Going Tankless: Finding the Best Electric Water Heater for Your Home at Home Depot

Evaluating the Top Brands and Models of Tankless Electric Water Heaters

As a homeowner, one of the best investments you can make is in a reliable and efficient water heating system. After over 15 years with my old traditional tank water heater, I decided it was time to upgrade to a more modern solution. After doing some research, tankless electric water heaters really caught my eye as an energy-efficient and space-saving option. The ability to heat water instantly, rather than storing it in a tank, seemed like a big advantage. And being able to mount the compact units on a wall would free up floor space in my utility closet.

I headed to my local Home Depot to compare the top brands and models first-hand. I was impressed by the wide selection of tankless electric water heaters available there, with units ranging from simple point-of-use models for just one faucet to whole-home systems capable of supplying hot water for multiple bathrooms, appliances, etc. The major brands offered at Home Depot include Rheem, EcoSmart, Bosch, Stiebel Eltron, and Eemax.

I took my time testing out display floor models and reading the detailed spec sheets. It was important for me to understand key factors like the maximum flow rate, temperature rise, and activation flow rate. I also paid close attention to the warranty terms and certifications for energy efficiency on each model. After much comparison, a few top contenders rose to the top of my list:

  • Rheem RTE 13: This efficient 13 kW model offers a solid maximum flow rate of 6.6 GPM. It can supply 1-2 bathrooms simultaneously.
  • EcoSmart ECO 27: A step up at 27 kW, this EcoSmart unit provides up to 9.5 GPM flow for larger homes. It has great reviews for consistent hot water.
  • Bosch Tronic 3000 T 2.5: For small applications, this 2.5 kW Bosch model has a compact design with advanced flow control. It’s a good choice for remote installations.
  • Stiebel Eltron Tempra 24 Plus: This whole-home 24 kW tankless water heater can supply 3-4 bathrooms at once with continuous hot water. It’s on the pricey side but promises reliability.

Taking the time to see the tankless water heaters at Home Depot in person really helped me gain a better understanding of which size and capacity would best meet my needs. The knowledgeable associates in the plumbing department were also very helpful in answering all of my questions.

Sizing Up Your Household’s Hot Water Needs

One of the biggest factors to consider when shopping for a tankless electric water heater is properly sizing the unit for your home’s requirements. Tankless heaters provide hot water on demand by actively heating it as it flows through the system, rather than keeping water stored in a tank. This allows them to heat water more efficiently, but it also means their heating capacity is limited.

Understanding the flow rate (in gallons per minute or GPM) that a unit can handle is crucial. You’ll want to select a model with a maximum GPM that aligns with your household’s peak hot water demands. For example, taking a shower might require 2-3 GPM. Running a dishwasher could use 2-4 GPM. With multiple fixtures in use at once, your peak demand can add up quickly.

Most tankless electric heater models from Home Depot provide specs on the maximum flow rate. But you’ll also want to look at the temperature rise they can achieve while maintaining those max GPM levels. The temperature rise indicates how many degrees the unit can heat incoming cold water. Many models have max flow rates of 5-6 GPM but can only sustain a 25-30 degree temperature rise at that max flow. For ideal performance with hotter output temps, look for models rated for at least a 50 degree temperature rise at their peak GPM.

Larger homes with 3 or more bathrooms, 2+ full-size showers, large jetted tubs, and other high flow fixtures will do best with a whole-home tankless model rated at 24 kW or higher. This provides enough power for sustained flow rates of 8-11 GPM or more. Smaller households or applications like a single bathroom can get by with a point-of-use tankless heater with max flow rates of 4-6 GPM.

No matter your household size, the Home Depot experts can guide you in choosing the right capacity tankless electric water heater to meet your specific needs and keep the hot water flowing.

Considering Costs: Tankless Electric Water Heater Pricing at Home Depot

In shopping for any major appliance, cost is naturally an important factor to weigh. During my research, I found the price range for tankless electric water heaters at Home Depot quite variable, largely depending on the power and capacity. Compact point-of-use models designed for one fixture start around $200-500. More powerful mid-size units adequate for 1-2 bathrooms run $500-1200. And higher capacity whole-home versions cost $1000-2000+.

With any tankless electric heater, you can expect to pay more upfront compared to a conventional tank model. But the increased energy efficiency pays off in the long run through lower monthly bills. An eco-friendly bonus is that some energy providers like PG&E offer rebates on tankless water heaters to further offset the initial price.

When comparing pricing on models at Home Depot, be sure to take note of any included warranties. Most cover parts for 5-10 years and heat exchangers for 5-12 years. Opting for an extended labor warranty for professional installation of repairs/replacement can provide added peace of mind.

While tankless electric heaters have a higher upfront cost, keep in mind you’ll save money by not needing to maintain or replace a traditional tank every 6-10 years. Plus you’ll reclaim floor space by mounting a compact unit on the wall. With potential rebates and long-term savings, a tankless water heater can be a smart investment in your home’s comfort and efficiency.

Preparing for Installation of Your New Tankless Electric Water Heater

Once I selected the right tankless electric water heater model for my needs from the wide selection at Home Depot, the next step was preparing for installation. Switching over from my outdated tank model required some electrical and plumbing considerations. The Home Depot experts were invaluable in guiding me through the process.

The first requirement was ensuring I had an adequate electrical connection for my new tankless unit. Standard models require a 220V or 240V hookup with sufficient amps to handle the heating elements. Depending on your home’s electrical panel and service, this might mean installing a new dedicated circuit and breaker. Upgrading old wiring or electrical components can add cost to the install.

Tankless heaters also introduce new venting requirements. Most venting kits include 2” PVC pipe for the intake and exhaust lines. Proper venting helps maximize efficiency and prevent moisture buildup. Make sure to position vent terminations the minimum distance from windows, doors, and other openings as specified.

You’ll also need the right plumbing connections to integrate your tankless unit with existing hot water supply and return lines. Additional accessories like isolation valves, unions, and water filters help complete the install. Don’t forget about an appropriate wall mount, bracket, or platform for supporting your new space-saving tankless heater.

To ensure optimal performance and safety, Home Depot offers professional installation services for tankless electric water heaters in most areas. Or you can hire your own licensed plumber and electrician to handle the tricky wiring and venting requirements. Just check your chosen model’s manual for all the necessary installation specs. With some planning and expert help, your tankless water heating upgrade can be up and running smoothly in no time!

Maintaining Peak Efficiency With Proper Tankless Water Heater Care

One common concern with tankless electric water heaters is their performance in areas with hard water. Hard water refers to tap water with high mineral content, usually calcium and magnesium. The minerals can build up in the internal components of tankless heaters over time, diminishing heating efficiency.

Luckily, most major tankless brands like Rheem, EcoSmart, and Stiebel Eltron have specific design features to minimize hard water issues. These include scale detection alerts, flush valves, and replaceable component filters that reduce limescale accumulation. Using a whole-house water softener system also helps reduce hard water effects.

Proper maintenance is key to maximizing the efficiency and longevity of your tankless electric water heater. Depending on your water quality, an annual descaling treatment helps remove mineral deposits from critical parts. Flushing the heat exchanger and inspecting filters should also be done yearly. Catching small buildups early prevents major performance issues down the road.

Checking the manual for your specific tankless unit provides detailed maintenance recommendations. Following the manufacturer’s directions for care, cleaning, and component replacement ensures your heater runs reliably for years to come. Don’t forget to register your product warranty and save receipts for any service parts. With a few preventative maintenance steps each year, a tankless hot water supply will keep running optimally.

Going Tankless: Making the Switch for a More Efficient Home

When my old tank water heater started showing signs of age after over a decade of use, I debated between simply replacing it with a newer tank model or finally going tankless. After much research and hands-on shopping at my local Home Depot, I decided now was the time to make the switch to tankless. And I’m happy to report after a professionally installed upgrade to a Rheem gas-powered tankless unit, I’m very glad I did!

The on demand availability of continuous hot water is incredibly convenient. I love not having to plan my showers around small tank capacities or risk running out of hot water when I need it. And the space savings from hanging the compact unit on the wall is a bonus. The sleek, modern look has also nicely updated my utility closet.

In terms of energy savings, my monthly bills show my tankless water heater is about 15-20% more efficient than my old tank model. The higher annual maintenance costs are nominal compared to the long-term savings. I’m also confident my tankless system will last significantly longer before any major repairs or replacement is needed.

If you’re considering going tankless in your own home, I highly recommend starting your research at Home Depot. The variety of trusted brands and capacity options ensures you’ll find the perfect tankless electric or gas water heater for your household’s needs. Take advantage of their expertise and professional install for optimal performance and peace of mind. I’m glad I took the tankless plunge – the unlimited hot water makes my entire home run much more efficiently. Never running out of hot water again makes it one of the best home upgrades I’ve ever made!
