How often should electric water heaters be replaced?

• <div><p>Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.</p></div>

Q: What do I need to replace after water damage?

• <div><p>Any item that can hold on to moisture and encourage mold growth should be discarded and replaced following water damage. Upholstered items, such as armchairs and couches, and soft items, such as mattresses, usually must be thrown away once they've taken on a lot of water. Soft furniture is difficult to dry out, creating an inviting environment for mold.</p><p>You may also need to replace hardwood furniture following water damage if you're unable to fully dry it out. If you have appliances and electronics that have been fully submerged in water, particularly sewage, you'll need to replace those, too.</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>

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: Can you vent a water heater outside the house?

• <div><p>Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.</p></div>
