"Tuesday in June 2022, 4:03 PM Received a call from my wife, that our water had stopped while my son was in the shower. 4:14 PM Placed a call to Quality Water (QW) for Service. Keep in mind they are a "24 hour" service, is what they say. Customer Service (CS) said when asked, for service call charges normally is $135.00. After 4 PM is when premium rates kick in, which is $229.00 for service call (not per hour) to get back up plus parts and I said I was okay with that because I did not have water. LONG STORY SHORT: they called couldn't be out that night and put me off till next morning. They called next morning, all crew out on a big job and can't make it till tomorrow-24 hrs. service? When they did, the plumbing was way different and after they came back out to change it, again as I had before, they didn't do like I asked and leaks. Charged me $2395.00 to replace a switch & 22 gal. pressure tank - very high, but they had me over a barrel. Check the picture of the plumbing I found after they left - I trusted them for years and was shocked of how I found it when it simple came straight in down and over to the tank like a square Z to this? No written estimate or receipt, I had to call to ask for it. As a former service manager, I can tell you this service manager, Aaron did not handle this correctly at all. In pre court resolution now, and possible small claims to rectify. This from a customer that used this company for a couple decades, but first time for 911 services - no longer using unless this is cleared to satisfaction. Take my advise, don't call them for 911 services because they will rack you over the coals and are NOT true 24 hour service. There is a lot more bulleted points I could add, but won't. I am a patient person, but they blocked both my phone numbers and the owner never called to solve, only left a response on Google reviews to give him a call to resolve and want to keep their rave reviews. They have my number and if cared, could have this taken care of long ago. Unfortunately, small claims are next, if not cleared up very soon."

"I hired Neli over a week period for 3 different appliances, my dryer, washing machine, dishwasher, and even kitchen sink! I had a fantastic experience: 1. I fixed my dryer with Thomas' excellent remote guidance, changing the timer and the switch! Fabulous guidance Thomas, with lots of money saved! I learned a lot in the process. 2. I determined that there was no dishwasher leak and in the process learned how to check for leaks and trouble shoot for some common repair issues. It cost $40.00 but as I had some water on the floor, I was ready to get a new dishwasher. Now, I am confident that it wasn't a leak and caused by putting in the dishes in a funny manner and not a repair issue. I am using the dishwasher now again with no problem. 3. I determined with Thomas' help that the washing machine had a major problem and could have spun out of control into my wall....no question, it was time to get a new washing machine! This was a well spent $40.00--I even got Thomas advice on purchasing a new washing machine and what to look for. 4. I checked the drainage on my kitchen sink and learned how to empty out the "trap" and that most likely, I am okay, but what to swap out if I have continuing issues with slow drainage. In the end, I saved lots of money, gaining and learning valuable experience! Absolutely fabulous service!"

FAQs for tankless water heater installation projects in Mansfield, OH

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
