When it comes to heating water in your home, a tankless water heater is a cost-effective and energy-efficient option. Unlike traditional water heaters that store and continuously heat water, tankless water heaters heat water only as needed, providing a constant supply of hot water. Electric tankless water heaters are a popular choice among homeowners due to their efficiency and ease of installation. In this article, we will discuss the most efficient electric tankless water heaters on the market and provide a guide to help you choose the best option for your home.
One of the most important factors to consider when choosing an electric tankless water heater is its efficiency. Efficiency is measured by the Energy Factor (EF), which indicates how much of the energy input is converted into usable hot water. The higher the EF rating, the more efficient the water heater is. When shopping for an electric tankless water heater, look for models with a high EF rating to ensure maximum energy savings.
One of the top-rated and most efficient electric tankless water heaters on the market is the EcoSmart ECO 27. With an impressive EF rating of 0.98, the EcoSmart ECO 27 is one of the most energy-efficient models available. This unit can provide hot water for up to three showers simultaneously, making it ideal for larger households. The EcoSmart ECO 27 is also compact and space-saving, making it a great option for homes with limited space.
Another highly efficient electric tankless water heater is the Stiebel Eltron Tempra Plus. Known for its reliability and performance, the Stiebel Eltron Tempra Plus has an EF rating of 0.99, making it one of the most efficient models on the market. This unit features advanced flow control technology that ensures a constant temperature output, regardless of the water demand. The Stiebel Eltron Tempra Plus is also equipped with a self-modulating power technology that adjusts the heating element based on the water flow rate, providing energy savings and reducing electricity consumption.
If you are looking for a budget-friendly option that does not compromise on efficiency, the Rheem RTEX-13 is a great choice. With an EF rating of 0.99, the Rheem RTEX-13 is one of the most energy-efficient electric tankless water heaters in its price range.

The Rheem RTEX-13 also features a digital temperature display and adjustable settings, allowing you to customize the water temperature to your liking.
When selecting an electric tankless water heater for your home, it is essential to consider factors such as flow rate, temperature rise, and installation requirements. The flow rate of a water heater indicates how much hot water it can deliver per minute. For larger households with high hot water demand, a unit with a higher flow rate is recommended to ensure an adequate supply of hot water. The temperature rise is another crucial factor to consider, as it determines how much the water heater can increase the temperature of the incoming water. Units with a higher temperature rise are suitable for homes in colder climates where the incoming water temperature is lower.
In addition to efficiency and performance, it is essential to consider the installation requirements of the electric tankless water heater. Before purchasing a unit, make sure that your home’s electrical system can support the water heater’s power requirements. Most electric tankless water heaters require a dedicated electrical circuit with adequate amperage to operate efficiently. It is also recommended to consult with a professional plumber or electrician for proper installation and sizing recommendations.
In conclusion, choosing the most efficient electric tankless water heater is essential to ensure energy savings and consistent hot water supply in your home. Models such as the EcoSmart ECO 27, Stiebel Eltron Tempra Plus, and Rheem RTEX-13 are highly efficient options that offer reliable performance and advanced features. By considering factors such as EF rating, flow rate, temperature rise, and installation requirements, you can select the best electric tankless water heater for your home.
