"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 FAQs, 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.

There are many issues that can cause cold showers, but the most likely is a problem with your water heater, especially if other fixtures also don’t get hot water. If it’s just your shower not getting hot water, you likely have a broken or damaged shower cartridge. You can replace this yourself or hire a plumber to do the work for you if you’re not comfortable working with plumbing.

Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.

If you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won’t overload, which could lead to fire and other damage.
