"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."

"Wesley was fantastic! We were hoping to be able to extend the gas line from the fireplace to the stove but the piping was too small there to accommodate the stove we purchased. While he said it could be done, and was significantly less expensive, it may not be able to provide the 'power' the stove required. We chose to do it the right way, not the 'cheap' way, pricing was still reasonable for the amount of work that needed to be done. Highly recommended!!"

Water Heaters questions, answered by experts

While possible, professional assistance is recommended to ensure compliance with local regulations and avoidance of avoidable risks.

Gas water heaters last between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don’t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit. 

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

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.

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.
