Is an Electric Tankless Water Heater Right for You? Pros, Cons, and Tips

What Is an Electric Tankless Water Heater?

An electric tankless water heater is an innovative appliance that provides on-demand hot water. Instead of storing and continuously heating a large volume of water in a tank, these units efficiently heat water only when it's required. This innovative design can reduce energy consumption and provide hot water whenever you need it.



Electric tankless water heaters are ideal for homes in regions with moderate water heating needs or for those who prioritize energy efficiency and space-saving solutions.

Pros of Electric Tankless Water Heaters

1. Energy Efficiency

Electric tankless water heaters are renowned for their exceptional energy efficiency. Traditional water heaters maintain a reservoir of hot water, which can result in standby heat loss. Unlike traditional systems that constantly expend energy to maintain a reservoir of hot water, tankless models only consume energy when hot water is actually being used, significantly reducing energy waste.

According to the U.S. Department of Energy, tankless water heaters can be up to 34% more energy-efficient for homes that use less than 41 gallons of hot water per day.

2. Endless Hot Water Supply

An electric tankless water heater ensures a consistent and uninterrupted flow of hot water, eliminating the frustration of running out during showers, baths, or while doing laundry. As long as the unit is sized correctly, it can provide a continuous supply of hot water for showers, dishwashing, and other household needs.

3. Space-Saving Design

Traditional water heaters with storage tanks can be bulky and take up valuable space in your home. Electric tankless water heaters boast a compact and space-saving design, allowing for convenient wall-mounting and making them an excellent option for homes with limited floor space or tight utility closets.

4. Lower Operating Costs

Despite a higher initial cost, electric tankless water heaters can significantly reduce energy bills over time. Their efficient operation can reduce your monthly utility costs, making them a cost-effective option over time.

1. Higher Initial Cost

Compared to traditional storage tank water heaters, electric tankless models often come with a higher initial price tag. This includes the price of the unit and potential installation expenses, especially if your home requires electrical upgrades.

2. Limited Flow Rate

The capacity of tankless water heaters to deliver an adequate supply of hot water to multiple fixtures simultaneously may be constrained. If your household frequently uses hot water in several locations at once, you may need to install multiple units or consider a higher-capacity model.

3. Electrical Requirements

Installing an electric tankless water heater might necessitate upgrading your home's electrical system to ensure it can handle the increased power demands of the unit. These units often require higher voltage and dedicated circuits to operate efficiently.

4. Maintenance Needs

To maintain optimal performance, electric tankless water heaters require regular maintenance, such as descaling to prevent mineral buildup. If maintenance is neglected, the unit's performance can decline, and its overall lifespan can be significantly reduced.

1. Assess Your Hot Water Needs

Consider your family size and daily hot water usage. A professional plumber can help you determine the appropriate unit size to meet your needs.

2. Check Electrical Requirements

Before installation, ensure your home's electrical system has the capacity to support an electric tankless water heater. If upgrades are necessary, such as upgrading your electrical panel or installing dedicated circuits, factor in the associated costs and the time required for the electrical work to be completed.

3. Look for Energy Efficiency Ratings

Choose a model with a high Energy Factor (EF) rating to maximize energy savings. Look for units that are ENERGY STAR® certified for additional peace of mind.

4. Research Brands and Models

Read customer reviews and consult with plumbing professionals to identify the best electric tankless water heaters on the market. Reliable brands are known for offering more robust warranties and providing a higher level of customer service to their clients.

5. Hire a Professional Installer

The importance of proper installation for safe and efficient operation cannot be overstated. Trust a licensed and experienced plumber to handle the installation process.

For those seeking to reduce their environmental impact and optimize their home's layout, electric tankless water heaters provide a compelling solution. However, they may not be suitable for every household, especially those with high simultaneous hot water demands or limited electrical capacity.
