"I had my full home repiped as I switched from electric to forced hot water heating. Fred was courteous, communicative, and timely in making the repairs. We ran into quite a few snafus and he took them in stride. His quote was MUCH lower (about half the price) of the original quote we got. Definitely recommend."

"I was impressed with his knowledge and his ability to explain his thoughts to me as we were reviewing what needed to be done to install a replacement propane water heater He scheduled the project right away and came in the time frame designated, finish the work and also did extra functions that had to be done to allow the equipment to get into my basement. He followed up to make sure everything was working well and offered to come back in a day or two if I needed assistance. His billing was easy and professional. We are hoping to have him back again next year to do some HVAC work."

"Woke up to no heat. Called Alan at 7:00 am. He came by with some electric heat at 8:00am to hold us over to when he could come back after he finished another no heat call at other property. He was back at 10:00 am to start on our problem. We had a clogged nozzle. He changed that and the filter on the oil tank and we had heat by 11:00 am. Alan left area very clean and no left behind trash. Total cost $91.00"

"This is the second time I have used NE Renovations.    On a Saturday morning I discovered I had no heat, my heater would not come on.  I contacted the individual I had used in the past and was told they could not come out for a few days.  I sent an e-mail to Richard, the owner and he contacted me almost immediately.  He told me he could come out the same day to see what the problem was.

He showed up on Saturday on time as scheduled.  Unfortunately, the part I needed had to be ordered and he told me he would be over first thing Monday morning.  Sure enough he arrived at 8:00 am and his employee, Jimmy arrived shortly after.  It turned out additional parts had to be ordered.  Richard kept me informed of the progress all along.  After the parts were obtained, the heat was fixed and works great.

I also would like to mention how professional and courteous Richard always is.  And it is great to have someone so reliable to depend on.  I would not hesitate to use NE Renovations again. "

Water Heaters questions, answered by experts

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. 

Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. Is a tankless water heater worth it? Most homeowners will save money with a tankless unit in the long run by using less energy.

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. 

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.

It’s important to find the type of water heater that fits your needs and budget. Depending on the type of water heater, size, brand, and the type of energy you use to heat the water, costs range from a few hundred dollars to several thousand. Some of the most common types of water heaters include:

  • Electric: $600–3,500

  • Gas: $700–$2,700

  • Propane: $700–$2,500

  • High efficiency: $1,500–$3,000

  • Indirect: $1,200–$3,500

  • Hybrid heat pump: $1,200–$3,500
