"Wanda?s is awesome! My old electric hot water heater tank finally retired to the recycling bin. I called on Tuesday evening and spoke to a knowledgeable technician named Chad. I told him what my old unit was doing and he said it definitely needs a replacement after 17 years. He then asked how the home is heated. And then gave me the 2 options for my home. He patiently explained the differences between the hybrid heat pump unit vs the electric one that was presently on its way out. He answered all my newbie questions. He explained the pricing between the two units. I told him I have to discuss everything with the cfo and I would call back Wednesday morning. He also told me they would get me on the schedule for tomorrow or the next day. That was amazing. I called the next day and spoke with Amanda to schedule me in the following day. Chad showed up the following morning and did an awesome job. He was very polite and knew his job well. I am very satisfied so far with Wanda?s."

"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

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.

The good news is that most home warranty plans cover hot water heaters, regardless of whether you have a tank or a tankless model. Your hot water heater should be covered by your home warranty because it's considered an essential home appliance.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.

Going from a tank to a tankless water heater is one of the most effective ways to lower your utility bills. The switch also frees up more space and ensures a consistent hot water supply, as the water is heated on an as-needed basis. It costs between $5,400 and $7,400 to install a new tankless water heater. Most installation companies will also help dispose of your old water tank.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.
