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>

Q: Can I use multiple tankless water heaters?

• <div><p>You can use multiple tankless water heaters, but that doesn&rsquo;t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you&rsquo;re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations. </p></div>

Q: Are hot water heater expansion tanks required for warranty coverage?

• <div><p>Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It&rsquo;s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn&rsquo;t required for the warranty, it&rsquo;s usually mandated by building codes&mdash;although not for <a href="https://www.angi.com/articles/how-much-does-tankless-water-heater-cost.htm">tankless water heaters</a>.</p></div>

Q: How often should you replace an anode rod?

• <div><p>Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. </p></div>

Water Heaters questions, answered by experts

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.

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–and to ensure it runs as efficiently as possible.

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener.
