"Mr. Floros worked with my schedule on a short timeline to replace our water heater. He professionally negotiated with me about how to get the job done approximately the way that I wanted while still meeting local code. When the job was completed, he cleaned up and took away the old unit. The price was a great value considering the work done."

"What a great guy! The furnace and the water heater went out at the same time. I was freezing! It was all sorted out the same day. Angel was able to remove my old water heater with a new one. I plan on hiring him again, Thanks, youâ re an Angel!"

"We have been loyal customers of Genove for years, but this year they exceeded any expectations. From the emergency service call on a cold Sunday night in February to the installation of the new furnace and hot water heater today. Armando and crew are terrific. Ryan, Richie and Shawn completed the project in less time than we expected. And, Armando assisted us in the HEAT loan program which has us paying for this work at zero interest over 7 years as well as handled the rebate programs. Highly recommend Genove!"

"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

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.

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.

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.

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.

The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of time it takes to drain a water heater averages from 10 to 30 minutes.
