Best Tankless Water Heater Electric of 2022 – Installing an electric tankless water heater can conserve energy and minimize associated energy costs by removing the tank and just heating the quantity of water needed when it’s needed. If you’re reading this, you’ve probably already arrived at that conclusion. So, let’s have a look at some of the top electric tankless water heaters on the market to see which one is suitable for you.
Basics of Tankless Water Heater Electric
Tankless water heaters, also named demand-type or instantaneous heaters, only heat water as needed. They don’t have the identical standby energy losses as storage water heaters, which might help you save money.
How They Operate
Without the necessity of a storage tank, tankless water heaters heat water instantly. When you turn on a hot water faucet, cold water runs through a heat exchanger in the device, where it is heated by either a natural gas burner or an electric element. Tankless water heaters deliver a uniform supply of hot water as a consequence. There’s no need to wait for a hot water storage tank to fill up. The outcome of a tankless water heater, on the other hand, restricts the flow rate.
Tankless water heaters normally offer 2–5 gallons of hot water per minute. Gas-fired tankless water heaters’ flow rates are greater than those of electric tankless water heaters. However, even the biggest, gas-fired model cannot always provide enough hot water for several simultaneous usages in large houses. Running the dishwasher and taking a shower simultaneously, for example, might stress a tankless water heater. You may solve this issue by installing two or more tankless water heaters. You may also install separate tankless water heaters for equipment that utilize a lot of hot water in your house, such as a clothes washer or a dishwasher. On the other hand, additional water heaters will cost more and may not be worthwhile.
Advantages and Drawbacks
Demand water heaters are 24–34 percent more energy-efficient than conventional storage tank water heaters for homes that use 41 gallons or less of hot water each day. For households that utilize a lot of hot water — roughly 86 gallons per day — they may save 8–14 percent on electricity. In rare circumstances, installing a demand water heater at each hot water outlet may result in even higher energy savings.
A tankless water heater has a greater initial cost than a standard storage water heater; however, tankless water heaters frequently live longer and have lower operating and energy bills, which may offset the higher investment price. The majority of tankless water heaters have a lifetime of over 20 years. They also have easily replaceable components, enabling them to endure for many more years. Storage water heaters, on the other hand, survive 10–15 years.
The standby heat losses related to storage water heaters are avoided with tankless water heaters. Although gas-fired tankless water heaters have better flow rates than electric ones, if they have a pilot light, they may waste energy. When contrasted to a storage water heater, this may sometimes balance the removal of standby energy losses. The pilot light of a gas-fired storage water heater warms the water in the tank, saving electricity.
The price of running a tankless water heater’s pilot light varies depending on the type. For the model you’re considering, check the manufacturer’s documentation to see how much gas the pilot light requires. Instead of a standing pilot light, look for versions with an intermittent ignition mechanism (IID). This mechanism looks similar to the spark ignition device used on certain natural gas furnaces, as well as kitchen ranges and ovens.
Maintenance and Installation
Your demand water heater’s energy efficiency may be improved by proper installation and maintenance.
Many elements impact proper installation. These factors include climate, fuel type, local building code regulations, and safety issues, especially with relation to gas-fired water heater combustion. As a reason, it’s important to have your water heater installed by a qualified plumbing and heating specialist. When hiring a contractor, take note of the following:
- Inquire about recommendations.
- In writing, request cost estimates.
- Check to see if the firm will seek a local permit if one is required and if they are familiar with local building rules.
Start by contacting the manufacturer if you plan to install your water heater yourself. Usually, the manufacturer can provide installation and operation instructions. Also, if appropriate, check with your city or municipality for details on obtaining a permit and local water heater installation regulations.
Periodic water heater maintenance may considerably increase the life of your water heater and reduce efficiency loss. Specific maintenance advice may be found in your owner’s handbook.

Considerations When Selecting Tankless Water Heater Electric
Tankless water heaters do not all come in the same size. In truth, the size of a water heater is mostly determined by the inner circuits and systems existing within the appliance. Depending on the manufacturer, some may fit within your tight shower room, while others would require you to position them in a more open space.
Aside from the size, the form of the heater is also important to consider. For the most part, water heaters contain a rectangular design that makes them easy to place on a bathroom wall or next to a sink, which is where they’re most usually put. Due to the existence of other components, such as a small tank, some heaters are formed differently. Before you go out and purchase a heater, think about where you’ll put it.
Water heaters are designed to do one thing: heat water, but that doesn’t rule out the possibility of them doing more. Many water heaters include digital thermostats for more precise temperature readings, and some even have a self-modulating mechanism that keeps the water at the perfect temperature all of the time. These options aren’t absolutely required, but they can come in helpful in a variety of situations.
While not all water heaters are meant to be portable, some are, and you may want to be able to take one with you on vacation or if you want to use it in other locations. However, because these heaters often operate on natural gas or propane, use caution when utilizing them.
FAQs about Tankless Water Heater Electric
1. Is it true that tankless water heaters use less energy than traditional water heaters?
In general, a tankless water heater will save you more money than a tank water heater. Tankless water heaters utilize less energy to heat the water and have lower running expenses than traditional tank heaters.
2. Is it accurate that tankless water heaters are superior to traditional water heaters?
That depends on how “better” is defined. Tank water heaters provide instantaneous heating of water, but they need more energy to operate. On the other hand, tankless water heaters use less energy but take longer to heat the water since there is no tank to retain the heated water.
