Frequently Asked Questions

Answers to common Tankless Water Heater Installation questions.

What is a tankless water heater?

Tankless water heaters raise cold water to the temperature you've digitally set when your demand for hot water passes either a gas burner or electric element. While a conventional tank-style water heater stores hot water and heats it 24/7 whether you use it or not, a tankless water heater only heats water on demand, making it more energy efficient.

What are the advantages of a tankless water heater?

A tankless water heater has lower operating costs, uses less space and can reduce energy consumption by as much as 30 to 40 percent. It also provides hot water on demand at a precise temperature for long periods of time. However, tankless water heater installation does require more of an up front investment, may need venting and is not ideal for heavy usage. On the other hand, a conventional tank constantly heats stored water, is good for high usage demands, and is economical. It can be stored in a closet, basement or garage and has a capacity ranging from 20 to 80 gallons.

How much does tankless water heater installation cost?

Generally, a tankless water heater will cost about two to two and a half times as much as a standard water heater to purchase and install. Factored into that price are the higher production cost for the unit, venting and the gas line and gas meter resizing required to support the unit's demands. However, you'll have lower operating costs, more useable square footage and you may be eligible for federal or local tax incentives and credits.

Can a tankless unit be installed in the same place as my old water heater?

As long as enough combustion air is provided, tankless water heaters can be installed in a utility room, garage, basement, attic, or placed on an outside wall. Plus, they may be installed in locations where a storage water heater may not fit, like bedrooms or bathrooms. The digital temperature controller may be mounted in any room.

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 water heater and about 20-30% less than a natural gas water heater. Note: There is no guarantee that you will achieve these exact cost savings as many factors go into the efficiency of water heaters, including your usage and behavior. Tankless units 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 and burners that modulate to maintain maximum efficiency.

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!

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 ones. By heating only the water you're actually using, these units can produce 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 large water tank there's no possibility of flooding due to a broken or damaged tank. 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 setup your tankless system to the existing gas or electric and water lines correctly, plus clean-up of 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.
