"TopTec responded immediately, scheduled the appointment for 8AM the next business day. Jason the plumber arrived early, concisely explained his planned actions, coordinated with other trades, professionally executed the installation of the tankless heater with minimal disruptions, cleaned up and left a happy customer. Toptec did an excellent job, for my next plumbing issue I will call Jason at Toptec."

"Carlos is excellent. He is very responsive, professional & reasonably priced. He & Eli installed a new water heater very quickly for us after our old one started leaking. I highly recommend CAB Backflow and would absolutely use them again for other plumbing jobs."

"I was very pleased with all the work Joe did at my Mom's house and mine in Cary. At my Mom's he put in a new utility sink and repaired it and also repaired a significant leak downline from a toilet. When I saw the quality of his work I hired him to work at my house. There he removed and replaced a hot water heater and repaired a big leak in my utility sink and replaced the faucet. With the water heater he had to remove the black pipe to remove the heater then repipe after. After he was done both houses were cleaner in the areas he worked . I would hire him again if I need any plumbing done in the future."

Water Heaters FAQs, answered by experts

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.

Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.

On average, a tankless water heater should last between 10 and 15 years. Its lifespan will be affected by how much it's used, the effect of weather where your home is on the unit—colder is harsher and will shorten lifespan—and if the heater is maintained appropriately and regularly. There are many signs your water heater needs to be replaced, so pay attention to anything that changes with your heater or hot water.

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’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.

A larger heater requires a larger breaker—unless there’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 local electrical pro.
