"Andy and his helper were INCREDIBLY respectful, punctual, and competent. Andy showed me what was wrong with my leaking shower head before/after repair and stepped me through the whole process. The total cost was cheaper compared to other plumbers and he took the time to show me how I could prevent other water damage in my shower stall. He made sure everything was cleaned up afterwards. More importantly, he was very nice and easy to work with. I highly recommend his services for any plumbing repairs."

"I sent an inquiry through Home Advisor the night my water heater started leaking and Bob called me bright and early the very next morning. He was professional, pleasant and replacement pricing was very reasonable. He and his plumber treated my home with respect by putting down drop cloths and they were quick with the replacement! They now have a customer for life."

Water Heaters FAQs, answered by experts

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.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

An average-sized empty water heater weighs around 150 pounds. Tankless water heaters are much lighter, weighing between 10 and 50 pounds. The smaller size and added convenience come at a price, though—tankless water heaters average about twice the price of their traditional counterparts.

Choosing between an electric water heater vs. a gas water heater comes down to personal preference. Overall, electric heaters are more energy efficient than their gas competitors. They’re also quieter to operate, take up less room, and don’t come with a risk of gas leaks. 

The downside is that electric water heaters cost more to operate than gas. They might also struggle to heat water fast enough for households that use large amounts of hot water. Lastly, a power outage could cause your electric water heater to stop working, whereas gas water heaters may still function.

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.
