"Rich came out to replace our sludge-filled, overheating, failing old water heater. It was a difficult situation and he took the time and had the patience to do the job right. The fee was under the national average, reasonable. The water heater is located in a closet off the master bath and at first it would not drain. Rich knew just what to do. Took his time to get old one out and did not mess up our house. Cleaned up behind himself and left us with a larger water heater (as requested) and worked out how to fit it into our small location. Replaced all the plumbing to the water heater and now we have a better made, self-cleaning, more efficient electric water heater to provide us with lots of clean hot water."

"From the first meeting with Matt when he gave us a timeline and our estimate, through the install and the walk through of finished work, it was all very well done. The installers were very polite and made sure that any flooring that they would be walking on or bringing out the old water heater on were completely covered to protect from any dirt or water. Any time we went to see if they needed anything they would tell us what they had gotten done and what they were working on. Not once were they short or put out as some people are when you are curious about what is going on in your house. I would use Lighthouse any time and have already told our friends how professional and caring they were about everything that went into our home and the proper working of it all before they left. They also did not take the last half of our payment until the final walk through which was 5 days after all work was completed. They also do military discounts and cash/check discounts which is a lovely perk."

"Installer came unprepared to to fix fire caulk he damaged as well as not having a lift device to get the water heater onto it's stand. Had to go buy fire caulk at my expense and find a board for him to slide new water heater up to get it on the heater stand."

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.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

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.

An average-sized empty water heater weighs around 150 pounds. Tankless water heaters are much lighter, weighing between 10 and 50 pounds. The smaller size and added convenience come at a price, though—tankless water heaters average about twice the price of their traditional counterparts.

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions.
