Tankless Water Heaters in Knoxville: FAQs

Tankless water heaters should be installed by a professional, as they require someone with specialized expertise and training. If you’re interested in a tankless water heater installation, a water heater specialist will first check your ductwork, water and fuel sources, and then remove whatever existing unit you have.

Tankless water heaters also must be properly sized for your home to work efficiently. If you have a larger home, you might risk overloading the unit when multiple people are trying to use hot water at the same time.

If you’re considering replacing your old water heater, hire a company specializing in tankless water heater installation in Knoxville. For additional information on how the heater specialists at Happy Hiller can help, contact us today!

Several factors can influence the recommended frequency of tankless water heater replacement, including the quality of the unit, how often it’s used, and whether or not you perform regular maintenance.

Tankless water heaters have a longer lifespan (up to 20 years) than the typical tank-style heater (10-12 years). If you have a high-quality unit and take good care of it, you could get 25 years or more out of it. So if you’re considering replacing your old water heater, switching to a tankless heater can be a great choice.

Tankless water heaters are typically more expensive than a conventional tank unit, but between rebates, energy efficiency, and the longer lifespan, you’ll often save money in the long run.

If you’re interested in a new tankless water heater, in Knoxville, trust the experts at Happy Hiller!

Tankless water heaters are generally very reliable, but like any mechanical device, they can experience problems from time to time. Here are a few common issues that you might encounter with your tankless water heater:

  1. Lack of hot water: This can be caused by a variety of issues, such as a clogged filter, low gas pressure, or a faulty thermostat.
  2. Leaking: A leak in the unit or in the water or gas lines can cause damage and should be addressed immediately. Gas leaks are very serious and can cause carbon monoxide release.
  3. Strange noises: Popping, banging, or whistling sounds can indicate mineral buildup in the unit, which can be cleaned by a professional.
  4. Error codes: Many tankless water heaters have digital displays that show error codes when a problem is detected. A professional will be able to diagnose the issue based on the code.

If you have a concern, it’s best to contact an expert in tankless water heater repair in Knoxville. They’ll be able to diagnose the issue and get your hot water flowing again in no time!

Tankless units can be up to 30% more efficient than their tanked counterparts. Here’s why:

  • Continuous hot water: A tankless water heater heats water on demand, so you’re not wasting energy keeping a tank of water hot all the time.
  • Longer lifespan: Tankless water heaters can last up to 20 years, which is longer than traditional tank water heaters.
  • Energy savings: Tankless water heaters can save you up to 30% on your water heating costs.
  • Lower emissions: Tankless water heaters typically have lower emissions than traditional tank water heaters, making them more environmentally friendly.

Keep in mind, the energy efficiency of a tankless water heater in Knoxville also depends on the size and quality of the unit, the fuel source, and how it is installed and maintained.

Overall, in Knoxville, a tankless water heater is a great way to boost your home’s energy efficiency and save you money on your monthly utilities!

Regular maintenance is important for keeping your tankless system running efficiently and safely. It’s a good idea to have a professional provide water heater services at least once a year.

Here are a few things that provide when we service a tankless water heater in Knoxville:

  • Cleaning: Tankless water heaters need to be cleaned regularly to remove mineral buildup, which can decrease efficiency and cause damage over time.
  • Filter Changes: Some tankless water heaters have filters that need to be cleaned or replaced on a regular basis.
  • Gas Line Inspection: We’ll check the gas line to the unit for any leaks or damage, and repair it if necessary.

By taking care of your tankless system, you can help ensure that it runs safely and efficiently for many years to come!

We used Hiller for a total home repipe and they took a lot of care with the process. We are super happy with the end results and while we do have some dry wall repair they definitely did great to make straight lines to make repairs easy! We had Austin, Charlie, and Q come out and they did such a great job. My clean up was very minimal and I could tell they took great care with everything which I appreciated. I have two small daughters so keeping a clean home is important to me. I am so grateful to be a “happy Hiller” and would recommend them for plumbing services AND HVAC. Close

I have used Hiller Plumbing & Electrical quite a few times this year, starting with the installation of a water filtration system to now having my sink uninstalled and reinstalled and in between fixing a few leaks and checking over the general plumbing as well as electrical outlets in my house. Throughout all of it, a couple of glitches arose, but they more than made up for them. I am totally impressed with their professionalism and wanting to make sure everything was perfect and just the way I wanted it! The Customer Service is amazing and the workers are professional, capable, and friendly. I couldn’t be happier! Close

The technician Jacob was excellent. He was courteous, knowledgeable and did an outstanding job in a timely manner. I was taken aback when charged a $99.00 fee for Non Truck Stock Sourcing (which I described to them with a picture of the switch when scheduling) and $25.50 for Non Truck Stock Material and $99.00 Switch or receptacle replacement for a grand total of $223.50 for the job of replacement of a light switch. The services were quite expensive. Close

Excellent response in emergency and Jack was professional and efficient. The charge of $179 to flip a lever on my cutoff valve in a space that was approachable on foot (no crawling around to get to it) was outrageous but I had no choice. I will forever resent that charge but all else was the usual good service and reasonable repair charges for a work-in call for a Saturday emergency. Now that I know where and what it is I will turn the intake off myself if the need ever arises. Close

Our AC stopped cooling in the middle of the night. I contacted Hiller the next morning. Haleigh was extremely helpful in getting us scheduled for same day repair. Lance got here earlier than expected and immediately found what the issue was. He was very professional, courteous and efficient.

Ryan was great! He was on time, diagnosed the issue quickly and took his time while fixing. He explained everything along the way and even told us about Hiller's tune up service.

Woke up in the morning to find out I had no hot water. Thinking my pilot light was out, I went up into my attic where my hot water heater is located to relight the pilot. To my surprise, not only was the pilot light out, but I had standing water in my drip pan and a flowing leak from my temperature relief valve. Knowing I needed immediate help, I scheduled an appointment with Hiller online around 7:30 AM, and by 1:00 PM, William Gough arrived at my home to assess the situation. He quickly identified my water pressure was extremely high (120 PSI) and explained I needed to get it fixed immediately, not only to solve my water heater issue, but to prevent any further water related damage that could occur with that high level of pressure. He mentioned he could schedule a new heater to be installed if I desired it, but thought it might be possible to flush it and get it back into working order instead of replacing it, especially once I had my water pressure issue taken care of. He scheduled his team to come out to further evaluate and perform the required services. Later that day, Frank Croce and Chad arrived at my home earlier than their scheduled time. Upon further inspection, Frank found that water and sediment had already damaged the water heater insulation and its bottom (see photos), and he recommended a full replacement - he and Chad could do the flush and repair on it, but I would be on borrowed time before it started leaking again. I took Frank's advice and went ahead with replacing the water heater. Frank and Chad immediately got to work on installing my new water heater, as well as replacing my pressure regulating valve on my main water line downstairs to solve my water pressure issue. Within a few hours, they had me all fixed up (see photos of new water heater and PRV). I now have 60 PSI water pressure, hot water, and most importantly no leaks! Frank, Chad, and William were an absolute pleasure to work with and I truly appreciate all of their help. I'm extra appreciative because I understand working in a hot attic is not easy or comfortable, and not once did they complain about it even though they had every right to. All of these gentlemen went above and beyond the call of duty and deserve recognition for it. As a first time customer of Hiller, I was extremely impressed and will most certainly be calling on them for other services in the future. I hope Frank, Chad, and William will be the ones helping me again as well. Thank you, Team Hiller! Close
