brandon Dent

Brian was responsive to my online inquiry and immediately provided a reasonable quote. He was also able to squeeze me in for an earlier appointment (to accommodate my schedule). I will definitely be using ACW in the future AND referring them to my friends in the area!!

Denice Crump

We came home in the evening and were shocked to find sewage in our basement bathroom. We called ACW at 8pm and Brian was out to our house by 930pm. We were very happy that he could come out immediately especially at that time of day so we did not have to take time off work. Brian was AMAZING! He was a true delight. He not only quickly unclogged our sewer but he was great with our kids. He let my very inquisitive son be his “helper” by holding his mini wrench for him. Five stars ALL THE WAY. Brian was even talked into a Trolls dance battle (Which he claimed to win) by my kids at the end of a long day and he obliged with a smile. Truly kind and professional! My kids even asked us this morning if Mr. Brian was coming over today! Highly recommend ACW.

Julie Jones

Brian was very friendly, explained what was needed to be done and how it cost b4 starting the job no hidden cost. After problem was found didn't take long to finish the job even with having to leave go and get extra parts. Cost was reasonable for time and materials for the repair work.

Dallas W

Our preferred plumbing company for our rental properties. On time, No call backs, upfront pricing, good quality work. Licensed and Insured. Locally owned and operated.

Michael Funk

Called on a Friday morning and they were able to squeeze me in the same day. It was a small job but they did a great job and my home was back to normal in no time. Very friendly.

Maya Benjamin

Brian was as advertised by my neighbors on a local app I use. He was professional, friendly, and took the time to explain everything in great detail. Everything went exactly as he said it would right down to receiving the invoice in my email with all warranty information. I was very impressed, and as my neighbors did for me, I will recommend ACW to anyone looking for a plumber they can trust.

Ray Evans

After seeing an article on ACW Services Inc. in our local newspaper, I contacted them for an estimate and possible work appointment. After the initial visit and price quote, Brian Chambers from ACW Services Inc. came to my house on Wednesday June 3, 2020 to replace three outside water bibs. He was very personable and professional. While doing this he found that one of the cut off values was not working properly, so he replaced it. I am very pleased with the outstanding quality of the bibs and the installation of them. I would highly recommend ACW Services Inc to anyone looking for the services they perform. He reminded me of the type of employee or owner that you want to deal with. Thank You again Brian. It should be mentioned that during the whole time Brian was at my house he wore a face mask (in view of the Covid 19 restrictions) and it was very hot outside.

Randall Baker

I called ACW Service to ask some questions about some plumbing issues I was having. Brian told me he would come take a look and fit me in the same day even though it wasn't an emergency. Brian came immediately and was professional and Informative throughout. He took a look at the issues I was having and provided a couple of options. He then told me if I had the time he could complete the fixes the same day. He went and got the parts and fixed all the issues. I have used other plumbing services in the past and ACW Service was by far the best and had the best prices. I highly recommend this company and will go to ACW Service for all my future needs!

Mark Price

Called on a holiday and was pleasantly surprised to reach an actual person. ACW was out to my house the next morning and located and repaired my leak. I appreciate how prepared and professional they were. I’m sure with this old house it won’t be my last plumbing problem so I’m glad I found this company to use from now on.

Vernon Jones

We've used ACW twice now, and both times they were knowledgeable, prompt, and thoroughly explained the issue so a layman could understand. Our first time was an emergency water heater leak (structural failure), and the next morning, we had a new system in place and were good to go. We could not be happier with Brian and the ACW team.

David Monath

Zach replaced our nasty old utility sink with a beautiful new one and he did an amazing job!! He was very professional, he showed up with gloves, a mask and shoe covers to protect himself and our family during these crazy times. Not only did he show up right on time but he anticipated our needs and thought about things we never even considered, such as securing our hose from our washer to the utility sink. We will continue to use ACW for all of our future plumbing needs.

Christa Nairn

BEST experience I’ve ever had with a plumber! Very fast response time, showed up at the time they said they were going to. Took the time to explain what was wrong and how they were going to fix it- and actually did! Our bathroom is 100% fixed with no issues.Would highly recommend for any of your plumbing needs.

Travis Pop

Thank you to ACW Service for coming out during a pandemic and handling our plumbing emergency like true professionals. We greatly appreciated the use of masks, gloves, sanitizer, and them wiping down the work area very thoroughly. It was our first time using them and we will recommend them to our neighbors, friends, and family in the future. Great job!

Cheryl Lindsay

We had a significant water issue in our house. They had a timely response, provided an accurate quote, and provided top notch work. We have used them for additional work as needed after our impressive first time. Definitely recommend. Trustworthy and fair.

William Rector

Emergency call for a leaking valve in my master bathroom. ACW had an experienced, knowledgeable plumber out within hours. They took care of my problem and took a look at all the plumbing in my house to see if they could notice any potential issues. I appreciate the professionalism and willingness to go the extra mile. Very happy and highly recommend these guys.

Fred Barnes

I contacted ACW about the water in my shower not shutting off. ACW responded quickly and sent a plumber almost immediately. They were extremely friendly and knowledgeable. My shower was fixed in no time! I would certainly recommend ACW to anyone in need of plumbing services and will undoubtedly contact them in the future for all my plumbing concerns.

Paul Wehausen

ACW is Awesome!! I had an emergency at my tenants home with the water heater leaking. I found ACW in my neighborhood app. I called and got an immediate response. Brian was very professional and knowledgeable about his craft. If you need any plumbing repairs, I highly recommend ACW Services.Sign😉One Happy Customer!

Carla Brockenbaugh

I recently had my garbage disposal replaced by ACW Service Inc. What a pleasant and positive experience I had with this company. They were polite, knowledgeable and extremely helpful in answers my questions/concerns in an extremely timely manner. The technician who replaced my disposal was very friendly and provided me details with what he saw, along with what needed to be fixed. My disposal was fixed within the hour and works great! I highly recommend ACW and will be referring them to my friends and family. This is one happy customer!

Deanna Evans

ACW provided excellent service at a fair price for the clogged bathroom drain. I was able to get an appointment the next day and on Christmas Eve at that. Brian provided prompt service and quickly unclogged the drain. Thank you for a job well done!

Chrissy Killillay

Great Company! Read their other reviews. I can't recommend them enough. You will be very pleased you called ACW. Brian with ACW was very professional. He was on time, provided upfront pricing, was the lowest cost, and he did a very professional job! You can tell he takes pride in his work. My father had his hot water heater replaced less then 24 hours after the initial call. Outstanding Value!!!

Olin Straus

I cannot properly verbalize how happy I am, that THIS company got referred to us. My boyfriend and I bought a house on Monday... the first things we moved in were the washer & dryer... within 8 hours of officially owning the home, the hot water hookup pipe busted. Lucky for us, Brian was out within 30 MINUTES... at 7PM! He did an amazing job of calming our nerves, as well as (obviously) quickly fixing the issue. Not only that, but he actually stayed to hook up the washer & dryer AND make sure they both worked properly, before he left. These days, it's extremely hard to find quality service. Often times, when you do, they have a terrible or nonexistent personality. Not Brian; he was as friendly and personable as can be! We are keeping his business card in the safest possible place, because if anything else goes, he will certainly be the person we call. Thank you, again, Brian!!!!

Erica Johns

I needed a new dishwasher installed recently and their service tech arrived promptly. Zach was very professional and courteous and completed the install quickly. I would highly recommend ACW Service. I have called them many times over the last 20 years and they always provide excellent customer service and workmanship.

Jenny Ross

Thank you ACW Service and Brian Chambers for the work you recently completed in my house. I had a water leak from an unknown location and ACW Service arranged the necessary testing and performed the repair in a timely and professional manner. Brian was very punctual and courteous. I highly recommend ACW Services and will be using them for all my future plumbing needs. Well done.

Ma Beitzell

ACW was on time and extremely knowledgeable. They helped us avoid future issues with our well water system that other companies never mentioned and hadn’t included in their quotes. It turns out that a water heater isn’t just a water heater. They never talked down to us and kindly helped my wife and I understand the potential issues that doing it the wrong way could’ve caused. I can’t recommend ACW Service enough - Price - Quality - Incredible Customer Service all in one place! Thanks again to the ACW Team for getting us back to warm showers!!!!

Richard Williams

I called ACW Service for an emergency, when I came home to a leaking water heater. When, my main shut off valve didn’t work, ACW shut off the water at the street and was able to replace my valve. ACW Service was professional, knowledgeable and efficient. The prompt response saved me. I would definitely recommend ACW to friends and family
