How Efficient is an Electric Tankless Water Heater? Among electric, propane and natural gas instant hot water tankless water heaters, electric models tend to be the most energy-efficient type. The energy efficiency of gas and propane reaches around 80-85%, while the electric one reaches more than 98%, which refers to the low standby loss of heat.

However, a tankless water heater's output limits the flow rate. Typically, tankless water heaters provide hot water at a rate of 2–5 gallons (7.6–15.2 liters) per minute. Gas-fired tankless water heaters produce higher flow rates than electric ones.

According to the U.S. Department of Energy, tankless water heaters can be between 8% and 50% more energy-efficient than tank-style water heaters, but the actual efficiency depends on the amount of hot water you use. If you use less than 41 gallons of hot water per day, a tankless heater is 24%-34% more efficient than a tank-style heater.

This means that not only is a tankless water heater energy-efficient, it can actually help you use less water. Size is another advantage of tankless water heaters. They are very small compared to other options.

Tankless water heaters heat water directly without the use of a storage tank. Either a gas burner or an electric element heats the water. It uses high-powered burners to rapidly heat water as it runs through a heat exchanger and deliver it directly to your faucets or shower without storing it in a tank.

A tankless water heater saves space and offers greater energy efficiency than many conventional water heaters. Best of all, this type of water heater never runs out of hot water, since there is no storage tank to deplete! Instead, you'll enjoy warm water on demand for as long as you like—as long as you're working within its limitations.
