"Donald Rogerson responded very quickly, analyzed the photos I sent him, knew exactly what to bring, and provided a very reasonable quote over the phone. He reassured me from the start, and took control of the situation with the utmost professionalism and clear communication. His work was impeccable, and he even insisted on cleaning up. I heartily recommend him, not only for water heater issues, but for any indoor plumbing need. He will certainly be my plumber from now on."

"Cool Air Mechanical replaced two heaters and AC units in my house that were old and end of life. I have to say one major thing about this company: They are fully professional. 1. They show up on time. 2. They accepted a last-minute request that made the installation superb. 3. They were meticulous on all details. 4. Everything was as clean as when they came in. 5. They were all so very polite and accommodating with any question I had. 6. It is a fully competent staff that, after looking at a job they completed, leaves it looking better than when they started. Of all the contractors that I have had in the past 10 years, they are the only one that has surpassed my expectations. Great job by Elio, Moises, Jean P., Berny and Morris. You guys are the greatest!"

"I had a water leak in my front yard & after researching the highest rated Plumbers, I found Rooter Pro Plumbing of Georgia. They had great ratings on Trust Dale Caldwell, Angi's List, & Google. I scheduled a visit with them & Jerimey Jackson came by & did a leak detection. It was determined that I had multiple leads in my water line and he gave me all of my options & pricing. He is an expert on everything to do with plumbing & a great guy too. My water heater is 23 years old, so I decided to replace that as well. Jerimey led the work crew the next day in replacing my water line & water heater replacement. All the work was complete that day & the results are very good! I am very pleased with Rooter Pro Plumbing and the work they performed & the people I dealt with. Even the people in the office were great! I will use them again & recommend them to my friends & family! Paul Taylor"

"AC Plumbing Solutions does Awesome Work! Very HONEST, professional, and informative from start to finish. I contacted AC Plumbing after I had a water heater installed by another plumbing company. The prior company (nonstop plumbing) left the gas value open and did not adjust the pressure, so my pipes were making a bunch of noise. We tried to get nonstop plumbing to come back, but they stop answering the phone. My husband managed to stop the gas leak, but we needed someone to come out and fix the knocking noise. That is when we called AC Plumbing Solutions, LLC. They came out quickly and knew exactly what they were doing. Mr. Clayton fixed the problem, was in an out in a short period of time and it did not cost me a fortune. I highly recommend AC Plumbing Solutions, LLC for all your plumbing needs. I will never use another company again."

Water Heaters FAQs, answered by experts

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.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.

Your water heater's age can affect your homeowners' insurance policy. Many policies will ask how old the heater is when you first apply for a policy—and they may make you replace a model that's over 10 years old. 

Even if your policy permits you to have an older heater, it may significantly reduce the amount of protection available. If an older water heater suddenly leaks and causes damage to parts of your home, your policy may not cover it.

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.
