"Mr. Aquino was so incredibly helpful. We were on a tight timeline and he was able to come out the same day and do the plumbing repair to our bathtub we needed even though it ended up being a bigger job than originally thought. He explained everything as he was doing it fantastic Customerservice really knows his stuff and a great value for the price highly recommend them."

"We could not be happier with our new bathroom, thanks to McCormick! Khaled was knowledgeable and really took the time to understand our style preferences. The whole team was great about keeping the workspace tidy, which we appreciated. Now, we have a bathroom that feels luxurious and welcoming. Highly satisfied with their work!"

"I called Water Heaters Only out of desperation on Sunday...Seth @ toll free # was fully aware of our tenants being without hot water for 2 days and was able to get a technician out on Monday morning. Monday @ 5 pm, hot water was up and running. David, the technician knew what had to be done to get the heater up and running. The next day, we did have a hiccup with a part but David came out immediately and tweaked the part -- all is good. Here is what I like -- 1. no sales pitch. 2. David gave me a plan b for possible additional work. 3. this company is available 365 days and you dont have to wait for parts to be delivered from out of state. 4. Water Heaters Only has their own facility for parts."

Water Heaters FAQs, answered by experts

Going from a tank to a tankless water heater is one of the most effective ways to lower your utility bills. The switch also frees up more space and ensures a consistent hot water supply, as the water is heated on an as-needed basis. It costs between $5,400 and $7,400 to install a new tankless water heater. Most installation companies will also help dispose of your old water tank.

In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.
