Water heating accounts for 20% of energy use in American homes. If we all replaced wasteful tank heaters with high-efficiency tankless hot water heaters, we could annually save hundreds of millions of dollars.

Tankless Water Cost Savings:

1. 290 million gallons of fuel oil a year
2. 164 million gallons of propane
3. 6 billion hours of kilowatt electricity

U.S. Department of Energy Efficiency and Renewable Energy estimate a household’s tankless water heater cost savings at 20% of its annual water heating cost. Since water heating is the second-largest energy expenditure in most households, this is a significant savings, and could quickly pay the cost of an energy efficient water heater.

Why heat water that is not being used?

Most energy-saving tips, such as are seen in the Consumer Reports tankless water heater review, suggest insulating storage water heaters to conserve energy-but even the best-insulated tanks will constantly reheat the same unused water. Far more cost-effective is the tankless system, which heats water only while you use it.

Everyone should, for both economic and environmental reasons, look for ways to save energy. An energy efficient water heater is one of the best ways to save energy in the home, as indicated in a Consumer Reports tankless water heater review.
