The right one for your home depends on how big your family is and, therefore, how much hot water you’ll need. Gas water heaters are more efficient than electric water heaters in the long term, but electric heaters are generally less expensive to install. They also don’t require a ventilation system, which means you don’t necessarily need to put them in an area with existing pipes. Electric water heaters can be installed almost anywhere, even in small spaces. Tankless water heaters are relatively new home appliances that ensure you have piping hot water at the ready while taking up as little space as possible and using energy efficiently. Tankless water heaters can be up to 34% more efficient than a conventional storage tank-type water heater, which can save the average family $100 per year.

Best Whole House Electric Tankless Water Heaters Review
Compared to regular water heaters with tanks, the flow rate of tankless water heaters is lower. Flow rates range from around 2.5 GPM for smaller units, with much larger units reaching up to 11 GPM. The water can reach 140°F, however, this will be lower in much colder climates. The temperature can be changed, if need be, in one-degree increments by simply turning the controller.

Temperature is adjustable in one-degree increments and it’s able to provide up to 3.17 gallons of hot water per minute. Condensing units tend to cost more than non-condensing units but also run more efficiently than non-condensing units. The additional heat exchanger adds to the cost of a condensing tankless water heater. Non-condensing units need proper venting to handle higher temperatures. Gas-powered tankless water heaters can vary in cost based on the amount of British Thermal Units (BTU) they can put out.

If upfront prices are a concern, considering a point-of-use heater as an alternative to a whole house heater, may be a viable solution. By far the most popular benefit to having a tankless water heater is its energy efficiency. In fact, despite its high upfront cost, a tankless water heater will pay for itself in a couple of years thanks to lower energy bills and a long lifespan. The first natural gas fueled water heater on our list is the Rinnai RU160iN Model Series, tanking our sixth place spot.
Rinnai V65iN V Model Series
Despite its power, this Takagi is tied with the Rinnai 160iN for energy efficiency with a 0.93 UEF and also has an ENERGY STAR® certification. Of course, with great power comes great cost—the Takagi is the priciest water heater we reviewed. The specification covers high-efficiency gas storage, whole-home gas tankless, solar, and high efficiency electric storage water heaters. Products must meet minimum requirements for energy efficiency, hot water delivery, warranty period, and safety. The product information page or spec sheet (downloadable on product information pages under Documents) for each of our tankless water heaters lists the gallons per minute at certain degree rises. The smart modulating technology adjusts power-input based on the temp setting and flow rate in real-time.

In addition, Jones points out that most people should set the temperature between 110 and 120 degrees F for the sake of safety. This model retails for under $650, which is a good value when you consider its performance and long-term savings from its energy efficiency. Gas-powered tankless water heaters need to be properly ventilated to work effectively. Tankless water heaters generate exhaust gases, so it’s important to vent them to the outside of your home to prevent the buildup of harmful gases like carbon monoxide. The first thing to decide when choosing your electric tankless water heater is whether you desire a whole house or a point-of-use heater.

Because a Tempra® is a tankless water heating system, it is not subject to seismic building code. There is no need for the preventative construction required with a tank water heater. A Stiebel Eltron Tempra® doesn't cost any more to purchase than a conventional tank water heater. If there are high flow showers, or another out-of-the-ordinary situation, please call or email for advice. Stiebel Eltron service representatives provide assistance and make recommendations on sizing, or any other matter concerning our water heaters, to both homeowners and professional installers.

If you don’t want inconsistently delivered hot water, your new tankless water heater will have to be able to meet or exceed this demand. You can typically find the flow rate of an appliance or fixture in the product’s specifications or on the manufacturer’s website. Do you plan on a whole-house heater, where the hot water supply will be accessible from any location in your home?

Water pipes and electrical conduits are small in diameter, so units are generally very compact and surprisingly slender. That said, dimensions might be important when installing point-of-use models. Those who live in compact modern homes will want to take a close look at the EcoSmart ECO 11. Rated for a maximum of 3.1 GPM, this affordable unit can provide constant hot water for a shower and low-flow faucet simultaneously. It is one of few electric tankless water heaters that uses the accurate Uniform Energy Factor (UEF) standard, with outstanding efficiency of 99.8 percent. Point of use tankless water heaters provide an alternative or supplement to models designed to supply a whole house.
Increase that to twice a year if you live in a very cold area or if you consistently have hard water. Temperature rise refers to the difference between local groundwater temperatures and your desired hot water temperature. This then informs how much energy must be used in order to heat your water.
The temperature is also clearly visible on the easy-to-read LED display. Use The Home Depot Mobile App to see our selection of tankless water heaters and have it delivered to your doorstep. Yes, over time you can save money with a tankless water heater due to its increased energy efficiency.
Manual controls allow temperature adjustments from 80 to 140 degrees Fahrenheit. Its 44,358 BTUs provide 3.17 gallons of hot water per minute using just one 60 amp breaker and 240 volts. Versatility is why we chose the Rheem 18kW Tankless Electric Water Heater for our second spot. At 18 watts, it produces 61,419 BTUs which makes it useful as a point-of-use heater or as a whole house heater for a family of two. Up to 4.4 gallons per minute of hot water can be ready at a moment’s notice. As an industry leader for almost 100 years, Rheem backs it all up with a five year warranty on heating components and a year on other parts.
Units with 199,000 BTU capability will cost more than those with lower numbers. Units with higher BTUs can heat water quicker than those with fewer BTUs. Labor costs will vary based on the amount of time it takes to complete the job and the amount of work needed. Tank-style water heaters often need to be fully replaced for minor issues.
EcoSmart is a trusted name for pool heaters, so they know how to heat water. This heater supplies up to 6.5 gallons of hot water per minute using 27kW of electricity. Although, if the inlet water is very cool, the hot water output can go down to about 2.7 gallons.
Point-of-use heaters are great for large houses with long plumbing lines, remodels or additions, appliance applications or remote sink locations. Whole house heaters provide all of your hot water needs from a central location. This water heater offers precise temperature settings from 80 to 140 degrees Fahrenheit in one- degree increments. Eemax offers its warranty of five years against leaking and one year for parts. Water flow rate is constantly monitored and power needs are automatically adjusted accordingly.
The unit's maximum flow rate is 5.3 GPM, and it can support two showers simultaneously in most conditions. Temperature settings for this model range from 80 to 140 degrees F, which is plenty of heating power for most applications. But that falls short of the maximum 160 degrees F some tankless water heaters are capable of.
