Average Eco-rating

Average Eco-rating: A product's balance between environmental and economic considerations. The product that has the highest Average Eco-rating is both environmentally preferred and cost-effective to purchase and own.
 72
Environmental Impact Rating: based on average annual pounds of CO2 emissions, calculated according to each technology's average annual energy consumption in kilowatt hours (kWh). The higher the rating, the less-consuming the technology is of energy and therefore the less-emitting it is of CO2.
100
Consumption Rating: based on each technology's average Energy Factor (the ratio of useful energy output from a product to the total amount of energy delivered to the product). The higher the rating, the higher the Energy Factor is of the water heating technology and the more energy-efficient it is.
60
Lifecycle Cost Rating: based on the average annual operating costs of the technology, combined with its average purchase price plus installation. The higher the rating, the more cost-effective the technology.
96
Price Rating: based on the average purchase price of the unit plus the average cost of installation for the system, including the 2009 Federal tax credit, if applicable. The higher the rating, the lower the price of the technology.
31
The higher the rating, the better.
