What Is a Tankless Water Heater?
Unlike a traditional unit, a tankless water heater doesn’t heat water until you are ready to use it. That’s why there is no tank for storage.
Instead, water is heated instantly when you turn on your faucet by running water through an electric heat exchanger and into your pipes. The result is on-demand hot water for showers, laundry, dishes, and more.

Tankless Water Heater Installation & Replacement
There are many benefits to installing a new tankless water heater. These units are much more energy-efficient than a traditional heater as they sit idle when hot water is not in use. This significantly reduces your electrical bill and saves you money.
In addition, these systems can last for 20 years, while traditional water heaters only last for eight to 12 years. A tankless water heater will also free up space because it’s wall-mounted and is significantly smaller.
At Larry & Sons, our plumbers are here to handle your tankless water heater installation or replacement quickly and professionally.

Just bought my house literally a week ago and have already met 3 of your wonderful technicians (2 heating and 1 plumbing). They are polite and personable, and I feel like I can trust that they are doing what is best for my home… not just for the company’s bank account. That is difficult to find in any type of Service Company. Thank you!
Josh was wonderful. We just bought a house that needs a lot of work, and the heating systems were no exception. He looked everything over and gave me several options for the amount of work that needs to be done. I felt he was honest and sincere in his diagnosis of my many issues, and in trying to figure out the best options, while still remaining economical. He was very polite and personable as well. Thanks Josh!
