Excellent customer service in the store

Home Depot's Customer service in the store, was exactly what one would want under exigenct circumstances. The contractor employed by them was minimally acceptable. Their plumbing of black gas pipe, however, leads a lot to be desired. My gas line leans so far from plumb it rubs against the water heater. Moreover it was necessary to oversee every twist and turn of the pipe wrenches.

Install went smooth.

Had to tighten a connection between the water main & water meter due to a slight drip but otherwise the install was done smoothly and only took a little over an hour to get it completed.

Frequently Asked Questions

What is a tankless water heater?

On a tankless water heater, you can set the temperature digitally. Once you set the temperature, the water passes through the heat exchanger and rises to the temperature you set. While a conventional tank-style water heater stores hot water and heats it 24/7, a compact tankless water heater only heats water on demand making it more energy efficient.

What are the benefits of a tankless water heater and how does it differ from a traditional unit?

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 can provide continuous hot water at a precise temperature. However, it does require more of an up front investment, may need venting and is not ideal for heavy usage. 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 more do tankless water heaters cost to purchase?

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/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.

Advantages of a Tankless Water Heater

Tankless water heaters (also known as on-demand water heaters) heat water directly without the use of a storage tank. Typically, tankless water heaters provide hot water at a rate of 2 to 5 gallons (7.6 to 15.2 liters) per minute, and gas-fired tankless water heaters 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.

Upgrading your water heater system to a tankless, on-demand system can offer numerous advantages and benefits. They are 24 to 34 percent more energy efficient than conventional water heaters, they can last for 20 years or more, near twice that of standard water heaters, and they feature a compact, space-saving, wall-mounted design

Although the initial cost of a tankless water heater with installation is greater than that of a conventional hot water heater, lower operating and energy costs could 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 or benefit from state tax credits.

Proper installation and maintenance of your tankless water heater will optimize its energy efficiency, and you can trust The Home Depot’s professional, licensed and insured service providers to do the job right.
