"Removed old hot water tank and replaced it with a tankless hot water heater. Work was done in crawl space with less than six feet height available in work area. All done in a few hours last September. It's now the following August (11 months or so later). Everything seems to be working okay. Workmen were polite, professional, timely, focused on the job, carried away all the old parts and cleaned up well---we were quite pleased with the whole process."

"I had Cape Fear come out for a second opinion because the company my home warranty company sent out was a joke (Comfort Wizards by the way). It was night and day difference with Cape Fear. Eddie(?) truly checked every part of the A/C unit, both in the attic and outside. He was very nice and patient with me watching and asking questions. I eventually decided to just get a new heater and A/C unit and got 5 or 6 different quotes. Cape Fear was tied for the lowest price. I normally go with the middle price quotes, but I was so impressed with the inspection and service provided by Cape Fear that I decided to go with them. The two men that replaced my unit were pretty young, which worried me a little, but it's been 3 weeks and I'm very happy with how everything is running so far."

"Outstanding Service from Modern Plumbing LLC! I had an excellent experience with Modern Plumbing LLC when they installed my new water heater. From start to finish, the service was professional, efficient, and stress-free. The plumber arrived on time, clearly explained my options, and walked me through the entire installation process so I knew exactly what to expect. The installation was done quickly and cleanly, with great attention to detail. Everything works perfectly, and I can already tell the quality of work is top-notch. It’s rare to find a plumbing company that combines expertise, honesty, and great customer service, but Modern Plumbing LLC absolutely delivers. I highly recommend them to anyone needing reliable plumbing or water heater installation—you won’t be disappointed!"

"Chris and his assistant today, Robert, were professional, courteous, and honest. I scheduled them to change out water supply lines on 5 toilets in our new home. Chris assured me that the lines installed were of high quality and did not need to be changed out. I have plans to install a water monitoring system and will definitely use Cape Fear (requesting Chris, of course) for the job. I highly recommend Chris and by association, Cape Fear!"

"I called in the morning and Chris came out in the afternoon, when I was available. He explained and showed me what the problem was. He didn't have a new water heater on his truck so Tim came about 45 mins. to bring one. Installation was fast and Chris was very professional. They will be the first ones I call if I have any other issues."

"Good work replacing furnace, hvac and ductwork. Did not complete job in the time frame promised, but did bring heaters over and provide a gift card to a steakhouse for the inconvenience. I have found them difficult to reach to schedule included service that was included with my purchase."

Water Heaters FAQs, answered by experts

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget. 

Pros

  • Safer than gas or propane

  • Doesn’t require extensive venting systems

  • Lower upfront costs

  • Simpler to operate

  • No pilot light

  • Easier installation

  • More efficient heating than gas models

  • Available as point-of-use (POU) and whole-house units

Cons

  • Slower to heat water

  • Longer recovery time

  • Possibly higher operating costs

  • Doesn’t work during a power outage

  • Costs can increase without a 240-volt connection

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.

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.
