Is an Electric Tankless Water Heater Worth It? Exploring the Endless Possibilities of Warm Showers and Beyond

When it comes to home appliances, few things spark as much debate as the electric tankless water heater. Is it worth the investment? Does it truly deliver on its promises of endless hot water and energy savings? Let’s dive into the swirling vortex of opinions, facts, and a few wild tangents to uncover the truth.

The Promise of Endless Hot Water

One of the most alluring promises of an electric tankless water heater is the idea of endless hot water. Imagine never having to endure a cold shower because someone else in the house used up all the hot water. This is the dream that tankless water heaters sell, and for many, it’s a dream come true. But is it really as endless as it sounds?

The reality is that while tankless water heaters can provide a continuous flow of hot water, they do have their limits. The flow rate—measured in gallons per minute (GPM)—determines how much hot water the unit can produce at any given time. If you have a high demand for hot water, such as running multiple showers simultaneously, you might still run into issues. However, for most households, an electric tankless water heater can handle the load with ease.

Energy Efficiency: Fact or Fiction?

Another major selling point of electric tankless water heaters is their energy efficiency. Traditional tank water heaters keep a large volume of water hot 24/7, which can lead to significant energy waste. In contrast, tankless heaters only heat water when you need it, potentially saving you money on your energy bills.

But here’s where things get interesting. The actual energy savings can vary depending on your usage patterns. If you’re someone who takes long, hot showers multiple times a day, the savings might not be as dramatic as you’d hope. On the other hand, if you’re more conservative with your hot water usage, the energy savings could be substantial. It’s a bit like dieting—what works for one person might not work for another.

The Environmental Angle

Let’s take a moment to consider the environmental impact. Electric tankless water heaters are often touted as a greener alternative to traditional tank heaters. Since they only heat water on demand, they reduce the amount of energy wasted in keeping a tank of water hot. This can lead to a lower carbon footprint, especially if your electricity comes from renewable sources.

But wait—there’s a twist. The production and disposal of these units also have environmental implications. The materials used in their construction, the energy required to manufacture them, and the eventual need for disposal all contribute to their overall environmental impact. So, while they might be greener in operation, the full picture is a bit more complex.

Installation and Maintenance: The Hidden Costs

Now, let’s talk about the less glamorous side of electric tankless water heaters: installation and maintenance. These units are not exactly plug-and-play. They often require significant electrical upgrades, especially if you’re switching from a gas-powered system. This can mean hiring an electrician to install new circuits or even upgrading your home’s electrical panel.

Once installed, maintenance is relatively minimal, but it’s not nonexistent. Over time, mineral buildup can affect the unit’s efficiency, so periodic descaling is recommended. This is especially important if you live in an area with hard water. While the maintenance isn’t overly burdensome, it’s something to keep in mind when considering the overall cost of ownership.

The Cost Factor: Upfront vs. Long-Term Savings

Ah, the eternal question: is it worth the upfront cost? Electric tankless water heaters are generally more expensive to purchase and install than traditional tank heaters. However, they often make up for this with lower operating costs over time. The key is to weigh the upfront investment against the potential long-term savings.

For some, the higher initial cost is a deal-breaker. For others, the promise of lower energy bills and the convenience of endless hot water make it a worthwhile investment. It’s a bit like buying a hybrid car—you pay more upfront, but the savings on gas can make it worth it in the long run.

The Aesthetic Appeal

Let’s not overlook the aesthetic aspect. Traditional tank water heaters are bulky and often take up valuable space in your home. In contrast, electric tankless water heaters are compact and can be mounted on a wall, freeing up floor space. This can be a significant advantage, especially in smaller homes or apartments where every square foot counts.

The Future of Water Heating

As technology continues to advance, the future of water heating looks promising. Smart tankless water heaters are already on the market, offering features like remote control via smartphone apps and energy usage tracking. These innovations could further enhance the appeal of electric tankless water heaters, making them an even more attractive option for homeowners.

Conclusion: Is It Worth It?

So, is an electric tankless water heater worth it? The answer, as with most things in life, is: it depends. If you value endless hot water, energy efficiency, and a smaller environmental footprint, then it might be a great investment. However, if the upfront cost and potential installation challenges give you pause, it’s worth carefully considering your options.

Ultimately, the decision comes down to your specific needs, budget, and priorities. Whether you’re looking to save money, save the planet, or simply enjoy a never-ending supply of hot water, an electric tankless water heater could be the solution you’ve been waiting for.


Q: How long do electric tankless water heaters last?

A: On average, electric tankless water heaters can last between 15 to 20 years with proper maintenance. This is significantly longer than traditional tank water heaters, which typically last around 10 to 15 years.

Q: Can an electric tankless water heater work during a power outage?

A: No, electric tankless water heaters require electricity to function. If you experience a power outage, you won’t have access to hot water until the power is restored.

Q: Are electric tankless water heaters noisy?

A: Electric tankless water heaters are generally quieter than gas-powered models. However, you may hear some noise when the unit is heating water, such as the sound of water flowing through the system.

Q: Can I install an electric tankless water heater myself?

A: While it’s possible to install an electric tankless water heater yourself, it’s not recommended unless you have experience with electrical work. Improper installation can lead to safety hazards and void the warranty. It’s best to hire a professional for installation.
