Can I switch from a gas water heater to electric or vice versa?

• <div><p>When replacing an old unit, you might want to switch from a <a href="https://www.angi.com/articles/gas-vs-electric-water-heaters.htm">gas water heater to an electric water heater</a> or vice versa. To do this, you will likely need to add infrastructure to the area. For example, you likely don’t have a gas line that served your old electric water heater. You’d have to call a plumber to put in a new gas line. If you’re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line. You will then need an electrician to add wiring for the new electric unit.</p></div>

Q: Are electric water heater venting and installation requirements the same from state to state?

• <div><p>No state requires you to vent an electric water heater. Other installation requirements for water heaters will vary, though, depending on the state and local jurisdiction in which you live. Some places require permits, while others don&rsquo;t. Some may force you to place the appliance a certain distance from any walls or other appliances, while others don't. When you find a <a href="https://www.angi.com/articles/who-can-install-water-heater.htm">local professional to install a water heater</a>, this expert will ensure you follow all the local regulations. </p></div>

Q: Can I run a 30-amp water heater on a 40-amp breaker?

• <div><p>Yes, this would be an appropriate choice. In order to comply with the National Electric Code&rsquo;s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current <a href="https://www.angi.com/articles/water-heater-keeps-tripping-breaker.htm">water heater keeps tripping the breaker</a>, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.</p></div>

Q: Does installing a water heater yourself void the warranty?

• <div><p>Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. </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."
