"What I liked about water heater plus is that the person I contacted clearly explained all of the options to me. He did not try to convince me to take any route in particular; he encouraged me to do what would be best for me financially at the time. I ended up replacing my old water heater and I think that was the best decision. The technician efficiently replaced my old water heater."

Customers say: Super punctual

"They were punctual and it was determined that I need a new water heater. I have a limited space requirement. They did some research and called me back two days later with a price. I have not made a decision and have not contacted any other plumbers as of this moment."

"Really appreciate the great service we received from Logan, from the sales consultant to the installation. Everyone was very respectful and did a great job working with us. We are also very impress with the HVAC sold to us, this house has never been this cool in the summer, even the upstairs is very comfortable. Sometimes we have to turn the thermostat up a degree or two where we are too cold. The old unit never did that. Received all our warranty paperwork in a timely manner. Very great service."

"The plumber came out and replaced the valves in a neat and speedy manner. He inspected his work and found that one valve had a slight leak so he fixed it without adding time to the invoice. He even gave me a tip on how to drain my hot water heater while we waited for the pipes to drain."

Water Heaters FAQs, answered by experts

Flushing biannually, checking the anode rod, and temperature settings maximize equipment lifespan while reducing surprise costs.

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.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

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.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.
