Are tankless water heaters more energy-efficient than traditional water heaters?

• <div><p>According to the <a href="https://www.energy.gov/energysaver/tankless-or-demand-type-water-heaters">U.S. Department of Energy</a>, tankless water heaters are anywhere from 8% to 34% more efficient than regular water heaters. Exactly how much energy you’ll save depends on your household’s water usage. When you purchase a tankless water heater, you’ll also likely upgrade to more efficient technology than your current water heater, which can add to energy savings.</p></div>

Does the age of your water heater affect home insurance?

• <div><p>Your water heater's age can affect your homeowners' insurance policy. Many policies will ask how old the heater is when you first apply for a policy—and they may make you replace a model that's over 10 years old. </p><p>Even if your policy permits you to have an older heater, it may significantly reduce the amount of protection available. If an older water heater suddenly leaks and causes damage to parts of your home, your policy may not cover it.</p></div>

Do both my boiler and water heater need their own expansion tank?

• <div><p>Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater. </p></div>

Q: How do you know when your electric hot water heater is going out?

• <div><p>Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.</p></div>

Q: How big should a hot water heater expansion tank be?

• <div><p>The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.</p></div>
