Best water heater pros near Killian, LA

Q: How long does it take to install or replace a water heater?

• <div><p>The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.</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: What is the proper vent pipe for a water heater?

• <div><p>Due to the high temperature, using stainless steel vent pipes for your tankless water heater&rsquo;s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.</p></div>

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: Are hot water heater expansion tanks required for warranty coverage?

• <div><p>Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It&rsquo;s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn&rsquo;t required for the warranty, it&rsquo;s usually mandated by building codes&mdash;although not for <a href="https://www.angi.com/articles/how-much-does-tankless-water-heater-cost.htm">tankless water heaters</a>.</p></div>
