Are Electric Tankless Hot Water Heaters Efficient

Electrical units require a ton of amps to heat the water.

Are electric tankless hot water heaters efficient.

Overall tankless water heaters are more energy efficient as indicated in the chart on the previous page. Gas and electric tankless water heaters run more efficiently than the conventional water heaters of the same fuel type. In comparison gas heaters usually have between 80 and 85 percent. For homes that use 41 gallons or less of hot water daily demand water heaters can be 24 34 more energy efficient than conventional storage tank water heaters.

When you re done using hot water the appliance senses the lack of water flow and turns off the heat. If the tankless water heater is gas powered the unit may have a pilot light which can also waste energy.
