"I had a water heater emergency on a Saturday, and my four girls were frantic with no hot water.  I called several plumbers who were not able to come out on the weekend or wanted way too much money.  When I called Steve at All about Plumbing, he was very nice and was able to come out the sameday.  He did not charge an estimate fee, gave me an estimate to fix the problem.  He installed a new heater that night and we were back in business and ready for Sunday morning showers before church.  He promised to be there at a certain time and was.  He was professional.  I would recommend to my friends and family."

Water Heaters questions, answered by experts

The amount of time it takes to replace an electric water heater will depend on the skill level of the individual who is replacing it. For example, if you replace it yourself–and you don’t have much experience–you can expect the project to take a full day. 

However, if you have a certified plumber or water heater contractor install your new water heater, it can take as little as 2 to 3 hours.

Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.

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.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.

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.
