How much does water expand in a water heater?

• <div><p>Water expands when heated and also when freezing. When water is heated, it expands by around 4%.

Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed. </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: Can you ask a pro what’s the best breaker size for your water heater?

• <div><p>If you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won&rsquo;t overload, which could lead to fire and other damage.</p></div>

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: What size tankless water heater to replace a 50-gallon water heater?

• <div><p>A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater. </p></div>

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet. I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."
