What is an electric tankless water heater?

The electric tankless water heater is an excellent alternative to a traditional water heater. It heats water as it passes through the unit and does not require any other energy source to function.

This means you won’t have to worry about paying for extra energy or adding to your home’s carbon footprint!

It can also be used in many ways. It can be used in both new and old homes, so if you want to replace a tank-style water heater with a new one, you don’t have to worry about finding a different model.

The heaters are also easy to put in, so anyone can do it without paying for the expensive labor costs that come with putting in a whole new system.

What to consider when choosing the right electric tankless water heater?

When you’re looking to buy a tankless water heater, there are a few things you’ll want to consider:

Your Budget

Electric tankless water heaters are more expensive than traditional tank-based heaters, so it’s essential to consider how much you can afford to spend upfront. If you have a small budget but large space requirements, an electric tankless water heater may not be right for you. However, if your budget is high enough to buy the best electric tankless water heater on the market today, there will be no limit on how much hot water you can get in your home or office.

Your Space

The next thing you need to consider is your space. Tankless water heaters don’t have tanks, so they don’t take up as much room as traditional models do. It would be best if you also didn’t have to worry about storing extra water in your tankless heater but keep in mind that it will require a larger-than-average electrical circuit for proper operation.

Your energy usage needs

If you’re going to be using this in a business, or if you’re looking at installing it in an apartment building or condominium, then you’ll probably want to go with a high-capacity model. These will be able to provide enough hot water for multiple people at the same time without any problems.

If you live alone or are just looking for something for your home, then a smaller model may be enough for you. However, even these can get pricey and require installation by a professional who knows what they’re doing.

Reasons to Buy an Electric Tankless Water Heater

If you’re ready to make the switch to an electric tankless water heater, you’re probably wondering what the benefits are.

Here’s why we think you should go electric:

  1. It can save you money on your energy bill
  2. It’s safer than traditional tank heaters because it doesn’t require a tank full of hot water to keep the water warm in your home—it heats the water as it goes through the system, so there’s no wait time for your shower or bath.

    This also means that if anything happens to the unit (like a power outage), there’s no risk of exploding like with traditional tank heaters!
  3. It’s more efficient than traditional tank heaters because it only uses power when heating water rather than keeping an entire tank heated at all times (which wastes energy).

FAQs

Q. What makes an electric tankless water heater different from a traditional storage-tank water heater?

The main difference between the two types of heaters is that an electric tankless unit doesn’t store hot water. Instead, it heats the cold water that flows through the unit on demand—in other words, when you turn on your sink or shower.

This means that if you have a large family or multiple people taking showers at once, there may not be enough hot water available to meet everyone’s needs at once.

However, this should decrease as more people take longer showers and use less hot water overall (something called “scheduling”).

Q. What are the pros and cons of an electric tankless water heater?

Pros:

-They are much more energy-efficient than a traditional tank-style water heater because they don’t have to store all that hot water in a tank–they just heat it when you need it.

You can save lots of money on your utility bills and reduce your carbon footprint.

-The best thing about an electric tankless water heater is that it can heat up very quickly and send hot water to multiple taps simultaneously.

This makes it perfect for busy families who need to bathe their kids before bedtime or for homes with multiple bathrooms that all need hot water at the same time.

Cons:

-The biggest con of an electric tankless water heater is that they’re pretty expensive compared with traditional gas or oil models, so they’re not right for everyone’s budget.

Q. How does an electric tankless water heater work?

Electric tankless water heaters use electricity to heat the water directly. They’re often more energy efficient than traditional tanks because they don’t need to store hot water at all times. Some models even have built-in timers so that they only heat up the amount of water you need at any given time. This can save you money and energy!

Q. What happens to the water when it’s not in use?

When you’re not using the water, it goes into a holding tank and is stored until you need it again. This helps keep your water pressure consistent so that you don’t have to worry about having a low-pressure shower or running out of hot water mid-shower.

Q. Do electric tankless heaters require any special electrical wiring?

No, electric tankless heaters do not require any special electrical wiring. You can plug them in and use them just like any other electrical appliance.

Q. Can I install an electric tankless heater myself, or do I need to hire a plumber?

You can install an electric tankless heater yourself, but it does take some know-how. You’ll want to make sure that the electrical system in your house is up to code, and that’s a job for a professional plumber.

Some electric tankless heaters are designed for do-it-yourselfers, but they’re pretty rare. If you’re not comfortable with wiring or plumbing, you should call a professional.

Q. Will I still have hot water when the power of an electric tankless heater goes out (and if so, how long)?

Yes, you will still have hot water when the power of an electric tankless heater goes out.

The length of time you will have hot water depends on how long it takes for your tankless heater to reheat. Once it has reached its normal operating temperature, you will have hot water again.

Wrap Up

Electric tankless water heaters are great because they are very safe, and they come in an array of configurations to fit almost any situation.

I hope that my list of the best electric tankless water heater can help you find a good quality product to suit your needs, no matter what those needs are.
