Q: Will a larger water heater require a larger circuit breaker?

• <div><p>A <a href="https://www.angi.com/articles/what-size-breaker-for-water-heater.htm">larger heater requires a larger breaker</a>&mdash;unless there&rsquo;s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a <a href="https://www.angi.com/nearme/electrical/">local electrical pro</a>. </p></div>

Q: How long will a water heater last after it starts leaking?

• <div><p>A leaking water heater could potentially last for a few weeks or months before you need to repair it. However, it's not advisable to wait too long. Once your water heater starts leaking, it's likely that the underlying cause of the leak is getting worse as time goes on. Without immediate repair, your water heater could fail. Instead of using a leaky water heater, you should turn it off and call a pro to fix it.</p></div>

Q: How long do gas water heaters last?

• <div><p><a href="https://www.angi.com/articles/how-long-does-gas-water-heater-last.htm">Gas water heaters last</a> between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don&rsquo;t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit. </p></div>

Q: Can you install an expansion tank anywhere?

• <div><p>No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There&rsquo;s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for. </p></div>

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>
