Frequently Asked Questions

Answers to commonly asked questions

What is a tankless water heater?
Tankless water heaters heat water to a digitally preset temperature when your demand for hot water passes either a gas burner or electric element. Unlike conventional tank-style units which heat water 24/7, a tankless water heater only heats water on demand, making it more energy efficient.
What are the advantages of a tankless water heater?
Tankless water heaters have lower operating costs, occupy less space and can reduce energy consumption by 30-40% as compared to tank-based units. However, tankless water heater installation does require more of an upfront investment, may need venting and isn’t ideal for heavy usage.
How much does tankless water heater installation cost?
In general, purchasing and installing a tankless water heater costs about 2 to 2.5 times as much as a standard water heater because of the higher production costs of the unit, venting, and resizing the gas line and gas meter required to support the unit’s demand. However, once your tankless water heater is installed, you’ll have lower operating costs, more usable square footage, and may be eligible for federal or local tax credits and incentives.
How much can I expect to save on my monthly bill if I install a tankless water heater?
Test results have shown that a tankless gas water heater costs about 30% less to operate than an electric tank-style water heater and 20-30% less than a natural gas tank-style water heater. Keep in mind, there’s no guarantee you will achieve these exact cost savings as many factors go into the efficiency of water heaters, including your usage and behavior. Tankless water heaters do carry a much higher Energy Factor, meaning a larger percentage of the energy you use will be directly transferred to heating your water. A tankless water heater has no standing pilot light, no standby loss or burners that modulate to maintain maximum efficiency.
Can a tankless water heater be installed in the same place as my old unit?
As long as your tankless water heater has enough combustion air, it can be installed in a utility room, garage, basement, attic or placed on an outside wall. It can also be installed in a location where a tank-based water heater may not fit, such as a bedroom or bathroom. The digital temperature controller can be mounted in any room.

Tankless Water Heater Installation

Tankless water heaters (also known as on demand water heaters) heat water directly without the use of a storage tank. Upgrading your water heater system to a tankless, on demand system offers numerous advantages and benefits. Tankless units are 24 to 34 percent more energy efficient than conventional hot water heaters and they can last for 20 years or more, near twice that of water heater tanks. Tankless water heaters also feature a compact, space-saving, wall-mounted design.

Although the initial cost of a tankless water heater installation is greater than installation of a water heater tank, lower operating and energy costs are likely to offset the higher purchase price. ENERGY STAR® estimates that a typical family can save $100 or more per year with an ENERGY STAR qualified tankless water heater. You may also qualify for incentives offered by your local utility company! For additional details on the cost of having a tankless water heater installed, visit our cost guide.

Typically, tankless water heaters provide hot water at a rate of 2 to 5 gallons (7.6 to 15.2 liters) per minute. Gas tankless water heaters usually produce higher flow rates than electric models. By heating only the water you’re actually using, these units can provide energy and cost savings over time.

Advantages of a Tankless Water Heater


Proper installation and maintenance of your tankless water heater will optimize its energy efficiency over the years. Some of the other benefits to going tankless are:

- Saving water
- Lower operational costs
- Eligibility for state tax credits

Hot Water On Demand


Upgrading your water heater system to a tankless water heater is a more environmentally friendly solution as tankless systems only heat water when you need it. Also, with no water storage, there is no risk of having issues with the tank lead to leaks or flooding. Unlike traditional units, installation of a tankless water heater will enable you to have a continuous flow of hot water, but that’s not the only advantage.

Delivery, Clean Up and Haul Away


You can trust The Home Depot’s licensed and insured installers to set up your tankless system to the existing gas or electric and water lines correctly, plus clean up any debris. If you’re switching from a hot water heater with a tank, our installers will make the transition smooth by hauling away and recycling your old unit (within 30 miles of a Home Depot store location) at no additional cost. Schedule an in-home consultation today and let us show you how to save on energy costs with the installation of an on demand, tankless water heater.
