10 Best Electric Water Heaters 2025 in the United States

The Westinghouse 24kW tankless water heater is designed for large homes needing a steady flow of hot water without the wait typical of tank heaters. It delivers up to 5.55 gallons per minute, which can comfortably handle two showers and a sink at once, making it a strong fit for busy households. Because it's tankless, it provides endless hot water and saves floor space by mounting directly on the wall with a compact size of about 13 by 17 inches. Energy efficiency is good here, as it heats water on demand rather than keeping a tank hot all day.

The Rheem PROE50 M2 RH95 is a 50-gallon electric water heater designed primarily for households with 3 to 5 people or homes with multiple bathrooms.

With an energy efficiency rating of 0.95, it uses electricity efficiently to help lower utility bills compared to less efficient models. The unit’s dimensions (23 inches wide by 48 inches tall) make it relatively compact, which is helpful if you are replacing an older water heater and have limited installation space.
