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>

Can a water heater element be replaced without draining the tank?

• <div><p>No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing. </p></div>

Q: What are some common issues with a water heater?

• <div><p>Often, the first issue you might encounter is a lack or loss of power&mdash;this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion. </p></div>

Q: Which types of gas appliances might require installation or replacement services?

• <div><p>Examples include gas stoves, ovens, and water heaters. Confirm with your provider for specific items.</p></div>

Q: Do water heater installers need to be licensed?

• <div><p>In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our <a href="https://www.angi.com/angi-license-check.htm">state licensing tool</a> to find out if a contractor you&rsquo;re considering in your area holds a plumber&rsquo;s license.</p></div>

"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."
