"We had our water heater replaced by The Water Heater Company and the service was excellent from start to finish. The technician, Mike P., was professional, on time, and extremely knowledgeable. He explained everything clearly, completed the installation efficiently, and made sure the area was clean before leaving. My new water heater is working great. We really appreciate the quality of work and the attention to detail. We highly recommend The Water Heater Company especially if you want a smooth, stress-free water heater replacement done right the first time."

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"Ok so this man Giovanni is a rare find. Read his reviews they are real reviews. I had a problem no hot water and we had a new tankless hot water heater put in 9 months ago. So did some research and as soon as I read Giovanniâ s reviews I stopped searching. The review of the son being concerned that Giovanni was going to take advantage of his older mother is the main review that sold me. So this is what happen, I called and spoke to Giovanni around noon. He was going to squeeze me in around 2:30. He had other appointments. So around 1:30 a friend can to my house and I told her about the hot water so she said let me see. She started going into settings and with a few clicks it started working. I then sent Giovanni a text telling him what took place. He called me I told him what my friend did and walked him through the steps. He said all was good except to take off always running and put on intelligent, which I did. So now the next day I get home from work turned on hot water and just warm after 5/6 minutes of running. So thinking there was still the problem I text Giovanni and ask if he could come and look at it either today or tomorrow told him about the warm water. He then text me back saying that the intelligent needs to relearn when we use water. He also told me to turn on hot water in few different places in the home. And yes he was right the water got hot very hot. It just needs to relearn when we use hot water. I have paid this man nothing, he talk me out of having him come to my house because he doesnâ t feel there is a need for him. He told me it could take a week to learn, and if I did have problems to call him back. WHAT A GREAT GUY. I kinda hope it does break just to meet this incredible man. THANK YOU GIOVANNI. Need to update this review because I did have him come to my house for a feew liitle things. He quoted my $1,595.00 for 3 didderent fixed. The reason why I am writing this is because after he started the work he realize that one of the issue I had didn't need as much work as he first thought. He removed $400.00 from my bill. He could have said nothing because the issue was in the craw space and I would have nevered known. That is a really great guy and an incredible plumber without a doubt. Would refer him to anyone and everyone!"

"Lonnie is an awesome plumber! When I first got my house he installed new water valves for my washer. Just recently he came to repair my water heater because it was leaking. He noticed I still had warranty on my water heater. Any other plumber probably would have charged me for a new one. I really appreciate his honesty. I would definitely recommend his services"

"Armando and his team were great, I was looking for someone to help diagnose a problem with my refrigerator and they contacted me and came to my house the same day to fix the problem. Armando also worked with me to offer the service at a reasonable price which was much appreciated. I will definitely look to Fix It Quick for any other plumbing needs I have in the future, and would recommend them to anyone else looking for this service."

Water Heaters questions, answered by experts

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions. 

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.
