Q: 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&rsquo;t have a gas line that served your old electric water heater. You&rsquo;d have to call a plumber to put in a new gas line. If you&rsquo;re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line.

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.
