Q: Are new water heaters better than old ones?

• <div><p>Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. </p><p>If you&rsquo;re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.</p></div>

Q: What is the life expectancy of a hot water recirculating pump?

• <div><p>A well-maintained hot water recirculating pump can last 5 to 15 years. Pumps that run continuously may have a shorter lifespan than demand-controlled models. Hard water can reduce longevity by causing mineral buildup in the pump and pipes. Regular maintenance, such as cleaning or replacing filters, can extend the pump&rsquo;s lifespan.</p></div>

Q: Are hot water heater expansion tanks necessary or required by code?

• <div><p>While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.</p></div>

Q: How can I cut down my water bill?

• <div><p>A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill. </p></div>
