Q: Are water heater thermocouples universal?

• <div><p>A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.</p></div>

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: Are hot water heater expansion tanks necessary?

• <div><p>While many older homes don&rsquo;t need hot water heater expansion tanks, they&rsquo;re necessary in most newer homes and are required by building codes. These tanks are required by code in areas where there are backflow preventers or pressure regulators on the incoming water pipe between the public water pipes and the water heater. However, tankless water heaters don&rsquo;t require expansion tanks.</p></div>

Q: Is it better to vent a gas water heater out of the wall or roof?

• <div><p>Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you&rsquo;re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.</p></div>
