"My 12-year-old water heater was on its way out, and it was finally time to replace it. Iâ ve always wanted to go tankless, so after many hours of research and finding reputable local plumbers in my area, I reached out to the Water Heater Company to analyze my current situation and come up with a replacement solution. Again, my goal was to go tankless; however, after Tanner from The Water Heather company surveyed my property and went over all my options, it was determined the configuration of my main gas line and proper placement of the unit would not be conducive to install a tankless unit as there were many obstacles, hours of labor, and resorting back to a tank heater would be the best option for me. Tanner suggested I go with a company called Bradford White, which has fantastic reviews and a unit that will give me some longevity. I decided to have Tanner install the unit, which included all-new copper fittings and much more. This company knows water heaters, and I appreciate his honesty that he could install a tankless heater, but financially, the layout of my house would not be in my best interest. Therefore, I felt comfortable working with The Water Heater Company to install my new Bradford White gas tank water heater. Tanner was highly professional, cleaned up after the job, and went through everything he did installing my new tank. I highly recommend anybody looking for a tankless or tank water heater contact the Water Heater Company, and if youâ re lucky enough, Tanner will be your technician."

"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."

"They responded the same day to my request. Ryan explained the options well. Two men were here for several hours and they even called the gas company to get more information on the incomplete combustion issue that the gas company found."

"Replaced water heater supply pipe, using compatible materials--previous installer had used different materials that resulted in electrolytic corrosion. Service was reasonably prompt and courteous, explanations clear and enlightening. Pilot light went out after service, repairman came back to relight, and explain how to relight."
