As home appliances continue to advance in the market, the need to find a more efficient, convenient, and environmentally friendly water heater brings us to the electric tankless water heater. A research done by the U. S. Department of Energy has revealed that the market for tankless water heaters has risen by more than 200% in the last ten years. Unlike the old-fashioned and energy-wasting appliances, tankless models produce hot water as needed, thus, there is no need to store water and heat it constantly in a massive tank. This not only helps in cutting down utility bills but also in utilizing the limited space available in contemporary houses. With such a great variety of products available today, all of which claim to be energy-saving and provide hot water on demand, how does one make a decision? In this guide, we will take a look at the best electric tankless water heaters of 2024, which can provide a constant supply of hot water for your home, ensuring that you never have to endure a cold shower again.
Tankless water heaters, also referred to as instant water heaters, are modern devices that heat water without using a storage tank. When you open the hot water tap, cold water flows through a pipe into the unit and then either an electric element or a gas burner heats the water immediately. This process makes sure that you have enough hot water supply anytime you need it and do not wait for a long time.
Tankless water heaters come in two main types: gas and electric. Although both types provide the convenience of on-demand hot water and lower energy bills, electric tankless water heaters have some features that are exclusive to them and make them a great option for many homeowners.
1. Easier installation and convenience: Electric tankless water heaters are easier to install than gas types of water heaters. They do not need a gas connection or a vent, which is more advantageous than the other types, especially for homes that cannot access natural gas or propane. For instance, a survey conducted by the National Association of Home Builders revealed that more than half of newly constructed homes do not have gas lines, making electric tankless water heaters a practical choice.
2. Enhanced safety: Electric tankless water heaters are generally safer than their gas counterparts. They do not emit any greenhouse gases or carbon monoxide, thus there are no dangers of gas leakage or blast.
3. Reduced maintenance: The electric tankless water heaters are easier to maintain as compared to the gas ones. They do not have a pilot light or burners that require frequent cleaning and adjustment. There is no gas line either, so there is no chance of having a leak or corrosion of the pipe. This leads to reduced maintenance expenses and increased durability of the unit. On average, electric tankless water heaters can last up to 20 years with proper maintenance, while gas models can last up to 10-15 years. If you have hard water, it is recommended to have your electric tankless water heater serviced twice a year to prevent potential issues and ensure its longevity.
4. Environmentally friendly: The electric tankless water heaters are more eco-friendly than the gas tankless water heaters. This is because they do not emit any direct greenhouse gases into the atmosphere, which leads to a reduced carbon footprint. Furthermore, as the electricity grid evolves to incorporate more solar and wind power, the environmental footprint of electric tankless water heaters will only continue to reduce.

As technology marches forward, electric tankless water heaters are evolving into increasingly advanced appliances, boasting features that can be tailored to meet the specific demands of individual households with unparalleled precision. The market is teeming with high-performance options, each claiming to be the best, making it a daunting task for consumers to navigate through the sea of choices and determine which one truly stands out from the rest. Selecting the most suitable electric tankless water heater for your household depends on the amount of hot water you require, the size of your house, and the climate of your region. Here’s a step-by-step guide to help you select the perfect unit for your needs:
The first thing you need to do when selecting an electric tankless water heater is to determine how much hot water your household uses. Think about the number of individuals living in your home, the number of bathrooms, and the appliances that use hot water including washing machines and dishwashers. For instance, a family of four with two bathrooms will need a unit with a higher flow rate of not less than 6 gallons of hot water per minute to meet the demand during the busiest time.
Electric tankless water heaters come in two main types: whole-house units and point-of-use units. Whole-house units are meant to provide hot water to all the fixtures in the house while point-of-use heaters are smaller and meant for a certain fixture or area, for instance, a kitchen sink or a distant bathroom. A whole-house unit is ideal for most homes because it offers a central source of hot water and does not require the installation of several units in the long run.
The temperature rise is also a factor that should be taken into consideration, especially in areas where the temperature of the incoming water is low. A greater temperature increase means that a more powerful unit is needed and may demand a larger electrical supply. For instance, where the groundwater temperature is about 10°C, a temperature increase of not less than 40°C is desirable for adequate supply of hot water.
Tankless electric water heaters need an independent electrical circuit and adequate amperage to provide the necessary power. However, when selecting a unit, it is essential to consider the electrical service of your home and whether it will be capable of handling the power demand of the unit. A whole-house unit requires a 240 V, 40 A circuit while point-of-use units may require a 120 V, 20 A circuit. It is advisable to consult a licensed electrician to find out whether the electrical service in your home requires upgrading to accommodate the chosen unit.
Energy efficiency is a key consideration when choosing an electric tankless water heater, as it directly impacts your long-term operating costs and environmental footprint. Look for units with a high efficiency rating, preferably above 98%. Additionally, consider units with advanced features like self-modulating technology, which adjusts power input based on demand, further enhancing efficiency.
It is crucial to have a warranty when buying an electric tankless water heater since it guarantees the product’s quality and durability. Search for units that come with a warranty of not less than 5 years on the parts and 10 years on the heat exchanger.
The American Home Appliance Manufacturers Association (AHAM) suggests evaluating electric tankless water heaters based on their performance in maximum flow rate, output water temperature, and thermal efficiency.
