Customers say: Quality work

"Mark from Water Heater Medic did an outstanding job. From the first phone call to determine the price to setting up my appointment to the actual installation, everything was terrific. After determinating that my water heater replacement/installation in the basement would not be a complicated one (e.g., no stairs, no tight spaces), he gave me a bit of a discount. The final price he quoted me was lower than everyone else. (I would say much lower because I don't want to give the impression that his price was suspiciously cheap in exchange for shoddy work. his work was in fact excellent and an outstanding value.) Setting the appointment was quick and painless. Mark worked around my busy schedule, which I very much appreciated. During the installation, Mark kept me informed of what he was doing. The whole process only took about an hour and he left my home just as clean as it was before he arrived. I will use Water Heater Medic for all of my future water heater needs and would definitely recommend them."

"Bruce and Bill of Williams and Associates Mechanical Contracting recently removed and replaced my 18 year old oil fired boiler and added an indirect fired water heater. I had been saving for this project for over a year and had been geeking out in my avid research (Thanks Internet!) of products available, reviews and costs, as well as the reputation and reliability of local heating and plumbing contractors. I knew what I wanted, I just needed to stay within my budget and find a contractor I could trust. It is therefore, my pleasure to let others know, on the same web review sites that I referred to, how overwhelming pleased I am to have worked with Bruce Williams and his team. They skillfully removed and installed the heating system in a day, took pride in their work and took the time to explain the new system and to fully answer all my questions. Bruce and Bill clearly like what they do for a living, have great people skills and work very well together. I was able to get the very best of products and still come well under budget. I cannot thank these guys enough! Honest, Professional and Reliable! My dusty, unfinished basement with my new Viessmann boiler, Carlin burner and HTP indirect fired water heater is now my favorite part of the house!"

"Called the original installers from 12 years ago but they weren’t very responsive. Ray Page responded with same day service and worked with my schedule. They sent text alerts with picture of Scott. Scott has been to my house before to fix Kitchen faucet and garbage disposal. Very professional and nice. This time, he did the big job, replaced the water heater and cleaned up as well. Very reliable service."

"I needed an emergency replacement of a hot water heater. Daniel not only came earlier than he was supposed to, he was very informative, polite, and very thorough. He went above and beyond to do the job, snd clean up. Whoever answered the phone when I called this am, squeezed in my appointment, and never did I have to speak to a machine. They texted me when he was on the way, snd showed exactly when he was supposed to. Great friendly customer service- will definitely recommend them to others and use them again! Oh, and the guy that brought him the new heater, came quickly with it and was equally friendly and knowledgeable! Ray Page- Thank you all so very much!"

"Woke up to a flash flood in my basement that never floods. Technician got to my place within an hour of calling and had a new sump pump installed by early afternoon and the water drained out. It was stressful - the water was coming up fast and they dealt with it quickly. The lead technician was professional and courteous."

Got it done in a timely manner so residents would not be down all day and could turn the water back on quickly.Would highly recommended to anyone with all plumbing repairs."

Water Heaters questions, answered by experts

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

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.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.

Several signs indicate your water heater may be failing or in need of replacement. Key indicators include:

  • Age: A water heater older than ten years is approaching the end of its typical lifespan.

  • Water Quality: If you notice rusty or discolored water from your hot water faucets, or a foul odor similar to rotten eggs or sulfur, it can signal internal corrosion.

  • Unusual Noises: Banging, rumbling, or popping sounds from the tank often mean sediment has built up, causing the unit to overheat.

  • Leaks: Any water pooling around the base of the tank or visible leaks are clear signs of failure.

  • Performance Issues: A decline in performance, such as water not getting hot enough, taking longer to heat up, low water pressure, or decreased efficiency, suggests the unit is struggling.

  • Visible Damage: Obvious rust and corrosion on the exterior of the tank can indicate a more serious internal problem.

While these signs often point to replacement, some issues may be fixable. It's best to consult a professional plumber to diagnose the problem before investing in a new unit.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.
