"Dennis installed a new 75 gallon water heater and circulation pump in our home. His price was very competitive and lower than several other bids we got. He communicated with us well throughout the entire process. He worked around our schedule and the installation took only a couple of hours. The new water heater is working perfectly. I highly recommend Dennis and USA Water Heaters."

"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."

"⭐⭐⭐⭐⭐ Water Heater SOS was a lifesaver! When our water heater broke down, they responded quickly, diagnosed the issue, and had it fixed the same day. The technician was professional, knowledgeable, and took the time to explain everything clearly. Pricing was fair, and the service was top-notch. I highly recommend Water Heater SOS for anyone needing fast, reliable water heater repairs!"

"Would highly recommend Drain Town Rooter to anyone. May be a funky company name but they did a great job on my Tankless water heater install. Ryan was excellent and even came back after I removed the old tank box/stand, had some drywall repair and painting done, to re-route the pressure relief pipe straight down which had been routed around the old tank box. Cosmetic but much cleaner looking. I’d hire them for other plumbing jobs as well."

"I did my leg work on the re-pipe of my house and the remodel for my bathroom. I met with 5 different plumbing companies. Mike and Bonnie gave us the best price and the team did great work. They went above and beyond, not only re-piping my 1927 house, replacing my 30 year old water heater, and doing the plumbing for my bathroom remodel, but also referring us to a great father son team who gutted and did all the remodeling for my bathroom. Additionally, I had a minor plumbing issue today, that had nothing to do with the work they did, and Bonnie, via text, walked me through doing my own repair. You really can't find that kind of service elsewhere!"

Water Heaters questions, answered by experts

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

Not all types of water heaters require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation.

If your water heater continues to have issues, you may wonder how long an electric water heat lasts. On average, these units last between 10 to 15 years. Following a proper maintenance schedule can help the water heater live to the end of its average lifespan or longer.

Homeowners insurance may cover the repair or replacement of a water heater if it's damaged by a covered peril, such as a fire or a burst pipe. However, policies typically do not cover repairs or replacement needed due to normal wear and tear, old age, or lack of maintenance. For these issues, a home warranty or a manufacturer's warranty may provide coverage. While the policy might not pay to fix or replace the malfunctioning appliance itself, it often covers the cost of water damage restoration caused by the faulty water heater. Always check with your insurance provider to understand the specifics of your policy.

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.
