Best Electric Tankless Water Heaters FAQs
Are there any drawbacks to using an electric tankless water heater?
Like any other technology, electric tankless water heaters also have some drawbacks that you need to consider before making a purchase. The first drawback is their upfront cost, which is quite high compared to traditional storage water heaters. Additionally, you may need to upgrade your home's electrical system to handle the high power demands of an electric tankless water heater.
Another potential drawback is that electric tankless water heaters may not be able to provide enough hot water for simultaneous use in large households. For example, if someone is taking a shower while another person is running the dishwasher, the hot water supply may not be sufficient for both. This can cause inconvenience and frustration for the occupants.
Lastly, electric tankless water heaters require regular maintenance to prevent mineral buildup and prolong their lifespan. Neglecting maintenance can lead to reduced efficiency and higher energy bills.
Overall, electric tankless water heaters are a great option for those looking to save on energy costs and have an on-demand hot water supply. However, it's important to weigh the pros and cons to determine if they're the right choice for your household's needs.
Can an electric tankless water heater provide enough hot water for multiple appliances at once?
Yes, an electric tankless water heater can provide enough hot water for multiple appliances at once, but it depends on the unit's size and the flow rate of the appliances. Tankless water heaters heat water as it flows through the unit, so the amount of hot water available depends on the unit's capacity and the flow rate of the appliances using it. Generally, a larger unit with a higher flow rate will be able to supply hot water to multiple appliances simultaneously. It is important to note that electric tankless water heaters may have lower flow rates than gas-powered units, so it is important to choose a unit that is appropriately sized for the household's hot water needs. Consulting with a professional plumber or electrician can help determine the right size and type of tankless water heater for your household's needs.
How do electric tankless water heaters compare to traditional tank water heaters?
Electric tankless water heaters are a modern and energy-efficient alternative to traditional tank water heaters. Unlike traditional water heaters, tankless water heaters do not store hot water in a tank, but instead heat water on demand. This means that you only heat the water you need, which can result in significant energy savings over time.
One of the main advantages of electric tankless water heaters is their compact size, which makes them ideal for homes with limited space. They are also more durable than traditional tank heaters, with a longer lifespan and lower maintenance costs.
Another advantage is that tankless water heaters can provide a constant supply of hot water, as long as the demand does not exceed the heater's capacity. This is because the heater heats the water as it flows through the unit, and there is no need to wait for a tank to refill.
However, electric tankless water heaters can be more expensive to install than traditional water heaters, and they may not be suitable for larger households with high hot water demands. Additionally, they may require a higher upfront cost, but this can be offset by their energy savings in the long run.
Overall, electric tankless water heaters offer a more energy-efficient and space-saving solution than traditional tank water heaters, but it's important to consider your household's needs before making a decision.
How easy is it to install an electric tankless water heater?
Installing an electric tankless water heater can be relatively easy if you have some basic plumbing and electrical knowledge. The first step is to determine the location for the unit and make sure you have the necessary electrical wiring and breakers installed. It's essential to check the manufacturer's instructions for specific installation requirements and ensure that you have the right tools and equipment for the job.
Next, you'll need to shut off the water supply and drain the old tank if you're replacing an existing water heater. Once the old tank is removed, you can mount the new unit securely on the wall and connect the water supply lines. It's important to ensure that the water flow rate meets the requirements of the unit to ensure optimal performance.
Finally, you'll need to connect the electrical wiring and turn on the power to the unit. It's recommended that you have a licensed electrician perform the electrical work to ensure safety and compliance with local codes.
Overall, the installation process for an electric tankless water heater can vary depending on the specific unit and your level of experience. If you're unsure about any aspect of the installation, it's always best to consult with a professional to ensure a safe and successful installation.
How much money can I save by switching to an electric tankless water heater?
The amount of money you can save by switching to an electric tankless water heater depends on various factors such as the size of your household, your water usage, and the cost of electricity in your area. However, in general, electric tankless water heaters are more energy-efficient than traditional tank water heaters, which means you can save a significant amount on your monthly energy bills.
According to the U.S. Department of Energy, switching to an electric tankless water heater can save you up to 50% on your water heating costs.

Additionally, electric tankless water heaters have a longer lifespan than traditional tank water heaters, which means you can save money on maintenance and replacement costs in the long run.
It's important to consider the upfront cost of purchasing and installing an electric tankless water heater, as it may be higher than a traditional tank water heater.
