How often should electric water heaters be replaced?

• <div><p>Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.</p></div>

How much does water expand in a water heater?

• <div><p>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. </p></div>

Q: How long does it take to install or replace a water heater?

• <div><p>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.</p></div>

Q: What’s wrong with high water pressure?

• <div><p>Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it&rsquo;s actually a silent threat to plumbing. </p></div>

Q: Does an electric water heater need its own circuit breaker?

• <div><p>A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.</p><p>Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code&ndash;and to ensure it runs as efficiently as possible.</p></div>

He never returned my call after I had already told him I was interested in having him do the work. I waited until 2 more days before contacting Sheaffer's Mechanical to replace my water heater. I would still consider AJB in the future for other work needing done.

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet. I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."
