6 Advantages of Using a Tankless Water Heater

Many homeowners with a conventional tank water heater struggle with issues such as never having enough hot water, high energy bills, or simply poor performance. It can be frustrating when you need hot water for your shower and all you get is a cold greeting.

Here are some of the advantages of installing a tankless water heater:

  1. Energy-efficient: The water heater is only used when it’s needed, eliminating the standby heat loss of storage tanks.tankless water heater installation
  2. Unlimited hot water: Unlike storage tanks, tankless water heaters can deliver hot water on demand, allowing multiple users at the same time without running out of supply.
  3. Longer life span: Traditional heaters typically last seven to 10 years. Tankless heaters can last up to 20 years.
  4. Reduces risk of water damage: Tankless water heaters don’t store large volumes of water, reducing the risk of significant water damage.
  5. Improves water quality: As tankless water heaters don’t store large volumes of water, there’s no buildup of sediment, rust, or other water impurities, resulting in cleaner, fresher hot water.
  6. Saves space: Tankless heaters are wall-mounted and compact, taking up significantly less space than traditional tank units.

Is a Tankless Water Heater Right for Your Knoxville Family?

While tankless water heaters are great alternatives to conventional systems, they’re not for every household. Smaller families often benefit more from a whole-house tankless system.

You can also install point-of-use units under the sink to ensure all areas of your home are equipped with efficient, hot water.

Potential Tankless Water Heater Problems You Should Look Out For

Tankless water heaters are generally reliable. However, problems can still occur over time. For example, you may find that you’re not getting hot water, or your water isn’t as hot as it used to be. Another potential problem is flickering lights on your system, which may indicate insufficient amp capacity in your electrical panel.

What Our Customers Are Saying

"Adam Bunch and Salwan were our technicians. They were very professional, courteous, thorough, and we feel they did a very good job. They were both very personable, friendly, and genuinely take pride in their profession. We feel very confident in the work that they did. We have an older home built in the mid 1980s with old, failing hex water lines along with some copper fittings. We needed new lines installed and they did a good job with it. I would recommend them to other people. In comparison, the price is more expensive than some other businesses in this area for the same work, but we feel that the guarantee that comes with Pipe Wrench work brings accountability. We will use this service again in the future."

"Very timely. The first time I used this service I had a thermostat replaced in my hot water heater. They were quick and professional and was fairly priced. I'm in the middle of my second experience at a relatives home for hot water heater replacement. They were able to get a tech out for evaluation the same day we called (today) about a problem and have scheduled the replacement for the next day. The tech was polite, professional and advised us of all our options in a way that was easily understood. I highly recommend Pipe Wrench services."

Sasha N.

"Ryan and Tyler were fantastic! As soon as they got to our home they set expectations for all the work they were going to perform. They kept us posted on the status of the job throughout the time they were working and reviewed everything with us when the job was complete. They were professional, knowledgeable, and nice. I would highly recommend them and the team at Pipe Wrench for any plumbing needs! Although I hope we won't have to use their services again, if we ever have the need for a plumber in the future, they will be the first people we call!"

Katey M.

"They came on time with texts and calls ahead of time to ensure I knew who was coming (with a picture) and when they'd be there. Kyle was professional, personable and didn't try to sell me more than I needed. He worked with the scheduling to get me scheduled that evening, even though I couldn't be there for the install. The installation was prompt and they were clean (again with forewarning and pictures of who was coming). They are my new go to company. Thank you."

Mary W.

"Our technician showed up on time and very professional. This company never tried to take advantage of my older mom. Which some in the past have. Very thorough in explaining everything he did and the cost. They came the very next morning. My mom’s A/C had gone out the day before on a scorching hot day and week. I would highly recommend this company. Very good people."
