"My prior water heater, a 50-gallon tank, started leaking after 15 years. I called Streamline to confirm that it needed replacement, and to replace it. I was considering a tankless water heater already, and the first tech walked me through the pros and cons, then wrote up an estimate. Two additional techs came the next day to install the heater and the necessary gas and power lines. The only issue I had was that one of the newly installed gas fittings leaked gas into the basement. I shut off the supply valve and called Streamline, and they came out within half an hour to fix it at their expense. Mistakes happen, and I was impressed with how professionally they corrected that one."

"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!"

"My repairman was great, he was upfront he noticed a few things that were in need of repair. I decided not to go with the gas line because it wasn't budget friendly but did get my water heater flushed and my line fixed."

Water Heaters FAQs, answered by experts

Traditional gas or electric water heaters last an average of six to 11 years. However, with excellent maintenance, they can last up to 15 years. Heat pump water heaters, on the other hand, last an average of between 12 and 15 years and potentially longer with proper maintenance. In both cases, your home's water quality can be a determining factor regarding the lifespan of your water heater.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

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.

Homeowners insurance may cover the repair or replacement of a water heater if it's damaged by a covered peril, such as a fire or a burst pipe. However, policies typically do not cover repairs or replacement needed due to normal wear and tear, old age, or lack of maintenance. For these issues, a home warranty or a manufacturer's warranty may provide coverage. While the policy might not pay to fix or replace the malfunctioning appliance itself, it often covers the cost of water damage restoration caused by the faulty water heater. Always check with your insurance provider to understand the specifics of your policy.
