What are the top features to look for in an energy efficient electric water heater?

When looking for an energy-efficient electric water heater, there are several key features you should consider to ensure maximum energy savings. Firstly, look for a water heater with a high energy factor (EF) rating. This rating indicates the efficiency of the unit and how much hot water it produces per unit of fuel consumed. The higher the EF rating, the more energy-efficient the water heater is.

Another important feature to look for is tank insulation. A well-insulated tank can help reduce standby heat loss, which occurs when hot water sits in the tank and slowly loses heat to the surrounding air. Look for a water heater with at least two inches of foam insulation.

A digital thermostat is also a useful feature to have in an energy-efficient water heater, as it allows you to set the temperature precisely and avoid overheating the water.

Finally, consider purchasing a water heater with a heat pump. Heat pump water heaters are the most energy-efficient type of electric water heater, as they use a small amount of electricity to move heat from the air or ground to heat the water.
