How Do Electric Tankless
Water Heaters Work?

Because of potential energy savings and offering hot water on demand, electric tankless water heaters are growing in popularity. Electric tankless water heaters help reduce the energy consumption in your home by eliminating the need to maintain hot water in a large storage vessel. With high efficiency ratings and groundbreaking innovative designs, State electric tankless water heaters serve a wide range of applications, from point-of-use to whole-house. These models all deliver continuous hot water anytime it’s needed, and they can be easily installed in small spaces that could not accommodate tank water heaters, like closets, laundry rooms and bathrooms.

Instead of relying on a stored supply of hot water, electric tankless water heaters heat your home’s water when you need it. When you turn on a hot water tap, water enters the water heater and passes through the heat exchanger, where an electric resistance coil warms the water to the desired temperature. If sized correctly for your needs, hot water can always be easily delivered to your home.

While both electric tank and tankless water heaters offer unique benefits, electric tankless water heaters give you continuous hot water immediately, which can help you save on energy use in your home. However, a water heater service provider can help you determine the best choice for you as you consider usage preferences, energy supply, available space in your home, and other factors in your daily life. You may also use our water heater product selector tool to help you choose a model that fits your needs.

The main advantage of an electric tankless water heater is hot water on demand. Electric tankless water heaters can also contribute to energy savings, and they have a much smaller footprint than tank water heaters. State recommends reaching out to a licensed professional before making your water heater purchase decision. They can guide you through electrical service requirements and any additional requirements for installation.

Because they can avoid ongoing heat loss that comes with traditional tank water heaters, electric tankless water heaters offer the possibility of saving money. While there are many factors that contribute to energy costs, electric tankless water heaters will only heat the water you use instead of having a standby supply heated at all times, which means you’re only paying to heat the water you use.

State electric tankless water heaters lead the industry. With a 5-year limited warranty, State’s electric tankless water heaters can continue working properly with routine maintenance, which contributes to their lifespan and overall health. While that lifespan can vary, factors like water conditions and usage rates also encourage the health of the water heater. Routine descaling helps your unit run longer and with high efficiency.

Electric tankless water heaters do work in cold climates, but colder climates lead to colder incoming groundwater temperature. This results in the need for more energy to heat the water. Colder incoming water temperatures also limit your electric tankless water heater options to units with higher kW. These units require a larger electrical service and breaker size capacity. Once these requirements are in place, though, electric tankless is a great choice for colder climates.

What do I need to begin?
All you need is electricity and water, but we recommend consulting a licensed professional before making a final purchase decision. They will help ensure you meet electrical service requirements, have everything you need for installation, and evaluate your home’s climate.

Which size is best?
When it comes to size, consider the temperature of incoming groundwater, the required flow rate of hot water, existing electrical service, and any breaker panel restrictions that may be in place. These all impact the electric tankless water heater size that is best for you, so be sure to consider all factors before making a decision.

Where should I install it?
Because they have a small footprint, any location in your home with the appropriate hookups will work well. Offices, bathrooms, laundry rooms, closets and locations remote from the main water source are all typical installation areas.

Is venting required?
State electric tankless water heaters do not require venting.
