Can you switch to a tankless water heater from a heater with a tank?

• <div><p>Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.</p></div>

Q: Can I use multiple tankless water heaters?

• <div><p>You can use multiple tankless water heaters, but that doesn&rsquo;t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you&rsquo;re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations. </p></div>

Q: What is involved in converting a gas water heater to an electric one and how much does it cost?

• <div><p>Yes, you can convert a gas water heater to an electric one, but it is a complex process. You will need to ensure there is adequate power for the new electric unit, as they require more power than gas models. The project also involves safely closing off the gas lines and ventilation, and some cities may require a permit for the conversion. The cost can range from $1,500 to $4,100, depending on the installation scope, plumbing and electrical work, and the water heater model. For an accurate quote, it's best to contact a local professional. Also, be aware that your monthly utility bills may increase after the conversion, as natural gas is typically cheaper than electricity.</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: 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>

This was a big job. It took them several months to get the crews out to do the work, but once they started, it all moved very quickly. They had to do some extra work because of water damage discovered when they removed the old siding, but the charge for repairs was lower than expected.
