Environmental Advantages of Tankless Water Heating

ENERGY SAVINGS

Like most modern conveniences, hot water comes at a cost to the environment. How great the cost depends, in large part, on the efficiency of the equipment used.

HEALTH FACTS

In addition to storing hot water, tank heaters can also harbor dangerous bacteria.

TANKLESS WATER HEATING ADVANTAGE

Water Heating accounts for 20% of energy use in American homes. If we replaced wasteful tank heaters with high-efficiency tankless models, we could annually save:

• 290 million gallons of fuel oil a year;
• 164 million gallons of propane
• 6 billion hours of kilowatt electricity

U.S. Department of Energy Efficiency and Renewable Energy Network released a brief on the benefits of demand (tankless or instantaneous) water heaters for energy efficiency. They suggest the use of tankless water heaters as a way to save up to 20% of a household's annual water heating cost.

Since water heating is the second-largest energy expenditure in most households, this is a significant savings.

Why heat water that is not being used?

Most energy-saving tips 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.

Pollution Facts

Landfills

The average storage tank hot water heater has a life span of 8-10 years, with more than 7.3 million tank water heaters discarded into landfills annually, which if laid out in a line would cover the distance from Chicago to Honolulu.

Fossil Fuels

Water heating accounts for 20% of energy use in American homes, and this energy comes from fossil fuels:

• coal
• oil
• natural gas

(electricity is typically produced by power plants that use fossil fuels).

Reducing the amount of energy used to heat water will reduce the amount of fossil fuels consumed.

Greenhouse Gases

An independent analysis has shown that replacing storage tanks with AquaStar water heaters could reduce greenhouse gas emission by 50% a year.
