Q: What size breaker does a hot water heater need?

• <div><p>When wondering <a href="https://www.angi.com/articles/what-size-breaker-for-water-heater.htm">what size of breaker for a water heater</a> is appropriate, the majority of hot water heaters need a 30-amp, two-pole breaker. Most residential water heaters use 240 volts and between 3,500 and 5,500 watts. If your appliance matches these measurements, a 30-amp breaker is likely perfect. Owners of point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts often find that a 30-amp breaker is adequate. Water heaters that use more watts than average may need a 40-amp breaker. Smaller units that use fewer watts could potentially use a 20-amp breaker.</p></div>

Q: Is it hard to replace an electric water heater?

• <div><p>Unless you have previous plumbing experience or extensive experience with water heaters, <a href="https://www.angi.com/articles/can-install-water-yourself.htm">you should avoid replacing your electric water heater yourself</a>. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.</p></div>

Q: Do I need to replace my water heater?

• <div><p>Whether to repair or replace your water heater is determined by your water heater&rsquo;s age and condition. If you have an older model reaching the end of its life expectancy or if your water heater has been having problems more frequently than usual, replacement might serve you better. If you&rsquo;ve been thinking about <a href="https://www.angi.com/articles/is-a-tankless-water-heater-worth-it.htm">upgrading to a tankless water heater</a>, then you may not want to spend any further on repairing your old one, either.</p></div>

Q: Should I get a tankless water heater?

• <div><p>Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. <a href="https://www.angi.com/articles/is-a-tankless-water-heater-worth-it.htm">Is a tankless water heater worth it</a>?
